AdBac Peg is a puzzle game that trains attention and commonsense.
The purpose of this puzzle game is to rearrange the positions of the green and blue gems in the fewest number of moves.
Click on a gem to move it into a vacant square. A gem can either be moved to a neighboring vacant square, or jumped over a neighboring piece (of either color) to the vacant square. Touch with your finger to choose which gem to move, and if its a permissible move, the gem will pop over to the empty square, thus leaving the moved gems square vacant.
