Math Games That Make Numbers Visible

See maths happen: watch a bell curve build itself from a thousand marbles, fold paper to the Moon, count to a googol, find musical ratios with pendulums.

4 games, all free, no download and no sign-up, on phones and computers.

1. Drop a Thousand Marbles: A real-physics Galton board: chance at every peg, certainty in the pile.
2. Snip & Unfold: Cut a folded wedge of paper and unfold a snowflake with real six-fold symmetry. Save it, or match the daily pattern.
3. Fold It to the Moon: Guess how many times you’d have to fold a sheet of paper to reach the Moon. Then fold it and find out.
4. Count to a Googol: Count by ones, then tens, then double, then square. Pass the atoms in the universe on the way to a googol.
