Well when you have to crack the code. It means you have 3 guesses until the timer starts, grey means wrong number, yellow means right number wrong spot and green means right number right spot ( you have to guess the code) . now for the satellites, you have to put the five chips over each slot until the branches connect. Then you have to stop the satellites for the dot on the coloured rings to hit the right coloured satellite ( as soon it's near let go).
