Butterfly Kyodai is a tile-matching game where you can free the butterflies by making pairs of wings that are the same. By matching two of the same butterfly, you can make them fly away gracefully. Most of the rules for mahjong are used in Butterfly Kyodai. Tap on a butterfly wing, and then find a tile that matches it. You can only match tiles that can be connected by a line. This line can't go through any other tiles, and it can't turn more than twice at 90 degrees. The line can't go through other butterfly wings either; it must always go around them. The only exception is when two identical tiles are right next to each other. In this case, you don't need to draw a line to connect them.
