KLOAK: The Undercover Strategy Game

On your turn, move any piece on the board one space in any direction. For the small pieces, the adjacent space must be open to move. For the big pieces, you can move onto any open adjacent space or onto any adjacent space with a small piece. As small pieces are moved and covered (kloaked), you have to remember where they are. Be first to align two sets of three small pieces of the same color and win! —description from the designer
