For me it was minesweeper clones. I got frustrated one day and decided to learn how to be good at minesweeper. After beating the medium and large boards a couple times I looked on Steam for minesweeper versions, and turns out there’s a whole genre of clones. Some of them are direct clones of the game, while others are very heavily inspired by minesweeper. The two best I played were Hexcells and Tametsi. Hexcells is stylish and is only hexagons (as opposed to the minesweeper squares), while Tametsi has squares, rectangles, and hexagons and is a lot more barebones. However I found Tametsi to be much harder. There were some levels on there that took me an entire day, and I think there’s like 500 levels. 150 levels
Sounds like hexagons would be easier as you can only have up to 6 adjacent tiles as opposed to 8 with squares.
Besides that, what do they do differently?
It has a lot of different mechanics. It’s more of a combination of minesweeper with nonograms (aka picross) where the idea is that there is that you can solve all puzzles without any guessing. Check out the Steam page
Well hexagons are the bestagons
