A puzzle for those who know the new online game 2048 — doubtless very easy for many of you, but might be fun for your kids, if they play:

Say that I make up a new game — let’s call it 11. The tiles are numbered 1 to 11, and when two tiles with the same number are combined, they yield a tile with a number that’s one higher (so, for instance, two 6s become a 7). You start with 1s, and the goal is to get an 11. Otherwise, tiles combine and new tiles arrive as in 2048.

How is game play in 11 similar to, or different from, game play in 2048?
