Clue 1

Subtraction

We found a pile of corrupted data packets in the main server room. After subtracting the deleted backup files from the total spam logs, the remaining count reveals a hint about the rogue hacker's gear.

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 5

Fractions of a number — the last clue

A portion of the deleted server log has been recovered. Finding the fraction of these restored files gives us a direct coordinate to track down the suspect's exact hair type.

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
2/6 of 15 = ?
1/5 of 5 = ?
1/6 of 42 = ?
6/10 of 5 = ?
1/10 of 80 = ?
1/4 of 8 = ?
3/8 of 32 = ?
2/3 of 9 = ?
1/6 of 24 = ?
5/10 of 22 = ?
1/5 of 50 = ?
Step 2 — cross out the sentence with each answer
1.The villain spawned a giant brick rain storm, then healed up using a regeneration coil.
2.The villain ran the infinite jump script, then fired a shot from a hyperlaser gun.
3.The villain activated an illegal avatar morph, then fired a shot from a hyperlaser gun.
4.The villain ran the infinite jump script, then swung a glowing ban hammer.
5.The villain triggered a massive gravity shift, then slashed the air with an illumina sword.
6.The villain activated an illegal avatar morph, then sprang away with a speed coil.
7.The villain ran the infinite jump script, then healed up using a regeneration coil.
8.The villain spawned a giant brick rain storm, then sprang away with a speed coil.
9.The villain spawned a giant brick rain storm, then fired a shot from a hyperlaser gun.
10.The villain caused a complete server crash, then sprang away with a speed coil.
11.The villain ran the infinite jump script, then sprang away with a speed coil.
12.The villain triggered a massive gravity shift, then fired a shot from a hyperlaser gun.
