The dartboard challenge in the Billiard Room seems straightforward at first—but after a few rounds, you might feel like you've been ambushed by a pop quiz from your ninth-grade algebra teacher, complete with flashy neon hues and a side of mental fatigue. The silver lining? Once you crack the code of how it functions, even the most tangled puzzles become solvable. And if all else fails, there's always the Upgrade Disk to bail you out.

Understanding the Dart Puzzle Mechanics

Every puzzle is randomly generated, but the core logic remains consistent. Forget actual darts or standard game rules—this is all about color-coded math operations. You process each number from the bullseye outward, step by step, ignoring traditional order of operations.

Here’s your color cheat sheet:

• Blue = Add
• Yellow = Subtract
• Pink = Multiply
• Purple = Divide

Special Symbols and Their Effects

As you progress, the game cranks up the difficulty with new symbols appearing on the board:

• Square icon in the center = Square the current value
• Diamond icon = Reverse the digits (e.g., 91 becomes 19)
• Wavy lines = Round to the nearest 10 or 100
• Red dot on a segment = Perform that operation again (one extra time per dot)
• Red slash = Halve the result
• Red X = Ignore that number completely

Spoiler: It gets wild.

Walkthrough Examples

Simple Round

• Begin with 13 (blue)
• Subtract 12 (yellow) → 13 - 12 = 1
• Multiply by 1 (pink) → 1 × 1 = 1

Multi-Step Scenario

• Start with 18
• Subtract 8 → 10
• Multiply by 4 → 40
• Divide by 20 → 2

Using the Square Rule

• Start with 20
• Subtract 1 → 19
• Subtract 13 → 6
• Multiply by 1 → 6
• Square the result → 62 = 36
• Divide by 12 → 3

Applying the Flip Mechanic

• 10 × 10 = 100
• Subtract 9 → 91
• Flip digits → 19

Simplifying the Challenge

Eventually, the puzzles evolve into something that feels less like a game and more like a psychological test. Luckily, relief is available.

Locate a computer terminal in the mansion and insert an Upgrade Disk to activate the Speakeasy mode. This transforms every dartboard puzzle into basic addition only. Say goodbye to squaring, flipping, and rounding—this is math at its most peaceful.

Other useful upgrades include:

• Break Room – Automatically receive a Keycard the next day
• Pool Hall – Unlocks additional rooms like the Great Hall and Foyer during daily drafts (mostly cosmetic)

Final Thoughts

You don’t need a PhD in mathematics to conquer the dartboard puzzle. Just stick to the color rules, move from center to edge, and stay calm when the board throws you a curveball like digit-flipping or exponentiation. Or, take the easy route: enable Speakeasy and live in blissful arithmetic simplicity. The power is in your hands.
