Game Overview
Arithmetic becomes a movable part of the puzzle in E9uations, a compact single-player brain teaser that reshapes Sokoban’s box-pushing logic into something far more numerical. Rather than controlling a character, you guide an equals sign across carefully arranged grids filled with digits, operators, and targets. The mood stays clean, calm, and methodical, but the solutions can become satisfyingly devious once every move changes the mathematical possibilities around you. It is less about racing through sums and more about seeing how a board can be reorganized into the one equation that works.
Each level asks you to position the equals sign so numbers and operations form a valid calculation, which then resolves automatically and produces a result on the other side. Matching that value with an octagonal target removes both from the board, gradually clearing the route to victory. Addition, subtraction, multiplication, and division are the only tools involved, so success relies on spatial planning, order of operations, and avoiding irreversible pushes rather than advanced mathematics. More than 160 handcrafted puzzles span several themed chapters, and the structure allows you to move between easier and tougher challenges instead of stalling on a single roadblock. Unlimited undo makes experimentation painless, while optional hints present stripped-back versions of a puzzle to nudge your thinking without handing over the answer.
What separates E9uations from ordinary math games is that the arithmetic is inseparable from movement: every equation is also a positioning problem. Its minimalist presentation keeps attention on the board, allowing the gradual introduction of new arrangements and interactions to carry the challenge. Controller support suits relaxed sofa play, though the deliberate, grid-based design is equally at home with mouse or keyboard. Fans of Sokoban, Baba Is You, or other logic puzzles built around small spaces and big consequences should find plenty to enjoy, while newcomers benefit from the approachable sums and generous undo system.
