Casa Memo is a flexible Concentration-type game for one to four players. Play against time or compete against your friends or your family. Your task is to find the twins behind windows or flip cards and find more matches than your opponents. In single player mode you'll need to be fast and need as few tries as possible to reach a place in the highscore list. In this version you choose from numerous themes: windows of a house, fishes in an aquarium, classic picture cards, colors and forms, letters and numbers, flags on a globe, a picture galery, animals or flowers and more, all of them coming with friendly graphics. You may even create your own cardsets and use from inside the program. Board size can be varied in up to 6 steps (depending on screen resolution). Vary the game by changing visibility time between 0.1 and 5 seconds, selecting whether found pairs should be removed or not and raise the game's difficulty by setting wrong tiles to swap places. Events are accompanied by optional sound effects and a background music will be played if wished.
