Operation Cuckoo: As the name suggests, this two-person game revolves around Cuckoos. Both players are cuckoos who have been dropped into a strange nest and want to get all the eggs and young birds of their own color (or the other cuckoo) out of the nest. Operation Cuckoo requires a reverse mindset: you have to ensure that you are left with only your own playing piece as quickly as possible. Where you normally want to hit to win, you now have to be hit.

The board is reminiscent of a chess/checkers board, but with hexagonal boxes that increase the freedom of movement. Pieces must always move forward and must always capture an opponent's piece if possible. If a player captures a piece, his own piece takes that place. The game requires a reverse mindset: you have to ensure that you are left with only your own playing piece as quickly as possible. Where you normally want to hit to win, you now have to be hit.

Operation Cuckoo is played as a best-of-three, where a player must win twice to win the game as a whole. This means the game lasts between 15 and 30 minutes. The game board is double-sided: a standard side and an advanced side. The advanced side usually lasts 30 to 45 minutes.
