Frequently Asked Questions
What does the Fat Symbol mechanic do during free spins?
During free spins, you select one symbol that starts as 1x1 and grows larger each time you land a matching symbol, expanding up to 7x7. The larger the Fat Symbol becomes, the more winning clusters it can form on the 7x7 grid.
How many free spins do I get, and what triggers them?
Landing 4 to 7 scatters triggers 5 to 8 free spins respectively. The more scatters you land, the more spins you receive.
What is the Pre-Bonus Gamble, and when can I use it?
Before your free spins begin, you can gamble to either increase your total spin count or boost the starting value of your chosen Fat Symbol. You decide whether the extra risk matches your stakes.
How often should I expect to land winning combinations with a hit frequency of 1 in 4.31?
You hit a winning cluster roughly once every 4.31 spins on average. With very high volatility, actual results vary significantly over short sessions, so expect longer dry stretches between wins.
Can the Fat Symbol reach maximum size and still grow larger during free spins?
No, the Fat Symbol caps at 7x7, which is the full grid size. Once it reaches 7x7, additional matching symbols still trigger wins but do not expand it further.
