Winning:: €8
Multiplier: x27
A pretty funny, even a little bit crazy slot. The most shocking part is a cascading mechanics. You won’t many cascading slots from CT.
A slot has pretty cheap symbols, but a series of winning cascades can bring decent wins. But, ofc, free spins round is where the most juice due to additional multipliers. The max multiplier is x100.
The slot rends to go on empty streaks. Even 30-40 fully empty spins are not that rare. Watch your balance and plan bankroll for longer sessions.

Winning:: €17
Multiplier: x56
The slot looks fine and reels are cascading. Indeed there are a lot of dead spins and average wins in the base game from x2 and up to x8. Slim pickings, right? Anyway the slot is marked as high volatility so my goal was to trigger FS round and check it. I've achieved my goal after maybe 300 spins done. I enjoyed the FS roud as it offers a growing multiplier and 15 is a great number of free spins.
I suppose this slot will like players who reserved some balance for a long spinning
