Drag carved wooden pieces onto a 9x9 grid, then fill a whole row, column, or 3x3 box to clear it. No timer, no luck. Just you and a board that slowly runs out of room.
Wood Block Sudoku is the warm, low-stress block puzzle that quietly sharpens into a real test of foresight. You get three hand-carved wooden pieces at a time: anything from a single cube to a long plank, an L, an S, or that dreaded 3x3 square. Drag each one onto a nine-by-nine grid. The sudoku twist is what makes it sing. A placement clears any line that fills up, and lines come in three flavours at once, full rows, full columns, and full 3x3 boxes, so one clever drop can wipe out several at the same time for a fat combo bonus. Keep clearing on back-to-back placements and a streak multiplier stacks right on top. No clock, no randomness you can't see coming. The only pressure is space. Every piece you place eats into the board, and the game ends the moment none of your three pieces fits anywhere. It all runs on a cozy wood-grain-on-dark look with a satisfying snap each time a piece locks home. Easy to start. Genuinely hard to keep alive.
Drag one of the three wooden pieces from the tray onto the 9x9 board. A piece only drops where all of its cells land on empty squares, so a green ghost preview means it fits and a red one means it won't. Completing a full row, a full column, or a full 3x3 box clears those squares and scores points, and clearing more than one at once earns a combo bonus. Chain clears on consecutive placements to build a streak multiplier. Use all three pieces and three fresh ones appear. The game ends when none of your current pieces can fit anywhere on the board.
Click or tap and drag a piece from the tray onto the board, then release to drop it; on touch the piece lifts above your fingertip so you can see where it lands. P pauses, M mutes. Your best score and current board save automatically.
