Using the Battle Cubes is easy. First, select a secret attack. This gives you an edge in the game. Then, set your cube to battle mode. When you're ready, slide your cube against your opponent's cube. The one who wins gets a token and captures the loser's cube. Remember, each pack comes with tokens. You can trade these tokens with your friends or try to win more by playing. These tokens are also puzzle pieces, so keep collecting to complete the puzzle. There are 12 rare tokens, so keep an eye out for them! As for maintenance, keep your cubes in a dry place. Avoid dropping them too hard as it might damage the cube. Have fun playing and collecting all the amazing Battle Cubes!
