ArrayQuest vs Eye Training｜TraceMaster

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?
