Pie Rats
Pie Rats is a 6x7 cluster pays slot with tumbles, and 4 bonuses in 1,000 spins is a decent hit rate. My best win was 74.8x in a bonus, but the base game never really got going, the artwork wasn’t for me, and the high paying symbols look too alike. Giving each character its own skill that can lead to big multipliers would make a big difference, and with some fine tuning the game has good potential. Not approved, but Keystone stays on my radar.

Day 47 - Pie Rats- Slot Review
Pie Rats is a 6x7 cluster pays slot from Keystone Studios, released this year. It’s the studio’s second game, and the third is already in the works. RTP is 96.00% and the max win is 50,000x.
You win by landing clusters of matching symbols anywhere on the grid, and every win tumbles, so new symbols drop in and can chain into more wins. Wilds help you build clusters, and the Key and Chest are a pair of symbols that work together when they land next to each other. Land scatters (the compass) to trigger free spins, which start at 5 spins plus extras for each scatter. The Cannon and Wild Bomb show up in free spins.
Plan for winning: keep the tumbles going in the base game and land the compass scatters for the free spins, because that’s where the Cannon and Wild Bomb can turn a few clusters into a big multiplier.
In my 1,000 spins a total of 4 regular bonuses triggered and no super bonus. That’s a decent hit rate for a slot like this. My biggest multiplier of the day was 74.8x in a bonus round, and I didn’t see a decent win in the base game. I did get to see most of the core features and how they work in the base game.
The Key and Chest felt a bit overlooked, though. They’re just two symbols you expect to land next to each other, and there are no animations or teasing moments built around them to make it more fun.
The artwork wasn’t my cup of tea, and the high paying symbols look a bit too similar to each other.
Most importantly, I’d add more story behind each high paying symbol/character. If they had different skills that could potentially lead to big multipliers, the base game would be a lot more fun.
We ended the session in a loss.
1000 Spins NOT APPROVED, but Keystone is on my radar for their next releases.
