Star Trek: The Next Generation

The top prize is capped at 10,000x your stake. On a $1 spin that is $10,000; on $0.20 it is $2,000. 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.

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 medium–high volatility game.

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.

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.

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).

Mystery symbols

Special symbols that all reveal the same randomly chosen regular symbol, which can complete several wins at once.

• 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 96.46% RTP, clearing $1,000 of wagering costs about $35.40 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 medium–high volatility we suggest a budget of at least 250 spins. This is what that means for Star Trek: The Next Generation.

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