Read on to learn how to solve this puzzle! But keep in mind that you need to draft this room first to access it.
Tips For Solving the Dartboard Puzzle

The first thing you may think when you enter the Billiards room is that you’ll be playing billiards, but no! In fact, you’ll be going straight to the dartboard in the back of the room.
In the Nook there is note that will tell you how to go about solving the dart board puzzle. Blue = Addition, Orange = Subtraction, Pink = Multiplication, and Purple – Division. You need to work from the inside out to solve it.
Solving The Dartboard Puzzle
Keep in mind that these examples aren’t the puzzles you will have. They are different with each passing day but it’s to show you how to go about solving the dartboard puzzle. Often, the blue will indicate the base number you start with.

Here we start with the number 16 so click 16.

This is one plus two, meaning you click on 3. Pretty easy!

Don’t panic. This has an answer! Working from the inside out, you start with 13 and then subtract 12 from it, giving you one.

This features multiplying. 4 is the base number so you times it by 2, giving you eight.

This is a two stepper. 9 is the base number. Subtract it from 7, giving you 2. Then you times the 2 by 10, giving you 20. Follow this basic premise and you’ll be ready to dust off those old math skills and put them to the test!
