How to play Big Brown (members only)
Instead of fixed lines, matching symbols on adjacent reels pay in any position, starting from the leftmost reel. The more matching symbols there are on each reel, the more ways the combination pays.
Big Brown is played on a 6×4 grid with 4,096 ways.
- Set your stake. Choose your total bet per spin between $0.05 and $12.50. Wins are paid as multiples of this stake.

How winnings work (members only)
What 96.08% RTP costs per $100 wagered, the 9,000x max win at a $1 stake
The top prize is capped at 9,000x your stake. On a $1 spin that is $9,000; on $0.20 it is $1,800. When the cap is reached the round usually ends immediately.
Multipliers are applied to wins as they land; in many games several multipliers add together or multiply each other, which is where the largest wins come from.
What 96.08% RTP means
Expected return = stake × 96.08%
Over $100 of total bets, the long-run average loss is $3.92
RTP is a long-run average across millions of spins. Any single session can finish far above or below it, especially on a medium volatility game.
Features explained (members only)
5 features explained: wild symbols, gamble feature, bonus buy, free spins and more
Wild symbols
Wilds substitute for regular paying symbols to help complete winning combinations. They do not normally replace scatter or bonus symbols.
Gamble feature
After a win you can risk it on a double-or-nothing guess, such as the colour of a card. It does not improve the game's long-term return.
Bonus buy
Lets you pay a fixed multiple of your stake to enter the bonus feature straight away instead of waiting for it to trigger. It raises variance considerably and is not available in every country (it is banned in the UK).
Free spins
A bonus round of spins played at no cost to your balance, usually triggered by landing three or more scatter symbols. Wins during the round are added to your balance, and many games let you retrigger extra spins.
Multipliers
Multipliers increase a win by a set factor, such as 2x or 10x. They can be attached to symbols, applied to a whole spin, or grow during a feature, and are a main driver of the biggest wins.
Strategy tips (members only)
- Size your stake to the volatility. Medium volatility balances hit rate and win size. Expect dry spells between features, but not extreme swings. A simple rule: bring at least 200 spins' worth of budget, so a $50 budget suggests a stake of about $0.25.
3 more tips and a session planner
- Treat bonus buys as high-risk. Buying the feature concentrates your budget into a few large-variance rounds. Many results return less than the price paid. Read our bonus buy guide first.
- Bonus wagering: at 96.08% RTP, clearing $1,000 of wagering costs about $39.20 on average. Check the bonus terms, as some casinos exclude specific games. Run your numbers in the wagering calculator.
- Set limits before you spin. Decide your loss limit and session time in advance and stop when you reach either. No pattern or betting system changes the outcome of a spin.
