Unit memory

The app contains two games. One is a traditional memory game - the user has to turn two cards and if the picture matches on the cards, he can remove the pair. At the end of the game, the application calculates how many attempts were necessary to find all the pairs. The other game is the development of the first one: on the other sides of the pictures, there are not backsides, but quantities. Each quantity is expressed in two ways, e.g. 1 km and 1000 m. If the two amounts match, the player can remove the pair. The images help to relate the quantity to a phenomenon known from real life, eg. 10 dl = 1l = volume of a milk box. At the end of the game, the application calculates how many attempts were necessary to find all the pairs.
