Giga Zombies GigaBlox is played on a 6×5 grid with scatter pays.

How winnings work (members only)
What 96% 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.
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.
What 96% RTP means
Expected return = stake × 96%
Over $100 of total bets, the long-run average loss is $4.00
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.
The published hit frequency is 35.08%, meaning roughly one spin in 2.9 returns something — though many of those wins are smaller than the stake.
Features explained (members only)
4 features explained: free spins, multipliers, wild symbols, tumbling reels
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.
Wild symbols
Wilds substitute for regular paying symbols to help complete winning combinations. They do not normally replace scatter or bonus symbols.
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.
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 which RTP version you're playing. Yggdrasil offers this game at 96%, 94%, 90.5%. Open the game rules at your casino and prefer sites running the 96% version.
- Bonus wagering: at 96% RTP, clearing $1,000 of wagering costs about $40.00 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.
