TapDoku

Sudoku meets Minesweeper in this unique puzzle hybrid! Use logical deduction to reveal safe cells and flag hidden bombs before they explode.

What is TapDoku?

TapDoku combines the strategic cell-revealing of Minesweeper with the number logic of Sudoku. Every puzzle is a valid Sudoku grid, but there's a catch: all 1s are bombs! Your mission: reveal all safe cells and flag all bombs without making a wrong move.

The Twist: Use Sudoku logic to figure out where the 1s are hiding, then flag them before you accidentally tap one!

Pure Logic, No Guessing: Every puzzle has a unique solution and is solvable using pure logical deduction. Our puzzle engine uses 26+ Sudoku solving strategies — from basic singles to advanced techniques like X-Wing and Swordfish — ensuring every move can be reasoned out.
