he algorithms from your CS textbook — now playable. Find the maximum submatrix and optimal path in every grid. Free to download and play!
Real computer science problems. Turned into a game.
ArrayQuest transforms two classic algorithms — Maximum Submatrix and Maximum Path Sum —
into addictive puzzles you can play anywhere. Use logic, intuition, and strategy
to find the optimal solution hidden inside every grid.
---- Two Game Modes ----
▶ Max Submatrix
Drag across the grid to select a rectangle with the highest total sum.
Pack in as many positive numbers (blue) as you can, and cut out the negatives (red).
Grids grow larger as you advance — your thinking has to grow with them.
▶ Max Path Sum
Slide your finger from the top-left cell to the bottom-right, tracing the path
with the maximum sum. You can only move right or down — deceptively simple,
strategically deep. Reach the goal and the game judges instantly.
---- Features ----
• Stage System: grids get bigger, challenges get sharper
• Scoreboard: Record your clear times and chase your personal best
• Rules Guide: Clear explanations for each mode, with worked examples
• Swipe Input: Smooth, intuitive gesture controls throughout
Can you find the optimal solution?
