It is a collection of many simple games in one app. Each game has very simple rules that are quick to learn, so playing individually or even better as a couple on the same device (smartphone or tablet) is really fun.
Playing parents with children, friends against each other or with someone else and to have a good time together is a great thing. You will have this even if you play alone in single mode.
New games are added on a regular basis, so that the player can look forward to new challenges in various game genres such as skill, memory and attention games at relatively short intervals.
