We tell you who should skip it, too.
Play it if you…
Good fit- Puzzle players who enjoy mathematical abstraction and logic problems
- Players who like building complex solutions from earlier work
- Steam players interested in comparing the efficiency and simplicity of their solutions
Skip it if you…
Saves you a refund- Players seeking a story-driven structure rather than abstract problem solving
- Players who prefer puzzles that do not build on previous solutions
- Players looking for exploration, combat, or character progression
Our take on functional
Instead of treating each puzzle as a separate exercise, functional lets players reuse completed solutions in later problems. That cumulative structure shifts the focus from simply finishing a challenge to constructing increasingly complex logic from earlier work.
What is functional?
functional is a puzzle game about mathematics and abstraction.
It starts with simple mathematical primitives, treating everything as a function and using functions to construct other things. Players solve increasingly complex problems, then reuse earlier solutions as black boxes and building blocks for later ones. Solutions can be compared with those of other players and Steam friends for efficiency and simplicity. Workshop support lets players create levels and share them with the community.
How functional plays
- 01Reusable solutions
- Earlier answers can become building blocks for more complex problems.
- 02Solution comparisons
- Players can compare their results with other players and Steam friends for efficiency and simplicity.
- 03Community level creation
- Workshop support allows players to make levels and share them with the community.
functional compared to similar games
functional focuses on mathematical problems built from reusable functions, with comparisons based on efficiency and simplicity. SpaceChem instead centers on designing factories that transform raw materials into chemical products. Both involve constructing solutions, but their problem-solving systems differ.
