How to play Siberian Storm Megajackpots (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.

Siberian Storm Megajackpots is played on a 5×5 grid with 720 ways.

Set your stake. Choose your total bet per spin between $0.50 and $250. Wins are paid as multiples of this stake.
Check the paytable. Open the game's info screen to see what each symbol pays and the exact rules for this version.
Spin. Each spin's result is decided by a certified random number generator, independent of previous spins.
Trigger the bonus. Land the required scatter symbols to start the free spins feature.

How winnings work (members only)

What 93% RTP costs per $100 wagered, the 600,000x max win at a $1 stake

The top prize is capped at 600,000x your stake (including the jackpot). On a $1 spin that is $600,000; on $0.20 it is $120,000. When the cap is reached the round usually ends immediately.

What 93% RTP means

Expected return = stake × 93%
Over $100 of total bets, the long-run average loss is $7.00

RTP is a long-run average across millions of spins. Any single session can finish far above or below it, especially on a high volatility game.

Features explained (members only)

4 features explained: expanding wilds, free spins, wild symbols, progressive jackpot

Expanding wilds

When an expanding wild lands, it grows to cover its whole reel, turning one symbol into a full column of wilds.

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.

Wild symbols

Wilds substitute for regular paying symbols to help complete winning combinations. They do not normally replace scatter or bonus symbols.

Progressive jackpot

A jackpot that grows with a share of every qualifying bet until someone wins it. Contributions are funded from the game's RTP.

Strategy tips (members only)

Size your stake to the volatility. High volatility concentrates the return in rare, large wins. Long losing runs are normal. Keep stakes small (around 1% of your session budget or less) so you can ride out the swings. A simple rule: bring at least 300 spins' worth of budget, so a $50 budget suggests a stake of about $0.17.

3 more tips and a session planner

Check jackpot eligibility. Some progressive jackpots require a minimum or maximum stake to win the top prize. Part of every bet funds the jackpot, so base-game RTP is lower.
Bonus wagering: at 93% RTP, clearing $1,000 of wagering costs about $70.00 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.
