Sudokuel: Multiplayer Sudoku

Sudoku, but someone is playing against you.

Sudokuel is a multiplayer sudoku game where two players share one grid and only one of them can see the answer. Play sudoku with friends in real-time 1v1 duels, or take on the AI any time.

TWO ROLES, ONE GRID

As the SOLVER, you fill the grid against the clock with four hearts to lose. As the SETTER, you can see the solution, and you hide traps in the cells you think your opponent will reach next. Every trap that lands costs a heart. Every trap that misses is a wasted guess.

It is the same sudoku you know, played as a duel.
