(An official convention game $8.90 and I created for the 2016 NPL Convention. These are, respectively, the original team version of Phases 1 and 2, a solitaire version of Phases 1 and 2 that may be more suitable for solving at home, and the original version of Phase 3. Do some version of Phases 1 and 2 before looking at Phase 3.)
