Start with simple puzzles and progress through increasingly complex levels that test your observation, planning, concentration, and spatial reasoning. FOUR PUZZLE MODES 1. Connect Colors Connect dots of the same color without letting the paths cross. Complete every pair and fill the grid to clear the level. The puzzles begin simply, but larger boards require careful planning. 2. Number Path Start from 1 and connect the numbered points in the correct order. Follow the sequence, choose the right route, and complete each board without missing a number. 3. One-Line Puzzle Connect every required point with one continuous stroke. Study the shape before you begin and find a route that completes the entire pattern without lifting your finger. 4. Fill Every Cell Start from the marked position and draw a route through every cell. Plan each move carefully so that no space is left uncovered.
