Move the other blocks to get the dark blue one out. I've been playing this way too much lately.

Some are easier then you would think, 17 moves for level 13 for example. Level 14 is quite a bit more difficult.

level 13is a biatch

ok i got level 13 in 14 moves and level 14 in 22.
now 15 is a biach

Wait until you get to some of the higher levels. I had to walk away a couple of times and start fresh because I couldn't figure them out. It's just so darn addictive.

No kidding. 25 has gotten me. I've been on it for 20 mins at least. I'm giving up now that my brain is refusing to work any more. Time for a cigar on the back porch.
