Play Polarium Online

Polarium is one of those DS puzzle games that looks simple at first—blocks drop, you flip them between black and white to clear full lines, just like Tetris but with a twist. But here’s the catch: you don’t just tap blocks one by one. You can drag the stylus across the screen to flip a whole row at once, which feels way more satisfying than it sounds.

Then there’s puzzle mode, where the blocks aren’t falling—they’re just sitting there, taunting you. Your job is to clear the entire screen in one smooth stylus swipe, flipping blocks so every horizontal line matches. Sounds easy until you hit the later puzzles, which will absolutely wreck your brain.

But the real fun is multiplayer. You and a friend battle on separate screens, scrambling cleared lines and sending them to each other’s board. It gets chaotic fast, especially since you only need one cartridge to play. And if your friend doesn’t own the game? No problem—they can still try a demo version. It’s the kind of game that turns casual matches into intense, stylus-flipping showdowns.
