Seems you’re into puzzle games so I’ll recommend you that there’s an entire genre of minesweeper clones / inspired games on Steam. Some are straight up clones of the game, others are very similar, and some use the mechanics but twist them around in interesting ways. Good examples are Hexcells, Hexseed, Tametsi, DELETE, and GlobeSweeper. Once you learn the basic mechanics, they’re pretty hard to forget, and a lot of games borrow mechanics from others. When I started DELETE, for instance, the mechanics were a little bit different in some small ways, but I pretty much rocketed through the first dozen levels because of my prior knowledge of how minesweeper works.

I have Trackmania Stadium for that. Going into a full speed server (Only need to steer left or right while constantly press forward) and put some music up.

The flow of the race tracks together with the music is very nice and because no speed control is needed, no need to get into the physics and tracks to enjoy the game.

I can recommend to get into Trackmania when you have more time, the feeling of mastering a hard track is marvellous, but just speeding around is also fun as hell.

Gonna be a bit of an out there recommendation but old Popcap games are available on Steam. They’re good casual games if you don’t mind the lack of challenge. I personally like PvZ, Zuma Deluxe and Feeding Frenzy 2

Counter Strike Surfing. Doesn’t really matter whether you play for 10 minutes or 2 hours :)

Simon Tatham’s Puzzles is an amazing collection of little puzzle games. There a ports for both Android and iOS available as well.

Not so much a game recommendation but a platform, but if you don’t already have a Nintendo switch, it might suit your style.

It lets you suspend any game at whatever point by just going to the Home Screen. You can then put down the switch and leave it for days or even weeks at a time, and then you can just turn the switch back on and pick up exactly where you left off in like 5 seconds.

I’ve been playing heaps of the new Zelda game, whenever I get a spare moment, but also if Nintendo games aren’t your style, nowadays there’s quite a good library of other games for the switch now.

Obviously the suspend feature doesn’t work for multiplayer games though, and to be honest I’ve found multiplayer in general doesn’t work as well on switch as other platforms, but it really is great for quick sessions of single-player games.

Also being portable is a great bonus

Into the Breach would work. You can turn off the game at any point and come back to it, thanks to it saving after every turn. Plays a lot like chess, with different abilities and enemy types to keep things interesting. Highly recommend!
