How we stay alive

Ioannis Kavouras created Roulette 30 in 2010 first and foremost as a project of love and passion. Monetary gains were never a concern. This is still our philosophy: “for the love of the game”. However, although we would prefer from an aesthetics point not to, we do run casino ads on our site. We do this for two reasons.

  1. They provide us with some income to compensate the ever increasing time, effort and resources we invest on this project.
  2. They promote really good online casino venues. Honest companies with a great selection of fair live and 3d roulette games and fast withdrawal times. We constantly review and evaluate our advertisers so we can offer you the best choices if you want to play roulette online.

How we are different

Most roulette sites out there are in essence casino portal sites that provide some basic info about roulette as an afterthought and as an excuse to appear in search results. They were created with the sole purpose of making money with affiliate casino links. Their owners have no idea about roulette and their contents are copied and paraphrased from somewhere else. And there are also those “roulette expert sites” in which all the content serves only one purpose: to convince you to buy their “winning system”.

There’s nothing wrong trying to make a buck from your site. Everyone would like that, me included. But when your driving force is making money from roulette players and you have no real knowledge or love for the game, then naturally your site will be either a casino promotion prospect with thin real content or even worse a sales pitch about your method of winning full of misinformation and false promises.

Roulette 30 is different. Thanks for reading.

I am a roulette player. Neither an “editor” nor a “mathematician”. The difference is that I put my money where my mouth is. Most roulette sites are written by editors who have never placed a bet. They recycle knowledge and recite Wikipedia. And they are paid to write. I have paid dearly for every single word I write. I have invested money, time, aspirations and grey matter in roulette.

In my 20 years as a roulette player, I have played everywhere, I have tried innumerable of roulette strategies, studied, created or dismissed countless ideas and done all the mistakes you could possibly do. I learned and I’m here to tell you about it. I can’t fight luck and i can’t control randomness. But I do know what works and what doesn’t, what mistakes you should avoid and what you need to win.

How Online Slots Work: Reels, Paylines, RTP and Volatility Explained

Slots are casino games where you choose a stake, spin the reels, and win when matching symbols land on a payline.

If you're new to slots, the two things worth understanding before you play are RTP, which reflects the long-term return a game is designed around, and volatility, which tells you how often wins tend to land and how large they may be.

The Anatomy Of A Slot

A slot is built from a few simple components. Reels are the vertical columns that spin. Rows are the horizontal positions where symbols can land. Paylines are the fixed patterns across the reels that the game pays on – a symbol combination has to land on an active payline to count as a win.

Some slots use a different system called ways to win, where matching symbols can land in multiple positions across the reels rather than on a fixed line. The two systems work differently, and the paytable will always tell you which one applies.

How to Play Online Slots Step By Step

The process is straightforward once you know the parts. Here's how a typical session works.

  • Create an account and log in to access the game lobby and deposit funds before you play.
  • Choose a slot and check its information panel before committing. Minimum and maximum bet, paylines or ways to win, volatility, and available features are all worth a look.
  • Set a budget before your first spin. Decide how much you're comfortable spending and treat that figure as your limit for the session.
  • Read the paytable. It tells you what symbols pay, how winning combinations work, and how any bonus features are triggered.
  • Place your stake and spin. If matching symbols land on an active payline or in a winning combination, the game pays according to its rules.

How a Spin Works: The RNG Explained

Every spin is decided by a random number generator, or RNG, a software that produces a random outcome each time you play. Because each spin is independent, the result of one has no effect on the next.

That means you can't predict or influence what a spin will produce. A run of losses doesn't make a win more likely, and a near-miss doesn't change the next result. Each spin starts from zero.

How to Read a Slots Paytable

The paytable is the game's rulebook. It shows which symbols pay the most, which combinations trigger wins, and how bonus features work. It also covers the betting structure – paylines, stake range, and any conditions attached to jackpots or bonus rounds.

Paytables matter because no two slot games work exactly the same way. One game may pay from left to right only, another may pay in multiple directions, and others use a ways-to-win system instead of fixed lines. Reading the paytable before you spin removes the guesswork.

RTP and Volatility Explained

RTP stands for Return to Player. It's the percentage a slot is designed to return to players over a very large number of spins. A game with 96% RTP is built around a higher long-term return than one with 92% RTP, but RTP reflects averages across millions of spins, not what you'll see in a single session.

Volatility describes how wins are distributed across those spins.

  • High volatility: wins land less often but tend to be larger when they do. Suited to players comfortable with longer gaps between wins.
  • Low volatility: wins land more frequently but are usually smaller. Suited to players who prefer a steadier rhythm.

Neither is better. The right choice depends on how you want to play.

Bonus Features Explained

Free spins

Free spins let you spin without paying for each turn. They're usually triggered by landing a specific symbol or combination shown in the paytable.

Wilds

Wild symbols substitute for other symbols to help complete a winning combination. The exact rules – which symbols a wild can replace and whether it carries a multiplier – vary by game, so check the paytable.

Scatters

Scatter symbols usually trigger a bonus feature rather than paying only on a payline. In most games, landing a set number of scatters is what unlocks free spins or a bonus round.

Multipliers

Multipliers increase a win by a fixed amount: 2x, 5x, 10x, and so on. They can apply to a single win during base play or to wins inside a bonus feature, depending on the game.

Megaways

Megaways is a slot format where the number of ways to win changes with every spin. Instead of fixed paylines, the game produces a different number of winning combinations each time, which can run into the hundreds of thousands.

How to Choose a Slot

Start with the fundamentals rather than the visual theme. Check RTP, volatility, and the minimum stake before committing to a game. Those three figures tell you more about how a session is likely to feel than the theme or the number of features.

Match the game to how you want to play. A lower-volatility slot suits a player who wants more frequent, smaller wins and a longer session on a modest budget. A higher-volatility slot suits someone who's comfortable with variance and is playing for larger potential returns. If you're drawn to larger potential prizes, jackpot slots are worth exploring. Fixed and progressive jackpots work differently, so check the rules before you play.

The games themselves are built by a range of slot providers, each with their own style and specialisms, so it's worth finding out which ones make the games you enjoy most.

The clearest rule: if the paytable doesn't make sense, find a different game. A slot you understand is always a better choice than one you're guessing at.

Setting a Budget and Playing Responsibly

A budget is the simplest way to keep your session in control. Slots move quickly, and it's easy to spend more than you intended if you haven't set a clear limit before you start.

Play only with money you can afford to lose. Don't treat gambling as a way to generate income or cover financial shortfalls. If you want support, resources are available at begambleaware.org.

Key takeaways

  • A slot is a game where you stake, spin, and win when matching symbols land on an active payline or winning combination.
  • Reels, rows, paylines, and ways to win are the core building blocks of slot structure.
  • Every spin is controlled by an RNG – outcomes are random, independent, and can't be predicted or influenced.
  • The paytable tells you everything you need to know about how a specific game pays and what its features do.
  • RTP reflects the long-term return a game is designed around; volatility tells you how wins are distributed.
  • Set a budget before you play and stick to it. Slots move fast and limits matter.

FAQs

Are online slots rigged?

No. Licensed online slots use RNG software to produce random outcomes on every spin. Operators regulated by the UK Gambling Commission are required to use certified RNG systems and undergo independent testing. The result of each spin is random; it isn't fixed or manipulated.

What is RTP?

RTP stands for Return to Player. It's the percentage a slot is designed to return to players over a very large number of spins. A game with 96% RTP will, in theory, return £96 for every £100 wagered over millions of spins, though individual sessions will vary widely.

What does volatility mean?

Volatility describes how a slot distributes its wins. High volatility means wins are less frequent but can be larger; low volatility means wins land more often but tend to be smaller.

What is a payline?

A payline is the pattern that symbols must land on for a win to be paid. Some slots use a fixed number of paylines; others let you choose how many to activate. Games using a ways-to-win system don't use paylines at all.

Can you predict or influence slot outcomes?

No. Each spin is independent and determined by an RNG. Previous results have no effect on the next spin.

How do bonus features work?

Bonus features are triggered by landing specific symbols or combinations listed in the paytable. The most common are free spins, wilds, scatters, multipliers, and Megaways-style variable win systems. Each game defines its own rules, so the paytable is always the place to check.

Blackjack Surrender: The Hands Where Folding Half Your Bet Is the Right Call

Surrender is a blackjack playing option that lets you forfeit your hand and recover half your wager.

After seeing your two-card hand and the dealer's upcard, if you judge your chances of winning to be poor, you can surrender instead of playing the hand out. The dealer removes half your bet, takes your cards, and moves on.

Not every casino offers surrender, and most players instinctively avoid it, but used correctly, it's the mathematically correct play in a handful of specific situations.

When Does Surrender Make Sense?

Surrender makes sense when your expected loss on the hand exceeds 50%. Since surrendering always costs you exactly half your bet, the rule is straightforward: surrender only when your chances of winning are below 25% (i.e. you'll lose more than 75% of the time).

Take a hard 16 against a dealer 10, one of the worst situations in blackjack. In a six-deck game, your options break down like this:

  • Hit: win 23.4%, lose 76.6% – expected loss of $53.20 per $100 bet
  • Stand: win 22.8%, lose 77.2% – expected loss of $54.40 per $100 bet
  • Surrender: guaranteed loss of $50.00 per $100 bet

Surrendering saves you $3.20 to $4.40 per $100 compared to playing the hand. Over time, that difference adds up.

Making Surrender Worthwhile

Surrender strategy depends on three variables: the number of decks in play, whether the dealer hits or stands on soft 17, and the composition of your hand. The sections below cover the most common scenarios.

In the strategies below, "Rh" means surrender if available, hit if not. "Rs" means surrender if available, stand if not. "Rp" means surrender if available, split if not.

Basic Strategy for Late Surrender: Six Decks, Dealer Hits Soft 17

This is the most common rule set you'll encounter in online and land-based casinos.

  • Hard 15 vs. dealer 10: Rh
  • Hard 15 vs. dealer Ace: Rh
  • Hard 16 vs. dealer 9: Rh
  • Hard 16 vs. dealer 10: Rh
  • Hard 16 vs. dealer Ace: Rh
  • Hard 17 vs. dealer Ace: Rs
  • Pair of 8s vs. dealer Ace: Rp

Here's the reasoning behind each hand:

Hard 15: Hitting hard 15 against a dealer 10 averages 50.4-50.5 cents with 10-5 or 9-6, and 50.01 cents with 8-7 – all above the surrender threshold, though the 8-7 is a negligible difference. Against a dealer Ace, hitting costs 59.5-59.9 cents depending on composition, making surrender clearly correct. Against a dealer 9, average losses when hitting fall to 46.8-47.2 cents, so you hit instead.

Hard 16: With one more bust card than hard 15 (any 6 through 10 busts you), surrender is correct against a dealer 9, 10, or Ace. Hitting average losses: 50.6 cents vs 9, 53.6-53.7 cents vs 10, 54.0-54.1 cents vs Ace – all above the 50-cent surrender cost.

Hard 17 vs Ace: Normally, you stand on hard 17, but when the dealer hits soft 17, their average final hand improves enough that standing on 17 becomes costly. Surrender if the option is available; stand if it isn't.

Pair of 8s vs. Ace: Splitting 8s is almost always correct, but against a dealer Ace in a hit-soft-17 game, splitting produces an average loss of 51.7 cents per dollar of your original wager – above the 50-cent surrender threshold. Surrender the pair; split only if surrender isn't offered.

Basic Strategy for Late Surrender: Six Decks, Dealer Stands on Soft 17

When the dealer stands on soft 17, you surrender less often. A dealer who stands on soft 17 ends up with a weaker average final hand than one who hits it, which shifts more situations in the player's favour.

  • Hard 15 vs. dealer 10: Rh
  • Hard 16 vs. dealer 9: Rh
  • Hard 16 vs. dealer 10: Rh
  • Hard 16 vs. dealer Ace: Rh

Note: hard 15 vs. Ace drops off the surrender list entirely. When the dealer stands on soft 17, hitting hard 15 against an Ace averages only 47.6-48.3 cents in losses, below the 50-cent surrender threshold. You hit instead.

Hard 16 still warrants surrender against 9, 10, and Ace. Average losses when hitting: 50.5 cents vs 9, 53.5 cents vs 10, 51.4-51.6 cents vs Ace.

Basic Strategy for Late Surrender: One Deck, Dealer Hits Soft 17

Single-deck blackjack with surrender is rare. If you find it, check the other rules carefully. Single-deck games often offset player-friendly rules elsewhere.

  • Hard 15 vs. dealer Ace: Rh (but hit if your 15 is 8-7 – average loss drops to 48.3 cents)
  • Hard 16 vs. dealer 10: Rh
  • Hard 16 vs. dealer Ace: Rh
  • Hard 17 vs. dealer Ace: Rs (10-7 only; hit with 9-8, where losses fall to 49.1 cents)
  • Pair of 7s vs. dealer 10: Rs
  • Pair of 7s vs. dealer Ace: Rh

The pair of 7s is the hand to watch in single-deck H17 games. Against a dealer 10, the next best play is to stand, with an average loss of 51 cents. Against a dealer Ace, the next best play is to hit, with a 52.3-cent average loss.

Basic Strategy for Late Surrender: One Deck, Dealer Stands on Soft 17

The surrender list shrinks further. Only two hands qualify:

  • Hard 16 vs. dealer 10: Rh (average losses when hitting: 50.7 cents with 10-6, 51.2 cents with 9-7)
  • Pair of 7s vs. dealer 10: Rs (average loss when standing: 51 cents; hitting is worse at 51.5 cents)

Don't surrender 7-7 against a dealer Ace in this game. Hitting averages only 49.4 cents in losses, below the surrender threshold.

A Word About Early Surrender

Early surrender lets you forfeit your hand before the dealer checks for blackjack. It's a significantly more favourable rule for players than late surrender, and it's extraordinarily rare. You're unlikely to encounter it outside of certain European and Asian casinos or speciality blackjack variants with offsetting rules elsewhere.

Basic strategy for early surrender:

  • Against a dealer Ace: surrender with hard 5-7, hard 12-17, and pairs of 3s, 6s, 7s, or 8s
  • Against a dealer 10: surrender with hard 14-16, or pairs of 7s or 8s

For most players, late surrender is the relevant strategy. Focus there, especially in online blackjack, where surrender is more commonly available than at land-based tables.

More Tips for Blackjack Surrender

  • To check if a casino offers surrender, look at the rules placard on the table, or ask the dealer. Online, check the game's rules summary before playing.
  • In US casinos, surrender is only available after the dealer peeks for blackjack when showing an Ace or 10. If the dealer has blackjack, surrender is off the table, and you lose your full bet (unless you also have blackjack). This is late surrender, the strategy covered in this article.
  • To signal surrender at a live table, either announce it verbally ("surrender") or draw an imaginary line from left to right across the felt with your index finger. Casinos vary in which they accept.
  • Using a correct late surrender strategy reduces the house edge by approximately 0.07% in multiple-deck games. It also stabilises your bankroll by eliminating the worst expected-value hands.
  • For card counters, surrender is especially valuable. Knowing when to surrender based on the count significantly moderates bankroll swings. See Chapter 10.7 in the Ultimate Blackjack Strategy Guide for the surrender "Fab Four" indices.
  • Not all online blackjack games offer surrender. Check the game's rules before playing.

Key Takeaways

The following rules apply to the most common casino scenario: six decks; dealer hits on a soft 17.

  • Surrender hard 16 against a dealer 9, 10, or Ace
  • Surrender hard 15 against a dealer 10 or Ace
  • Surrender hard 17 against a dealer Ace
  • Surrender a pair of 8s against a dealer Ace (split if surrender isn't available)
  • Never surrender 8-8 against a dealer 9 or 10 – split instead
  • If the dealer stands on soft 17, drop hard 15 vs. Ace and hard 17 vs. Ace from the surrender list
  • Surrender only applies before you draw additional cards – you can't surrender after hitting
  • The mathematical threshold: surrender when your expected loss from playing exceeds 50% of your bet
