To play. You have to guess the right color code. The color code is always 4 colors, when you click the button that says “Check” on the top. It shows a slot1,2,3, and 4. Green = correct spot, Yellow = correct but misplaced, red = not in color code. And the colors of green, yellow, and red they mean is for the order you put them in. So like if you put a blue in slot 1, and the result was 4153. Then it would be yellow. So the colors of the slot1,2,3, and 4 colors are for the order you put them in. Your goal is to get the correct color code. To know that you got it right, the colors in the slots1,2,3 and 4 will all have to be a color green. Then, it changes the result for a new round. Then you have to guess the second color code. It goes on and on. Hope you Enjoy!
