Edit: 3/23/22 Avoid the ads if you play this. The recent addition of bingo tower operates like a virus, automatically opening your phone's store and trying to install itself. Can not recommend until this is fixed. This Is a classic cookie clicker style time waster. With a bunch of hidden mechanics that keep the game pretty dynamic, and is one of the few that doesn't bombard you with ads. Push button, get chickens, buy upgrades, repeat.
