- Purple: Indicates division
- Yellow: Denotes subtraction

The mathematical operations’ order is determined by how close each color is to the bullseye. As players complete additional runs, the puzzle’s complexity increases. It is also important to be aware of several advanced symbols that can alter your calculations:
- Square: Square the number (multiply it by itself)
- X: Skip this step
- Two lines: Round to the nearest whole number
- Four lines: Round to the nearest ten
- Diamond: Reverse the digits in the number
- Six lines: Round to the nearest hundred

- Red dots: Repeat the previous action according to the number of dots present
Deciphering the Billiard Room Dartboard Puzzle
To illustrate how to work through the billiard room dartboard puzzle, here is a step-by-step example:
Step 1

If a section lights up in blue, it signifies the addition operation. Simply click on 7 as there are no other numbers or colors displayed.
Step 2

Next, you’ll need to combine two blue segments. Thus, the calculation becomes 5 + 6 = 11. Choose 11 as your answer.
Step 3

Yellow represents subtraction. Begin with 15 and subtract 7, resulting in 8. Select this as your solution.
Step 4

In this scenario, 19 is positioned nearer to the bullseye, while 15 is in the outer area. By subtracting 4 from 19, you arrive at 15 as the answer, which should be selected.
Step 5

For this calculation, multiply 2 by 6 to get 12, adhering to the pink color’s definition of multiplication.
Step 6

As you advance, expect increasingly complex challenges. For instance, starting with 17, subtracting 15 yields 2. You then multiply that result by 2 to arrive at 4.
Rewards for Completing the Puzzle

Upon successfully completing the billiard room dartboard puzzle, players can expect varied rewards. These can range from an electronic keycard to other essential items like the Secret Garden Key. These rewards are designed to further your progress in the game, making the effort to solve the puzzle well worth it.
