1) Click 'See inside'. 2) Copy the code onto the other sprites. The two variables (Time and Score) have already been set up. 3) Change the time (the other sprites should appear after a random number of seconds, already copied onto them). 4) You should award the players with 1 point if clicking on the red presents and take 2 points (-2) if clicking on the blue ones (also this on the sprites already).
