How it works

  1. Step 1

    Play

    Fill in the blank. Short puzzles, instant feedback, no streak pressure.

  2. Step 2

    The graph remembers

    Every answer updates your mastery of each concept in a knowledge graph.

  3. Step 3

    The Coach picks your next one

    It walks the graph to your weakest link, then shows you "Why this?".

  4. Step 4

    Make your own

    Turn your notes or a short prompt into new puzzles. Review them, then keep them or share by e-mail.

Never a mystery recommendation

Every pick comes with its reasoning: the weak spot, how concepts connect, and the puzzle that fixes it. Open “Why this?” any time.

Example: the Coach picked a puzzle about B-trees. Here is the reason, step by step.
