I love Tetris. I used to play this all the time on my phone when I was bored. The multiplayer was also really fun and I was pretty good at it, so I enjoyed playing that once in a while. I like how you could start at any level you wanted to and the level will increase as you play. There's also a variety of music that you could choose from, and while microtransactions were present in the game, there was no need for you to buy them as you could get coins from playing normally
