Vault Cracker Megaways

The top prize is capped at 2,484x your stake. On a $1 spin that is $2,484; on $0.20 it is $496.80. When the cap is reached the round usually ends immediately.

Because winning symbols tumble away and are replaced, one paid spin can produce a chain of wins. All of them count towards that spin's total.

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.

The published hit frequency is 31.15%, meaning roughly one spin in 3.2 returns something — though many of those wins are smaller than the stake.

Tumbling reels

After a win, the winning symbols are removed and new ones fall into their place. This can create several consecutive wins from a single paid spin. Also called cascades or avalanches.

Respins

Selected reels or the whole grid spin again without a new stake, usually triggered by a specific symbol combination or near-miss feature.

Hold and win

Landing enough special cash or coin symbols starts a respin feature: those symbols lock in place, the respin counter resets each time a new one lands, and their values are collected when the feature ends.

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).

Bonus wheel

A wheel feature that awards a prize, multiplier, jackpot or entry into another bonus round.

Megaways

A licensed mechanic where the number of symbols on each reel changes every spin, so the number of ways to win can run into the hundreds of thousands.

• 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 95.68% RTP, clearing $1,000 of wagering costs about $43.20 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.

For high volatility we suggest a budget of at least 300 spins. This is what that means for Vault Cracker Megaways (bets from $0.10 up to a maximum bet of $50).

Averages only: a short session can end far above or below them. Set a loss limit before you play.
