A Japanese logic puzzle: fill each bold region with numbers. 2,700 puzzles from 5×5 to 7×7 in three difficulty levels.




Suguru is a Japanese number logic puzzle. The grid is divided into regions outlined in bold.
Fill each region with the numbers from 1 up to its size, once each (a 3-cell region gets 1, 2 and 3). The same number can never touch another, not even diagonally. Every puzzle has exactly one solution, reachable by logic alone.
■ 2,700 puzzles in three sizes and three levels
5×5, 6×6 and 7×7 grids, each with 300 easy, 300 normal and 300 hard puzzles. Difficulty is graded by the solving techniques each puzzle needs. Solve a size three times to open the next one.
■ A tutorial that shows you how
On your first launch, an interactive tutorial teaches the two rules one at a time with markers on the board. If you enter a wrong number, the board shows which rule it breaks. The first three puzzles after the tutorial are gentle starter puzzles with a few more empty cells each time.
■ Help when you are stuck
Notes let you jot down candidates, Auto notes fills in every possible number for each empty cell, and Mistake check marks numbers that differ from the solution in red and clears them at once. Numbers that break a rule turn red as soon as you enter them.
■ Come back every day
No time limit, and your progress is saved automatically. Daily missions with coin rewards and a ranking of total cells solved.
