Zink

Need a mental break? Enjoy mental exercise that isn't painful? Want to tune out but not be a passive potato? This is the game for you. Take a break from whatever, go up a stage or two in Zink, the get back at whatever is was a little fresher. Nothing too deep here, but not shallow either. It's probably worth full price if you need a lot of breaks at your screen and fresh air isn't a thing you like. If the devs keep adding and tweaking it can only get better. Also it keeps telling me I'm a genius

Good game, fell asleep while playing (in a good way)

Very good puzzle game with quite a few tough puzzles near the end. Almost 2,000 levels too so there is plenty of content here for the price.

Pretty fun.

It looks simple and it starts easy. But it quickly starts to exercise the little grey cells to become quite challenging in a very relaxed manner.

A simple relaxing puzzle game. It game out when I had bad anxiety, and was struggling to get into anything else. The puzzles get pretty devious, but you can always brute force your way if you get stuck by just trying all the options, so being stuck can't last longer than the full decision tree for the level. It's very reasonably priced, as well, which is rare to see these days.
