I've been playing Threes for just under a week and it's addicting! Plain and simple, it's rather genius if you ask me. The object of the game is to combine similar numbers e.g. 3+3 = 6 then follow that new number block of 6 with another to make 12 and so forth. The game ends when the board fills up and there are no more pairs left next to each other to combine. For a game that took over a year to build, it's worth supporting these developers at a cheap $1.99. Do it and I guarantee you'll love it! If you don't, then the challenge must have been too hard for ya. My highest block so far is 192. What's yours?
Update it's actually Number 1 on the App Store as of this morning! Congratulations to Sirvo and the gang!
