Pegs N Holes- free puzzle app for ipad, iphone and windows phones.

 

Jordan Naftolin is the author of Pegs 'N Holes. The objective is to transfer the pegs into the holes, obviously.  The grid sizes range from 4x4 to 9x9.
I've solved a few levels at each grid size.  They go pretty fast.  On the 9x9 boards, my fastest time is 162 seconds.
Pegs 'N Holes has great graphics. It's not terribly hard, but it is fun. I highly recommend this for young puzzlers.
