In Schaakmat! you are a 16-year-old girl who has to find a way to win at life. The game is set in the Netherlands in 2009, when your task is to find a cheese that has been shaped like a key. With each key, you have to find a way to win, as oppose to simply winning, as in the other games in this series. There are more than 20 different cheese shapes to find, and it can be difficult to know which one to choose. As you find more and more cheese, it will make it more difficult to win, while also providing a little bit of fun in the meantime.
