Proof Fidget

ProofFidget is a puzzle-driven way to learn the feel of doing math: not by memorizing procedures, but by making correct moves, one step at a time, until a proof truly holds together.

Each puzzle gives you a clear goal and a partially-complete derivation. You spin the wheel to choose your next move, then commit to a step and watch the proof line up. If you’re right, you progress; if you’re wrong, you learn quickly why it didn’t fit. The result is a tight feedback loop that makes abstract ideas concrete and surprisingly fun.

You’ll work across a growing set of subjects, including:

Logic and proof techniques: build confidence with implication, contradiction, and structured reasoning.
Algebra: make valid transformations while keeping equations balanced, supported by visual “balance scale” diagrams.
Number theory: practice modular arithmetic, divisibility, and gcd-style reasoning with intuitive visuals.
Geometry and beyond: use diagrams to ground symbolic steps in something you can see.
ProofFidget is designed for short, satisfying sessions, but it also rewards deeper play: you start noticing patterns, choosing steps for the right reasons, and developing proof instincts that transfer to real coursework and problem-solving.

If you’ve ever thought “I understand the formula, but I don’t understand why,” ProofFidget is built for that moment.
