This is a challenging puzzle game! Your task is to recharge the electric toys on the assembly line. The core gameplay of the game is to power the toys according to their colors by clicking on the battery boxes of the corresponding colors below. The number of batteries loaded in the large and small boxes is different, and the required number will be clearly displayed above the toys. You need to accurately match the color and quantity. More importantly, there are only 6 empty spaces for storing boxes. Once they are full but there are no matching toys, the game will fail. As the levels advance, the color combinations of toys become more complex and the power requirements vary more. You need to reasonably allocate boxes of different sizes to balance color matching and space utilization. Experience the ultimate fun of strategic puzzle solving!
