2048 vs Threes: Key Differences

Threes launched on iOS in February 2014, about one month before 2048. Both games involve sliding and merging numbered tiles, but they differ in meaningful ways:

Number systems

Threes uses a 3-based system: 1 + 2 = 3, then pairs of equal tiles merge (3 + 3 = 6, 6 + 6 = 12, etc.). The special rule is that 1 and 2 must combine first, then only equal tiles merge. 2048 uses pure powers of 2: any two equal tiles anywhere on the board merge when they collide. 2048's rules are simpler to grasp immediately.

Cost and accessibility

Threes was a paid app ($1.99 at launch) designed and developed over 14 months. 2048 was free, open-source, and built in a weekend. This single difference accounts for much of the difference in reach - A free browser game with no download required will always have a larger audience than a paid mobile app.

Tile behavior

In Threes, tiles only merge if they are adjacent and one is exactly half the value of the other. In 2048, any two equal tiles merge when they collide, regardless of their relationship to adjacent tiles. This creates a faster, more forgiving merge loop in 2048.

Who came first?

Threes came first by about one month. Gabriele Cirulli, who created 2048, publicly acknowledged that 2048 was conceptually similar to Threes. The makers of Threes publicly noted the similarity, calling 2048 and other clones "the unfortunate (and flattering) side effect of the market." Both games have their own depth, but 2048's accessibility made it the dominant variant.
