Make sure to not let your mind give these cards in your memory a reboot, or else this Astro Boy new game will be harder, on finding out their position. The goal is to achieve an empty board, matching two tiles at a time, which happens each time two that are exactly the same regarding looks are selected and matched. Up to two at the same time, seek not for the hero and the other characters in varied positions. The cards must be really the same, not being allowed different expressions. Good luck!
