You must complete the magical ring with pieces that are coincident by their symbol or color. It's the only way to protect yourself against the dragon! The game offers various pairs of symbols with their respective colors, and you must complete the ring so that the last piece is coincident on both sides. In certain cases you'll be asked to rely exclusively on a match by color or by symbol to put together the pieces. When you don't have a good piece to continue, you can click at the 'DEAL' button to obtain new ones. But you cannot repeat this more than 3 times, after what you'll have to continue with the pieces you have at this moment. The game will give you points not only for making a good ring, but also for making a ring as full of variety in color and symbols as possible (a ring with more variety is a more precious ring). Enjoy!
Click at the piece that you want, then drag and drop to its final position at the ring.
