GAMES · IDEAS · UNDERSTANDING

Learn it by playing it.

Games that let you see how things work. They get harder or easier as you play, so you stay in the sweet spot.

Play. See. Understand.

  1. Pick a game.

    Each one is built around a single idea, such as fractions, patterns or cause and effect.

  2. Play it.

    Move things, break things, watch what happens. The idea shows itself.

  3. Keep going.

    The game notices what you find hard and adjusts, so the next level fits you.

WHY MAIN DIAGONAL

The straight line from here to there.

In a matrix, the main diagonal runs corner to corner. It is the plain path through a tangle of numbers. We aim to be that for learning: the shortest path from what you know to what you want to know.

Ideas you can see.

Starting with the basics. More subjects on the way.

  • Numbers

    Fractions, ratios and patterns, as puzzles you can move around.

  • Logic

    Spot the pattern, test the rule, and find where it breaks.

  • Cause and effect

    Change one thing and watch what else moves.

  • Adapts to you

    Stuck? It eases off. Bored? It pushes.

  • See the idea

    Every level ends with what just happened, and why.

  • Starts anywhere

    No setup and no install. Open it and play.

Your first level takes five minutes.
