Lay out a deck of cards face down, flip them over two at a time and keep any matching pairs you find. The game of Concentration is simple, but Memorica adds in surprising twists.

What we love: The incorporation of skill cards in Memorica’s PvP battles to help you locate matching cards quicker. Tap 20 neatly arranged cards to flip them over one by one, then memorise the character on each and find its twin within a 20-second turn. If you come across a character that piques your interest?

Quick tip: Select two skill cards out of four available types before starting a game. With 3 Cards, you can flip over one additional card; Darkness hides the cards you flip from your opponent for a turn; Shuffle resets the positions of their cards, forcing them to remap their board; See Through enables you – and only you – to see the illustration on any card of your choice.
