Tetris 99

Tetris 99 is a competitive puzzle game where you clear lines against 98 other players in real-time matches. Standard Tetris rules apply—rotate falling blocks, complete horizontal lines, survive as long as possible—but cleared lines now send garbage rows to opponents' boards. You pick targeting strategies mid-match: attack players close to losing, counter those sending garbage your way, focus on random opponents, or target badge holders who've already knocked others out. Matches end when one player remains. The multiplayer pressure changes how you prioritize speed versus clean stacking, since a well-timed combo can bury multiple opponents at once. It's Tetris fundamentals with competitive timing decisions layered on top.
