The Gasp is a small puzzle game that is a mix of Reverso and Othello. You have a board with 16 cards forming a 4 x 4 square. The goal is to turn over all of them according to one rule: When you point to a card, all 8 of its neighbours are turned over except for it. Can you turn them all over?

There are 6, 8 or 10 moves solutions.
