Love it! Small remark: one of the 15x15 puzzles has no number(s) in its last column. Don't know if that's a bug or if it's meant to represent an empty column.
Love this concept. The graphics are really nice and polished too. There seems to be a bug though, if I scroll in-game my firefox window scrolls as well. Pretty irritating, I hope you fix it.
Anyone with the login failure, try going to the elements website and login on a new character. I went back to Kong while that website was open and was able to login again. :)
Some things aren't very easy to read. For example the difference between a "3" and a "5". Don't know if that's because your game is made for a bigger play field or maybe it's just the font you use.
Except for that, I like it. Not bad.
