Touch-based fractions learning game for tablets & phones

Diffission is a touch-based fractions learning game developed by Filament Games for web browsers, tablets, and mobile devices. Players solve procedurally generated puzzles by slicing shapes into equal parts to create specific fractions through intuitive, gesture-driven play. This interactive experience uses geometric manipulation to help players master fractional concepts through endless, procedurally generated challenges across multiple digital platforms.

Learning focus

Fraction Partitioning, Numerical Equivalence, Visual-Spatial Math, Geometric Reasoning

GAME FEATURES

Slice shapes to form fractions

Break whole shapes into equal parts to match target fractions.

Solve procedurally generated puzzles

Engage with endlessly varied fraction challenges.

Manipulate blocks through touch gestures

Swap, dissolve, and divide shapes using intuitive controls.

Unlock new trials through progression

Collect diamonds to access increasingly complex challenges.

Core Learning Outcomes:

  • Reason abstractly and quantitatively about fractions
  • Partition shapes into equal areas and express each part as a unit fraction
  • Explain fraction equivalence in specific cases
  • Compare fractions by reasoning about relative size
Why This Project Matters

Fractions are a foundational math concept that often benefits from visual and tactile exploration. Diffission supports conceptual understanding by letting learners manipulate parts of a whole directly, reinforcing fraction reasoning through repeated, hands-on practice.

Awards & Recognition

We admit it—math wasn’t exactly our strong suit in school. But fractions would have made a lot more sense if we’d had Diffission. This educational puzzler elegantly introduces the mechanics of slicing up blocks to equal target fractions, then gradually turns up the challenge. Before we knew it, we were learning about dividing whole numbers in a fun new way.
