Equation · Cages bundles three separate math-puzzle modes in one package: Cage Puzzle (a Sudoku-style grid where cages of cells must solve a printed equation), Equation Match (a tile-swapping grid where equations and answers must be paired up), and Number Crossword (a crossword grid filled in by solving Across/Down equations). Every puzzle in all three modes is generated procedurally at play time — there is no bundled puzzle list. The game features Easy/Medium/Hard difficulty tiers plus a seeded Daily Challenge (shared across all three modes), five selectable board themes, an XP progression system with seven rank tiers, eight achievements, a local best-times leaderboard, an optional Time Attack countdown for Cage Puzzle mode, a Cage Puzzle solved-grid import tool, a configurable hint system, and a full sponsor/ad integration framework — all in a single self-contained HTML5 package.
