Blockivo

The board is an 8×8 grid. You drag shapes onto empty spaces, and every full row or column you complete disappears and scores points. Because the grid is small, planning where each shape goes matters more than you might expect.

Complete a full row or column and it disappears, giving you points. Your aim is to score as many as you can and climb the global leaderboard, so keep your gaps tidy and set up clears before the board fills up.

Line Breaker is a booster for when the board gets too crowded. It removes two rows or columns that you select, which frees up space for the next set of shapes. Save it for when you're boxed in.

Yes. Undo lets you take back your last move, which is handy when you drop a shape in the wrong spot. It sits alongside Line Breaker as a way to get out of a tight spot.

You get three shapes at a time. Once you've placed all three on the board, a new set appears. Check all three before committing to the first, because where one goes decides where the others can fit.

Yes, it's a one-player game. You're playing against the board and the global leaderboard rather than a live opponent, so you can focus entirely on your own grid and your own plan.

It's free and plays right in your browser on desktop. There's no download. Ilneo games made it, and it's built in portrait orientation. Open the page, drag a shape, and you're playing.
