13. Ruzzle. inspired by the classic board games Boggle and Scrabble

The game is highly social and based on online matches, requiring the player to find an opponent who can be appointed randomly by the system from online users, chosen from a list of friends set by the player, or selected from amongst their Facebook friends. In each round, the player has two minutes to form as many words as possible with the sixteen letters available in the 4×4 grid on the screen. The free version is not really a way to learn but you can use it to improve the languages you know, challenging your friends.
