## What is Sudoku?

Take a cozy logic break with colorful grids and butterflies—no numbers. Enjoy Sudoku-style deduction as you find each butterfly's place, make that satisfying final move, and watch them take flight.

ONE MORE BUTTERFLY. ONE SATISFYING FINISH.
Study the colors, mark the cells you can rule out, and work toward the last butterfly. Each placement brings the puzzle closer to completion, followed by a butterfly flight celebration.

SIMPLE RULES. ROOM TO THINK.
• Place one butterfly in each row and column.
• Place one butterfly in each color region.
• Keep butterflies from touching, even diagonally.

The no-touch rule applies to neighboring cells, including diagonal neighbors. Butterflies farther apart may share a diagonal.

START SMALL. THINK BIGGER.
Learn the rules in an interactive tutorial, then follow a level path with boards ranging from 4x4 to 11x11. Smaller grids introduce the ideas; larger boards give you more to untangle.

MAKE YOUR NEXT MOVE CLEAR.
Tap or drag to mark cells as you reason. Need a nudge? Use a hint for a deduction, or a reveal to place a correct butterfly. Tools have limited supplies.

PICK UP WHERE YOU LEFT OFF.
Your progress saves automatically. Each attempt starts with three flowers, and each incorrect butterfly placement costs one. If you run out, retry the same puzzle and take a fresh look.

Find the patterns. Place the butterflies. Enjoy the moment they take flight.
