Bananagrams is a Scrabble-like multiplayer game based on the physical game Bananagrams. The iPhone version allows both single player gameplay, as well as online multiplayer which more closely matches the real world experience.
Each player has their own set of tiles to work with and must build their own word tree, using crossword/Scrabble rules. Once all of a player's current tiles are in a word tree they peel, and each player must draw another tile from the shared bunch of remaining tiles. Play continues until all tiles in the bunch are gone, and at that point the first player to get all of their tiles into words wins by calling Bananas.
The iPhone version also links to the players playing on Facebook and allows earning of rewards and new tiles or game boards.
