Find the pattern. Plan your moves. Bring the entire matrix to zero. Sum Of None is a calm number puzzle built around a simple rule: tap a tile, and that tile and every touching neighbor decrease by one. The challenge is knowing which moves to make—and in what order—without leaving isolated numbers behind. Every matrix can be solved through observation, planning, and a little experimentation. There are no timers and no pressure. Work at your own pace, undo mistakes, reset the board, and return to unfinished games whenever you’re ready. FEATURES • Three difficulty levels: Easy, Medium, and Hard • Guided Practice that teaches the core pattern • A new Daily Matrix based on the current date • Automatic saving for unfinished games • Undo and reset controls • A private, on-device personal leaderboard • Optional sharing after completing a matrix • No account required • No advertisements or tracking Whether you want a quick daily brain exercise or a more demanding logic challenge, Sum Of None offers a focused puzzle experience where every move matters. Can you reduce it all to zero?
