+summary: Reorder tiles to fit a square
+description: |
+  Each square piece has a number on each side. Position the pieces on the left
+  side of the board so that the same numbers are next to each other. If the
+  numbers don't match, you can't put the piece there. Move quickly: you're
+  being timed!
+
+  You can make the game easier or harder by changing the size of the board.
