I would like to introduce you to a very nice game I discovered a few months ago, its name is Shapez.io and is a "factory" game, a genre popularized by the famous game Factorio. In this game you will have to extract shapes and colors and rework the shapez, mix colors and mix the whole thing together to produce wanted pieces.
The gameplay is very cool, the early game is an introduction to the game mechanics, you can extract shapes, cut them rotate pieces, merge conveys belts into one, paint shapes etc... and logic circuits!
In those games, you will have to learn how to make efficient factories and mostly "tile-able" installations. A tile-able setup means that if you copy a setup and paste it next to it, it will be bigger and functional, meaning you can extend it to infinity (except that the input conveyors will starve at some point).
It can be quite addictive to improve your setups over and over. This game is non violent and doesn't require any reflex but you need to think. You can't loose, it's between a puzzle and a management game.
Where to get it
On OpenBSD since version 6.9 (not released yet when I publish this) you can install the package shapezio and find a launcher in your desktop environment Game menu.
I also compiled a web version that you can play in your web browser (I discourage using Firefox due to performance..) without installing it, it's legal because the game is open source :)
The game is also sold on Steam, pre-compiled and ready to run, if you prefer it, it's also a nice way to support the developer.
