How to play & controls

Choose a row, then how many nodes to remove. Click a crystal to select it and all crystals to its right. Review your move and press Extract.

Use A–E to select a row, ← / → or − / + to change the count, and Enter to extract. Esc clears your selection. Ctrl/⌘ Z undoes a turn.

The original rule is last node loses (misère Nim). You can also choose last node wins in New game. The quantum theme is visual; the rules are classic Nim.

Rematch keeps the setup and scores, and alternates who starts. New game resets scores. Hints and the coach are optional.
