Grid Pulse is a 6×6 logic puzzle — fill the grid so every row and column contains 1–6 exactly once, a Sudoku variant without the 3×3 blocks.
Choose Daily mode to play the same puzzle as everyone else and compare your score, or Free Play for an infinite variety of grids. Three difficulty levels (Easy, Medium, Hard) with pressure tiles: countdown cells that penalize you if left empty too long.
Score is based on speed and accuracy. Earn medals from Bronze to Perfect.
