Sudoku Flow is pure sudoku — free to start, ad-free, thought-provoking and calming. A minimal board, a number puzzle with nothing between you and the logic. Optimized for iPad and iPhone Duo. Just you, the grid, and the quiet pleasure of thinking clearly. DEEP GAMEPLAY Over 250 puzzles, each solvable, and with increasing difficulty. Hints to help you if you get stuck. Six difficulty packs run from Starter to Master. A NEW PUZZLE EVERY DAY Come back for a free daily sudoku. Keep a streak going if you like — it's a quiet counter, never a guilt trip.

The same calm game, with more room to think.
