MindWare's Marble Circuit is an addicting marble maze challenge! The single-player logic puzzle features colorful multi-directional tiles that form crisscrossing paths for 8 marbles. The challenge: place the tiles so the marbles land in the correct target spaces at the bottom of the board. 64 puzzle cards instruct how to position starting tiles and the goals for the target spaces. Use logic to place the remaining tiles, then slide the starting gate to release the marbles and see if you've correctly solved the puzzle.
