Every region has a target sum. Swap tiles until every region matches at once. That is Gridsum — a number puzzle built on pure logic. No timer. No lives. No luck. The board is fully knowable and every solution is reachable through arithmetic and planning alone. HOW IT WORKS The grid is divided into colored regions. Each region contains numbered tiles and a target sum. Swap any two tiles and watch the totals shift in real time. Find the arrangement where every region simultaneously hits its target — puzzle solved. Gridsum starts with a simple 2×2 grid and two regions. As difficulty climbs, the challenge deepens: 3×3 and 4×4 grids, irregular region shapes, and tiles that belong to two regions at once — where a single swap changes two totals simultaneously. Every puzzle is solvable through logic. No guessing required. HUNDREDS OF HANDCRAFTED LEVELS Work through the difficulty tiers: Tutorial, Beginner, Apprentice, Intermediate, Advanced, Expert, Veteran, and Pro, Master, and Grandmaster. Each level is rated by move count. Solve within the target — no hints, no resets — to earn a PERFECT badge alongside your stars. Every level tracks your personal best time and move count. See exactly how much you've improved. DAILY CHALLENGE A new arithmetic puzzle drops every day, seeded by the date.
