I like playing Tetris. You could either play 1v1 or battle royale style. It’s pretty frustrating at first but when you get a little good it’s basically second nature

Best ones I know are Jstris or Tetr.io. Jstris is more minimal and good if you don’t like flashy graphics and Tetr.io is basically the opposite of that.

I seem to remember Sakurai saying that this would be the last one. I guess he either doesn’t have much of a say or that it made too much money to pass up on another….

I’ll go for something more simple, but that you still can spend hours on.

Tetris. Jstris if you want a minimalistic version and Tetr.io if you want something more polished.

I also like to play minesweeper, minesweeper.online is the best one I’ve found. I especially like the no-guessing mode which makes the game a lot less frustrating.
