5 Grid Solitaire Game

Follows along similar lines to Double Take, where you have red and blue pieces and the aim is to change them all to blanks. Even the symbols are the same, but that's where the similarity ends. There's one board in the centre and four on the edges of your screen. You can swap any symbol with another of the same colour provided they are on the same square of the different boards and one of the two is on the central board. However, you cannot swap a red symbol onto a board which already has its blue partner (and vice versa). Swap pieces so there's two of the same symbol (and colour) on the same board and you eliminate both pieces. Sound complicated? It is!
