1010 Fish Blocks

Drop fish-shaped blocks into a 10x10 grid and clear full lines before the board swallows you whole.

Ten by ten. That's the whole battlefield. You get three fishy shapes at a time, and you have to slot them somewhere—anywhere—on the grid. Fill an entire row or column and it vanishes, giving you more breathing room. The catch? There's no rotation. What you see is what you place, so those awkward L-shaped fish and chunky squares start feeling personal after a while. I kept misjudging the gaps—like thinking a skinny vertical fish would fit next to a leftover corner piece, only to realize I'd blocked off the only spot that could have saved me. The art style is bright and bubbly, with little fins and tails instead of plain blocks, which makes the board look more like a weird aquarium than a spreadsheet. It's the kind of puzzle where you can coast for minutes, then suddenly every piece is too big and you're praying for a single line clear. Unlike Tetris, nothing falls or rotates. You control the pace. That sounds relaxing—and it is, until you glance at the three upcoming pieces and realize none of them fit anywhere. High scores get addicting fast. One run I had a beautiful corner setup, then a five-long horizontal fish swam into my queue and I had to dump it on a row that didn't clear—three turns later I was out. I'd tell myself one more game, then suddenly I'm 40 minutes deep trying to beat my old grid. If you like spatial puzzles that punish greedy placement, this one scratches that itch.

Use mouse or touchscreen to play this game.

Keep at least one row or column almost clear so you always have a fallback spot.
