I mentioned I've been playing Mr. Driller in another topic, and it's not a
brain teaser puzzle game that deals with logic puzzles like Baba Is You, it's a more Tetris-like actiony puzzle game. The reason it's so addicting is because you can tangibly feel yourself getting better the more you play it, in a way that you kinda don't with other games. In other games, you make a lot of progress through scenario memorization and trial and error, but with these kind of quick-thinking action puzzle games, you get better by training your brain to think differently. You're able to read the board faster and recognize patterns quicker, and think more and more steps ahead. You're starting from scratch with a randomzied play field each time, but you're playing for longer and getting higher scores because your brain's getting more adept at the task.
One thing that's super satsifying about these Tetris kind of games, is when you have a long play session, and feel like you're hitting a wall and you're not getting any better. Then you go to sleep, and the next day you pick it up again... and crush your old score! There's something about just "sleeping on it" that really helps your brain lock the practice you've done, and you can see it in a super tangible way when you see your scores go up. It's all very addicting seeing your progress day by day!
As for "are we suckers"... well, yes, pretty much

With this particular type of game, we're not really learning anything meaningful or becoming better at a task that has any actual application... but it does feel good anyway!
