Here are some playing tips to help you win the mosaics:
• Try to remove all the secondary and tertiary colors from the corners of the board first.
• Next, remove all the secondary and tertiary colors from the edges of the board.
• As the game progresses, keep trying to consolidate all the tiles in one area; don't leave tiles spread out all over the board, or you'll find that you won't be able to go back for them
• Use Undo liberally! Its very common to get stuck near the end of a game, and still win by Undo-ing a few moves and trying a different approach.
• To win in as few moves as possible, make complex moves; for example, jump a secondary over another secondary to remove several tiles in one move, resulting in a better score at the end of the mosaic.
