OBSTACLE · lane transfer

Moving elevators: time block transfers between lanes

Elevators carry blocks between lanes on a cycle, so a clear route can close the moment a piece is lifted away.

MECHANIC RULES

How Ivy works

  • Moving elevators shift blocks from one lane to another on a repeating cycle.
  • A block loaded onto an elevator leaves its current lane and returns in a different lane after the cycle completes.
  • The App Store listing describes Block Out elevators as elements that carry pieces between lanes.

DECISION PRIORITY

Strategy checks

  • Watch the elevator cycle before committing a block that depends on staying in its lane.
  • Use the transfer to move a stuck color toward its exit instead of forcing a longer manual route.
  • Stage blocks near the elevator when the next cycle clearly helps the planned order.

AVOID

Common mistakes

  • Do not assume a block stays where you placed it once an elevator cycle starts.
  • Do not load a color you still need in its lane if the transfer would strand it.
  • Do not plan the whole route around one cycle without checking the return lane.
