CISRA Puzzle Competition 2012 - Hints

2D. Danger Looms

• How many crossword grids should there be? How are we going to fabricate them? Scissors and tape will help.
• The grids will be constrained by: (a) the usual conventions of crossword grid numbering and rotational symmetry, (b) fitting the clued words in to the right grids.
• Several of the clue words give hints to the right process for forming the grids. The pieces provided form two grids, one on each side, with half the squares hidden inside the construction. Undo it and do it again in a different way to find the other two grids.
