How to solve the Dartboard Billiard Room puzzle in Blue Prince
The Dartboard puzzle in Blue Prince has a few basic mechanics you have to keep in mind. For starters, each of those colors on the board indicates a mathematical operation. The circular board is divided into 20 parts, each representing a number. There are multiple inner circles, too, divided into several parts to help you build an equation to solve.
Here’s what the color codes indicate:
- Blue: Addition
- Yellow: Subtraction
- Pink: Multiplication
- Purple: Division
Instead of the iconic BODMAS rule, the Dartboard puzzle follows a system of its own: It uses the partitions on the board to decide which operation to solve first. To elaborate further, you begin from the center and solve your way out to the edge of the circle.
Here’s a basic Dartboard puzzle that spawned during one of my sessions to help you understand:

- We start with the number in blue, which is 10 in the first inner circle from the center. Since it’s the first number we have in the equation, we add it to zero: 0+10=10.
- In the second inner circle, we have two numbers—four and two—depicted in yellow (subtraction). So, we subtract those two numbers from the result that we got in step one: 10-4-2=4.
- In the third inner circle, we have one pink (multiplication) operation with two. So, we multiply two with the result we got in step two: 2×4=8.
- In the fourth inner circle, we have one purple (division) operation with two. So, we divide the result we got in step three with two: 8/2=4.
- The answer is four.
As you progress in days or draft Billiard Rooms at higher ranks, these puzzles will get substantially difficult. In fact, you may soon encounter a colored square or other symbols at the center or edge of your Dartboard, leaving you wondering what they depict.
Here’s a table to explain what these Dart Puzzle symbols mean in Blue Prince and how to tackle them.
Symbol | Location | Meaning |
---|---|---|
Square | Center of the board | Complete the operation depicted by the square’s color first. Then, square the result. So, four becomes four times four, which is 16. |
Diamond | Center of the board | Complete the operation depicted by the diamond’s color first and then invert the number. So, 31 becomes 13. |
Red X | Edge of the board | Ignore all operations in this division. |
Two red circles | Edge of the board | Calculate every operation in this division twice. |
Red / | Edge of the board | Divide the result of this division by two. |
Two curved lines | Center of the board | When you get a fraction, round the number to the nearest one. |
Four curved lines | Center of the board | When you get a fraction, round the number to the nearest 10. |
Six curved lines | Center of the board | When you get a fraction, round the number to the nearest 100. |
