Front-back, left-right, you'll probably need GPS to get through this logic game! Choose one of the cards each time and place the pawns on the board, which has the ability to tilt in various directions thanks to its special base. The goal of the game is to make the green balls fall into the hole located in the center of the game. The additional balls (blue ones that also move and green ones that remain still) will make the puzzle-solving process even more complicated. The package includes 40 cards for corresponding mental challenges.
