Good game, needs battery optimization
This is an excellent brain-teaser game. I like that there are three levels you can choose from depending on how challenging you want it to be. The expert level is indeed difficult.
The only reason I docked a star is that it needs battery optimization. It drains faster than a card game should. My phone gets a tad warm if I play too many games in a row. It’s tolerable, but that issue does affect how long I choose to play.
I do appreciate the fair price with no ads or IAP.
I recommend this solo game if you want something that can be relaxing but still challenging.
