Sum Grid Logic Puzzle

Matching Rows and Columns to Target Sums

Sum Grid Logic Puzzle presents a grid of numbers. Each row shows a target sum on its right, and each column shows a target sum at the bottom. The goal is to tap or click cells to select or deselect them so that the sum of selected numbers in every row and column equals its target. There is no time limit, and the game provides immediate feedback on whether current selections are on track. Players can experiment with different combinations without penalty.

Reasoning Over Reflexes

Success depends on logical reasoning, not speed. Players eliminate impossible cells and narrow down choices by comparing row and column targets. For example, a row with a small target sum usually means larger numbers in that row can be deselected. Rows or columns with only one possible combination are key starting points. The game encourages exploration and learning through trial and error, with no penalty for wrong selections.

Procedural Puzzles and Gradual Difficulty

Puzzles are generated procedurally, so each session offers a unique set of numbers and targets. Difficulty increases gradually, starting with simple grids and progressing to more complex arrangements that require careful deduction. A progress tracker shows how far you have come. The clean interface and calm color scheme minimize distractions, supporting both short breaks and longer play sessions.

Approaches for New and Experienced Players

Beginners can start with simpler puzzles to build confidence and understand the logic. Focusing on rows or columns with the smallest targets often reveals fewer possible combinations. If stuck, switching to a different row or column can provide new insights. Regular practice improves pattern recognition and logical thinking. The game is designed for puzzle enthusiasts who enjoy thoughtful challenges without time pressure.
