So I’m hooked on Threes, this brand new iOS game where you combine pairs of tiles to make bigger numbered tiles and then combine those with their pairs and keep going until the board fills up with tiles and you have no moves left.

It sounds simple — and it is — but the games developers spent an entire year trying variations on the artwork and gameplay before finally settling on this simplified version that takes just a minute to learn.

I’m feeling pretty happy right now because this morning I somehow managed to get a 384 tile, and thus catapulted into a new high score of 9,864. But that’s apparently small peanuts… check out Eric Pramono’s strategy for how he gets 768 tiles.
