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.
About Wood Block Sudoku
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.
Inside Wood Block Sudoku: what we checked
The numbers below come from Wood Block Sudoku's own source code, and the screenshots are from our own test run of the game (20 October 2026).
- The board is 9 × 9 with nine 3 × 3 boxes, like a Sudoku grid. A full row, a full column or a full 3 × 3 box clears, and one piece can complete several at once.
- You are always given three pieces at a time, and pieces cannot be rotated. A new set of three arrives only once all three are placed.
- Placing a piece scores one point per block. Each cleared line or box scores 100 on top, and clearing several with one piece adds 150 for each extra one, so a double clear is 100 + 100 + 150 = 350.
- Clearing on consecutive placements builds a streak that adds 60 per step after the first, and one placement without a clear resets it.
- Harder pieces are held back until you earn them: the set starts with singles, dominoes, 3-in-a-lines and the 2 × 2 square, adds 4-in-a-lines, small corners, L and T pieces from 400 points, and long 5-in-a-lines, S and Z shapes and 2 × 3 blocks from 1,500. The big L pieces and the 3 × 3 block wait until 4,000.
- The game ends when none of the three pieces fits anywhere. The Hint key (H) moves the cursor to a spot where a piece fits, and the unfinished game and your best score are kept in this browser.

How to play Wood Block Sudoku
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.
Controls
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.
Tips & tricks
- Three kinds of line clear at once, rows, columns and 3x3 boxes, so a single piece dropped in a corner box can finish a row and a column too.
- Set up two or three clears to trigger together for a combo bonus that dwarfs single clears.
- Place the big awkward pieces, the 3x3 square and the long planks, while you still have open space for them.
- Keep one 3x3 box mostly empty as a parking spot so a stray large piece always has somewhere to go.
