Blockudoku — Play Free Online
Puzzle & BrainBlockudoku is a free block puzzle that blends Sudoku boxes with Tetris-style shapes; place pieces, clear lines and play in your browser.
Blockudoku mixes two puzzle ideas that most people already know: the falling pieces of block games and the 3x3 boxes of Sudoku. Nothing falls, though, and there is no clock. You get a 9x9 grid and a tray of three shapes, and you decide where each one goes. The game ends only when none of the shapes in your tray fits anywhere on the board.
That makes it a calm counterpart to the fast jumpers on Doodle Jump. If a session of Doodle Jump leaves your thumbs tired, this is a game where you can stop and think for as long as you like, then play a few quick placements when you see a clean clear.
How to play
Pick up a shape from the tray and drop it on the grid with the mouse, or drag it with a finger on a phone. Shapes can't be rotated, so you plan around the orientation you are given. When you fill an entire row, an entire column or one of the nine 3x3 boxes, that group clears and frees up space. Clearing several groups with one piece scores more, and chaining clears on consecutive turns builds a combo bonus.
A round is over when the next set of three shapes can't be placed. Each new tray appears only after you have used all three pieces, so you always know what you are working with for the next few moves.
Tips
- Look at all three pieces before placing the first one. The best move often uses the awkward piece first while the board is still open.
- Keep the middle of the grid as open as you can and build up from the edges, so large shapes still have somewhere to land.
- Watch the 3x3 boxes, not just rows and columns. A box is the easiest group to complete by accident and the easiest to forget about.
- Avoid leaving single isolated empty cells. They can only be filled by the smallest pieces, and a few of them will end your run.

If you like thinking ahead rather than reacting, nothing else on the site plays quite like this. Fireboy and Watergirl also rewards planning, but with platforming puzzles you move through in real time. Bloons Tower Defense 2 is another game where placement choices decide everything, though it adds waves and pressure. Helix Jump is a quick reflex game that sits at the opposite end of the pace spectrum.
Blockudoku runs in the browser with nothing to install, which suits short breaks as well as longer sessions. Progress and your best score are kept in your browser on the same device.
