Sumpaz: Math & Logic Puzzle

Sumpaz is a calm number logic puzzle that helps you think, not guess. Place the numbers and use the cage sums as clues to reason your way to the answer. Two simple rules • Fill each row and column with 1–N (1–5 on a 5×5 board) • Each bold-outlined "cage" adds up to the small number in its corner Just numbers and a grid — no reading required. Stop any time • Leaving the puzzle pauses the timer and keeps your progress • Come back to the same puzzle and continue, pencil marks and all Something new every day • A daily set of three puzzles (Easy, Medium, Hard) • The longer your streak, the more XP you earn • Streak protection covers a day off Plenty to solve • Sizes 5×5 to 8×8, three difficulties, 60 puzzles each — 720 in all • Leveling up opens new puzzles and color themes • Solved puzzles keep your time and XP as a record • Notes, hints, and undo to keep it smooth Made to feel good • A quiet, minimal design — no characters, no clutter • Play offline • A one-time Full Unlock removes ads and opens larger boards Every puzzle is built to be solved by logic alone, with no guessing. Great for a few quiet minutes on the commute or before bed.
