Clue 1
Rounding
Our blocky radar scans the horizon. It can only show rounded numbers of blocks. Let's round the coordinate readouts to get the first 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 5
Division facts (1-12) — the last clue
The robotic guards want to split the remaining energy cubes equally among their squads. Divide the loot to solve the final clue.
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
15 ÷ 3 = ?
60 ÷ 6 = ?
3 ÷ 3 = ?
27 ÷ 9 = ?
22 ÷ 11 = ?
72 ÷ 9 = ?
77 ÷ 11 = ?
108 ÷ 9 = ?
30 ÷ 5 = ?
9 ÷ 1 = ?
77 ÷ 7 = ?
Step 2 — cross out the sentence with each answer
1.The villain marches safely across deep lava lakes, then drills a massive escape tunnel.
2.The villain fires a barrage of lit TNT blocks, then drills a massive escape tunnel.
3.The villain spawns infinite diamond blocks, then boosts the signal with a repeater.
