functional is a puzzle game about math and abstraction. Solve problems and reuse your solutions to write ever-more-complex logic.

Start from scratch

Start with the simplest mathematical primitives. Everything is a function, and functions can be used to build everything else.

Solve increasingly complex problems

Use your previous solutions as black boxes, and use them as building blocks to build more complex solutions.

Compare your solutions

Compare your solutions against other players, both in efficiency and simplicity.
