Type - Puzzle Action

Released in Japan by Namco, this Atari original game brought to the Mega Drive by Tengen is probably best described as a square Puyo Puyo.  It's basically the same idea.  Instead of blobs falling down there are blocks coming down a conveyer belt.  You then need to sort these in to an order that will make them disappear just like Puyo Puyo.  You can line 3 of the same colour in either vertical, horizontal or diagonal lines to make them disappear.
