Drag and drop the Greek letters in the grid so that each letter appears exactly once in each row, column and main diagonals. This game is updated 4 times a day: 00:00, 12:00, 16:00, and 20:00.
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.
