How to play Crystal Towers (members only)
Wins pay for groups of matching symbols that touch horizontally or vertically. Larger clusters pay more, and winning clusters usually disappear to make room for new symbols.
Crystal Towers pays with cluster pays.
- Set your stake. Choose your total bet per spin between $0.10 and $20. 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.
- Optional bonus buy. Where permitted, pay a fixed price to start the bonus directly.

How winnings work (members only)
What 96.37% RTP costs per $100 wagered
Because wins don't depend on lines, every symbol in view can count towards a pay. The paytable lists how many matching symbols each tier needs.
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.
What 96.37% RTP means
Expected return = stake × 96.37%
Over $100 of total bets, the long-run average loss is $3.63
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: tumbling reels, free spins, bonus buy, cluster pays
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.
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.
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).
Cluster pays
Wins are formed by groups of matching symbols touching horizontally or vertically, rather than along lines.
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.
4 more tips and a session planner
- Check which RTP version you're playing. Big Time Gaming offers this game at 96.37%, 96.36%. Open the game rules at your casino and prefer sites running the 96.37% version.
- 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 96.37% RTP, clearing $1,000 of wagering costs about $36.30 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.
