Clue 1

Integers

The station radar tracks altitude drops in the atmosphere. To read the secret coordinate, calculate the integer change in height.

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

(-1) + 9 =T

10 - (-1) =O

(-11) + 25 =S

(-3) + 24 =H

(-11) + 16 =X

(-4) + 13 =K

(-8) + 14 =D

9 - (-8) =L

(-14) + 36 =Y

21 - (-3) =V

16 - (-11) =N

(-2) + 6 =I

(-3) + 33 =A

(-9) + 24 =E

20 - (-9) =G

Clue 2

Percentages

The backup batteries are partially charged. Find the remaining percentage of redstone energy to unlock the locker room camera.

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

10% of 280 =T

25% of 184 =C

60% of 70 =N

50% of 70 =P

25% of 160 =S

10% of 100 =A

10% of 270 =D

0/13 letters found

Clue 3

Order of operations

To bypass the airlock security pad, we must solve a complex equation using the exact order of operations to prevent system lock.

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

Missing addends — the last clue

The cargo hold is missing several chests of building blocks. Find how many blocks are still needed to balance the ship's weight scale.

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

37 + ___ = 40

23 + ___ = 35

37 + ___ = 42

33 + ___ = 35

25 + ___ = 26

4 + ___ = 14

17 + ___ = 23

8 + ___ = 16

3 + ___ = 10

5 + ___ = 14

30 + ___ = 41

Step 2 — cross out the sentence with each answer

1.The villain teleported past the blast doors, then mined through the obsidian wall.

2.The villain stomped along the ceiling beams, then bashed open the emergency escape hatch.

3.The villain teleported past the blast doors, then stared directly into the supergiant star.

4.The villain melted the station core lock, then stared directly into the supergiant star.

5.The villain zoomed through the Zero G bay, then glided down to the reactor level.

6.The villain deflected the security drones, then survived the sudden depressurization.

7.The villain stomped along the ceiling beams, then survived the sudden depressurization.

8.The villain zoomed through the Zero G bay, then mined through the obsidian wall.

9.The villain melted the station core lock, then glided down to the reactor level.

10.The villain zoomed through the Zero G bay, then bashed open the emergency escape hatch.

11.The villain stomped along the ceiling beams, then mined through the obsidian wall.

12.The villain teleported past the blast doors, then bashed open the emergency escape hatch.

Answer Key — The Cosmic Redstone Sabotage

Culprit: Lizzie (Redstone Laser · Solar Visor · Right handed · Neon green hair · Slimeballs)

Clue 1 (Integers): "THE VILLAIN DOES NOT HAVE AN OXYGEN TANK"
(-1) + 9 = 8 (T) · 10 - (-1) = 11 (O) · (-11) + 25 = 14 (S) · (-3) + 24 = 21 (H) · (-11) + 16 = 5 (X) · (-4) + 13 = 9 (K) · (-8) + 14 = 6 (D) · 9 - (-8) = 17 (L) · (-14) + 36 = 22 (Y) · 21 - (-3) = 24 (V) · 16 - (-11) = 27 (N) · (-2) + 6 = 4 (I) · (-3) + 33 = 30 (A) · (-9) + 24 = 15 (E) · 20 - (-9) = 29 (G)

Clue 3 (Order of operations): "THE GRIEFER HATES SLIMEBALLS"
6 + 4 × 8 = 38 (T) · 6 × 5 - 6 = 24 (L) · 10 × 5 - 19 = 31 (B) · 11 × 7 - 17 = 60 (E) · 12 × 8 - 18 = 78 (R) · 7 + 7 × 2 = 21 (H) · 3 + 2 × 3 = 9 (G) · 7 × 12 - 7 = 77 (M) · 8 × 5 - 6 = 34 (I) · 89 + 4 × 5 = 109 (A) · 80 + 4 × 8 = 112 (F) · 12 × 11 - 21 = 111 (S)
Clue 4 (Exponents): "WE FOUND NEON GREEN HAIR IN THE AIRLOCK"
2^3 = 8 (W) · 11^2 = 121 (T) · 6^2 = 36 (O) · 2^5 = 32 (E) · 17^2 = 289 (I) · 2^7 = 128 (R) · 3^4 = 81 (C) · 13^2 = 169 (A) · 14^2 = 196 (G) · 5^2 = 25 (F) · 5^3 = 125 (H) · 12^2 = 144 (L) · 3^3 = 27 (U) · 4^4 = 256 (K) · 2^2 = 4 (N) · 4^2 = 16 (D)
Clue 5 (Missing addends): surviving statement (box 4) → Lizzie
37 + ___ = 40 = 3 · 23 + ___ = 35 = 12 · 37 + ___ = 42 = 5 · 33 + ___ = 35 = 2 · 25 + ___ = 26 = 1 · 4 + ___ = 14 = 10 · 17 + ___ = 23 = 6 · 8 + ___ = 16 = 8 · 3 + ___ = 10 = 7 · 5 + ___ = 14 = 9 · 30 + ___ = 41 = 11
