About this game

ORTHO is a relaxing 3D cube puzzle game that challenges your spatial logic, perspective, and imagination.

Study 2D projections, then build a 3D structure that matches both views. Place and stack cubes, rotate the world, explore different perspectives, and solve elegant spatial puzzles from every angle.

THINK IN 3D

Every cube can change both projections at once. Train your spatial reasoning as you solve perspective puzzles, geometry challenges, and mind-bending brain teasers.

There is no single hidden shape to copy. Different 3D structures can produce the same projections, so every puzzle can have multiple valid solutions. Find your own path — then see if you can build it with fewer cubes to win extra star.

100 HANDCRAFTED LOGIC PUZZLES

Progress through 100 carefully designed levels, from simple cube puzzles to advanced challenges involving depth, floating structures, negative space, temporary scaffolding, ambiguous perspectives, and multi-layer spatial reasoning.

Complete each puzzle to unlock the next.

FIND THE OPTIMAL SOLUTION

Matching both projections solves the puzzle. But true mastery means finding the most efficient structure.

Refine your solution, remove unnecessary cubes, and reach the theoretical minimum to earn an Optimal Solution.
