Key Rules
Objective: Extract all artifacts before your fuel
runs out. Every artifact crushed is a mission failure โ you
can't win with a lost artifact.
Gravity: After any clear, blocks fall down to fill empty
space. Empty columns remain as permanent shafts โ the rock
doesn't slide sideways. Plan carefully: clearing an entire column
splits the board in two.
Crush Rule: A block that falls 2+ tiles and lands
directly above an exposed artifact destroys it instantly โ
immediate mission failure. Clear gently around exposed
artifacts.
Fuel: Cluster clear = 1 ยท Sandstone hit = 1 ยท Dynamite = 2.
Hit zero before extracting all artifacts = mission failed.
