2048:

How to play: Use your arrow keys to move the tiles. When two tiles add up to a 3-smooth number (a number with no prime factors larger than 3), they merge into one!

Hint: There are 4 ways that two 3-smooth numbers can add up to another 3-smooth number:

• n + n = 2n
• n + 2n = 3n
• n + 3n = 4n
• n + 8n = 9n

This is a mod of 2048 by Gabriele Cirulli, which is based on 1024 by Veewo Studio and conceptually similar to Threes by Asher Vollmer.
