There are 100 levels. I solved the first 10 pretty quickly, then jumped to the last 10. I found those just as easy.
This is a good game for novice puzzlers. The graphics are nice.
What's lacking is a 'moves counter' for purists who want to do each level using the minimum number of moves
Related: I regularly check 'Apps Gone Free'. They had this game listed as being free about a week ago,, but now it's not. If you find a good puzzle that's temporarily free, send me note or leave a comment & I'll spread the word.
