A door will only open if a code is entered into it. Select colours and numbers for 5 arrows in a loop to make a Coloured Loop. The door will only open if all the arrows follow these rules: 1. Any arrow you land on must be the same color as the arrow you jumped from. 2. All the arrows that are the same color need to form a single loop — no matter which of the arrows you start at, you must eventually land on every arrow of that color and return to the arrow where you started without ever landing on an arrow that's a different color. Enter the codes into the arrows to make Coloured Loops!
