Fun Megaways game with an upside.
Symbols are cheap, but due to megaways mechanics slot can pay decently even on the base game. But ofc FS is where the juice is. Multipliers in the free games can help u massively.
I like a sort of absurd atmosphere in the slot with all those rats&cats. It’s easy to sink in the gaming process and lose the control over the balance. Don’t do that. Slot is volatile and down streaks here can be harsh. Buy Bonus is there, not sure if worth buying if slot cold.

Rumble rats is about funny rats and cat struggles. This is a megaways slot that offers payouts over 10x in the base game and that's nice. As for bonuses it has respins round with cash symbols. It triggers quite closely and hits are over x40. What I appreciated also is the quick spin option because not all games offer it. I definitely enjoyed playing this slot overall. It has all the essentials to make the game funny and bring decent rewards. Hope you have the same positive feedback:)
