You remove tiles from the board by matching tiles that are alike (similar to Mahjong). However, you can only match them if a line can be drawn between them with a maximum of 3 segments (2 corners). Tiles right beside each other can be connected with a straight line. Wall tiles cannot be removed and create obstacles. Tiles with a "?" show the actual tile for a limited time when touched. We have designed 50 levels so you can start off easy and work your up to the challenging ones! Enjoy.
