I have a few games that I am playing at the moment, but a lot of them require at least some time commitment once you start a round. I’d like something that I can start now and maybe finish later. Something on the line of Solitaire or https://mergetin.com/ .
Mechabellum.
Very easy to pick up auto-battler. Short matches, but quite a lot of tactical depth.
Another easy auto-battler would be Super auto pets. Easy to play on short breaks.
