Functional

Functional is a puzzle game about math and abstraction. You solve problems with mathematical primitives, then reuse your solutions to build increasingly complex logic.

Build with functions

You start with the simplest mathematical primitives. Everything is a function, and functions can be used to build everything else. Previous solutions become black boxes that you can use as building blocks for more complex ones.

Compare solutions

You can compare your solutions with those of other players and your Steam friends, judging them by efficiency and simplicity.

Create levels

You can make your own levels and share them with the community.
