Tips

If this is your first time playing, choose the "Very Easy" grid so that you can understand the rules clearly;

Start by looking at the grid and observing which letter appears more often. It's very likely that you'll use it right away;

Logic strategies such as "Naked Pairs" and "Hidden Pairs", that are usually needed to solve Sudoku puzzles, can also be used on this game (see our Sudoku Guide).

About

To make the game more interesting, we used some letters from the Greek alphabet. The letters we chose are: Δ (Delta), Θ (Theta), Λ (Lambda), Ξ (Csi), Π (Pi), Σ (Sigma), Φ (Phi), Ψ (Psi) e Ω (Omega).

This puzzle was originally created by the Russian Leonid Mochalov.
