I've never, in my life, paid money for a game on a cell phone. Until Alphabear
It's a scrabble game, essentially, but you have to spell strategically because every time you clear a letter off the board you get a cute bear. The more/bigger bears you get the higher your score
(The game is FREE, you can pay $5 to get Infinite Honey, which lets you play as often as you want - by removing the cooldown for new levels.)
