What is Sudoku Block Puzzle?
Sudoku Block Puzzle is a casual puzzle game on a 9x9 grid. Each turn you get a set of block shapes and must place them somewhere on the board. When a full horizontal line, vertical line, or 3x3 cube is completed, those tiles clear and you earn points. The challenge grows as the board fills up and fewer gaps remain for the incoming pieces. There is no time limit, so every placement is a deliberate choice.
How to place blocks
Controls are minimal: click and drag blocks onto the grid with the left mouse button. On touch devices, tap and drag with your finger. There are no rotations or flips, so the shape you see is the shape you place.
| Action | Control |
|---|---|
| Pick up a block | Click and hold (left mouse button) |
| Place a block | Drag to a valid cell and release |
| Touch devices | Tap and drag with one finger |
Scoring, combos, and streaks
Points come from clearing tiles, but the multiplier system is where the real scores come from. Landing a combo or keeping a streak alive can push your total far above a basic clear.
| Scoring event | How it works |
|---|---|
| Line clear | Complete a full row or column to remove those tiles |
| Cube clear | Fill a 3x3 square to clear all 9 cells at once |
| Combo | Clear multiple lines or cubes in a single block placement |
| Streak | Clear tiles on consecutive placements for bonus points |
Daily challenges and trophies
Alongside the standard endless mode, the game offers daily challenges that refresh every 24 hours. Complete a daily task and you earn a unique trophy for that day. Trophies do not carry over, so returning each day is the only way to collect them all. It is a low-pressure reason to come back without any energy timers or paywalls.
Tips for keeping the board alive
- Place L-shapes and T-shapes near corners early; they are hardest to fit later when space shrinks.
- Aim to clear a 3x3 cube and a full line in the same move for a combo multiplier.
- Look at all three incoming pieces before placing any of them. The order matters.
- Keep at least one open column and one open row at all times as escape routes.
- If no combo is available, prioritize freeing the most congested area of the board.
