Clue 1

Fractions of a number

To unlock the server logs, we must analyze the fractional bytes of the highest score.

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

The backup security database will boot once we solve for a fraction of the encryption keys.

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 6 = ?
4/10 of 15 = ?
4/5 of 10 = ?
1/6 of 6 = ?
2/8 of 48 = ?
1/4 of 28 = ?
2/6 of 15 = ?
1/4 of 16 = ?
4/10 of 25 = ?
1/10 of 30 = ?
1/2 of 22 = ?
Step 2 — cross out the sentence with each answer
1.The villain activates a massive lag spike, then survives the firewall defense with infinite lives.
2.The villain initiates a sudden data warp, then speeds past security with a turbo boost.
3.The villain triggers a bright pixel burst, then deflects the laser grids with an invincibility shield.
4.The villain activates a massive lag spike, then evades the drone guards with a gravity flip.
5.The villain forces a confusing frame skip, then evades the drone guards with a gravity flip.
6.The villain initiates a sudden data warp, then deflects the laser grids with an invincibility shield.
7.The villain initiates a sudden data warp, then evades the drone guards with a gravity flip.
8.The villain activates a massive lag spike, then escapes with a quick double jump.
9.The villain causes a wild screen shake, then escapes with a quick double jump.
10.The villain activates a massive lag spike, then speeds past security with a turbo boost.
11.The villain forces a confusing frame skip, then deflects the laser grids with an invincibility shield.
12.The villain causes a wild screen shake, then evades the drone guards with a gravity flip.
