How to play File Recall

1. The cabinet has sixteen closed drawers hiding eight pairs of symbols.
2. Open two drawers per move. If the symbols match, they are filed and stay open.
3. If they don't match, both drawers slam shut again.
4. File all eight pairs. Fewer moves earns a better clerk rating.

Tips

• Open drawers in a fixed order, row by row, so their positions are easier to remember.
• Say the symbols to yourself ("bolt, top left") as you see them.
• When you open a drawer you have seen the partner of, go straight for the pair.
• A perfect game is eight moves, but anything under twelve is excellent.
