I’m sure you still remember Threes, a fun (and addictive) number puzzle game for the iPhone. The app was a great success on the App Store, even reaching the top spot for paid iPhone apps.
Soon afterwards, many people created their own versions of the game -- one of the most popular being 2048. It started as a free browser game, but quickly transformed into a free iPhone app with ads. It’s been the #1 free iPhone app for a few days now.
How to Play
2048 has a gameplay similar to Threes. It uses numbered tiles, and will combine two tiles with the same number into a tile of their sum. You play the game until you unlock the 2,048 tile or until the 4x4 board is filled with tiles. The recent update to this app allows you to continue playing after you reach the 2,048 tile.
