Jack (red=1) climbs a beanstalk (green=3) that grows upward through a vertical grid. At the top, a giant (grey=5, occupying multiple cells) guards golden eggs (yellow=7). In the masked grid, Jack has reached the top, grabbed a golden egg, and the giant has awakened — the giant's cells shift one position toward Jack, and Jack holds the egg (his cell becomes value 1 with a 7 adjacent).
