In this game, you will see a gang of rats, a cat, and of course a lot of cheese. The more cheese the rats collect, the bigger payouts you get. So, you need to help them out in order to succeed.

The main game takes place in the dark cellar and the location changes when the Free Spins bonus is triggered. The graphics are crisp and detailed and some nice animations bring fun to the gameplay.

The symbols, they consist of card royals from 10-A, rats icons as well as the Wild and the Bonus symbol. The latter triggers Free Spins and also pays from €4 to €30. The Wild substitutes for all symbols except Bonus and K-Cash symbols. The K-Cash symbol appears on the column which is less than 6 rows in height and is collectible. It can also expand the column’s height up to a maximum of 6 rows.

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:)
