Vintage Wednesdays: SAME

From Wikipedia.org

SameGame (さめがめ?) is a tile-matching puzzle originally released under the name Chain Shot! in 1985 by Kuniaki Moribe (Morisuke). It has since been ported to numerous computer platforms, handheld devices, and even TiVo.[1]

This is a simple implementation of the Same game done in one day. It would be the first of the (hopefully many) games product of the Vintage Wednesdays Challenge: make a simple vintage game in one day each week.
