MEGA Bloks Memory Builder is a memory and matching game using 20 plastic maxi Mega Bloks in 4 different colours with animal pictures on them. These blocks are hidden randomly in a 'field' - a cardboard insert within the game box. Players can't see the animals, only the colored tops of the Mega Bloks. Each player takes one of four double-sided 'barn' cards showing a set of animals (four animals on each side, in four different colours). The cards have insert holes for a white Mega Bloks stand. Players then take turns at pulling an animal block from the field, trying to be the first to find the four animals on their card. The first player to match all four animals on their barn card wins. The game components are easy for small children to manage and the game is fun and challenging enough to hold interest. The double-sided cards allow some variety and replayability.
