Eight Crosses is a clever packing puzzle designed by Mike Quigley with nine different challenges of varying difficulty. The goal is to pack the 8 pieces into the frame such that the half-crosses join to make whole crosses.
There are multiple goals, with different solutions for each number of crosses between zero and eight. While it's easy to make four or five full crosses, there are fewer solutions when you attempt to solve for a higher or lower number of crosses. Only one solution exists for zero or eight crosses!
