Clue 1

Subtraction

We scanned the damaged database. We had a total pool of backup files but the hacker deleted a portion of them. Subtract the missing files to find the recovery code.

Solve each problem to learn its letter. Then write that letter in every box that shows the same number, and read the secret clue.

Clue 2

Addition

The hacker left corrupted script blocks across multiple game servers. Our security team tallied the corrupted blocks and added them together to crack open the next secret file.

Clue 3

Multiplication facts (1-12)

We found a suspicious grid of repeating firewall packets. By multiplying the rows of packets by the columns we can bypass the encryption and unlock a clue.

Solve each problem to learn its letter. Then write that letter in every box that shows the same number, and read the secret clue.

Clue 4

Fractions of a number

Our security scanner needs a specific fraction of the remaining database processing bandwidth to run a deep scan of the player systems.

Solve each problem to learn its letter. Then write that letter in every box that shows the same number, and read the secret clue.

3/5 of 45 =W

1/4 of 72 =F

1/2 of 28 =E

2/4 of 18 =B

5/10 of 56 =H

1/6 of 48 =R

1/6 of 72 =S

3/6 of 34 =T

3/6 of 22 =O

1/2 of 70 =N

2/6 of 30 =D

2/5 of 65 =A

4/6 of 3 =U

3/10 of 50 =C

0/15 letters found

Clue 5

Fractions of a number — the last clue

To locate the hacker physical computer setup we must analyze a fraction of the incoming server mouse click coordinates.

First solve each problem. Then find each answer in the list below and cross that sentence out. One sentence will be left — that's exactly what the villain did!

Step 1 — solve these

1/2 of 8 = ?

1/10 of 10 = ?

2/4 of 16 = ?

3/6 of 24 = ?

1/8 of 16 = ?

1/2 of 12 = ?

2/8 of 44 = ?

2/10 of 25 = ?

4/8 of 6 = ?

1/10 of 70 = ?

1/3 of 27 = ?

Step 2 — cross out the sentence with each answer

1.The villain spawns giant neon blocks, then disables the chat box.

2.The villain injects a custom script, then disables the chat box.

3.The villain deletes the spawn location, then disables the chat box.

4.The villain freezes all online players, then locks the game files.

5.The villain teleports past the lobby barrier, then locks the game files.

6.The villain deletes the spawn location, then steals the golden crown.

7.The villain teleports past the lobby barrier, then corrupts the main server.

8.The villain injects a custom script, then steals the golden crown.

9.The villain injects a custom script, then corrupts the main server.

10.The villain spawns giant neon blocks, then steals the golden crown.

11.The villain freezes all online players, then disables the chat box.

12.The villain spawns giant neon blocks, then locks the game files.
