Except instead of pies, bowling balls. Or anvils.

Shattered Pixel Dungeon.

Infinitely replayable procedurally generated roguelike that is hard but fun to master, and a blast to play. It’s been on my phone for five years now and I still go back to it.

Totally offline, totally ad free, and still receiving active updates from the single developer.

It’s also got a pretty robust community.
