A great way to play Tetris, I picked this up recently and doing a marathon or two is a great way to bide time before a class or whatever, and there's plenty of sidemodes to enjoy.
It's Tetris. Controls well, and you have your Mii doing a funny dance on the bottom screen, its quite enjoyable. Sidemodes are cool but I am basic and enjoy the pleasure of just stacking for a while and making tetrises. Pretty solid, especially as a digital version!

One of the greater tracklists of the guitar heroes and rock bands, and not only are many of the songs fun to play but also just a good way to discover some songs. As usual for GH/RB games I find the multiplayer rather unfriendly, unable to both pick the same part making some songs locked to duels or singleplayer. More goodness nonetheless. I'd recommend this game if you wanted to play some Guitar Hero and you're not a huge Beatles enjoyer.

This is another deckbuilder I can manage. It's not the most complicated game, but there's a lot here to make fun builds off of. Playing in tandem with Balatro and there's a lot to enjoy in both the titles.
The vibe of Cobalt Core is spot-on. The music is excellent, and all of the remarks of the team you choose are hilarious. The game is fun too, I find that there's a lot to get out of this game if you want it to be super hard, and vice versa. Great!
