Ivy obstacle: reveal covered doors
Ivy covers exit doors until block clears trim it away, so routing decisions must account for exits that are not available at the start.

MECHANIC RULES
How Ivy works
- Ivy covers doors and prevents those exits from being treated as open routes.
- Clearing blocks trims the Ivy and reveals the covered doors.
- Grand Games introduced Ivy in the iOS Version 729 release notes dated July 20, 2026.
DECISION PRIORITY
Strategy checks
- Identify which colors depend on covered doors before committing blocks to narrow holding lanes.
- Prefer early clears that both remove a block and advance access to a needed Ivy-covered door.
- Re-evaluate the route as each door appears; the safest lane can change after the cover is removed.
AVOID
Common mistakes
- Do not park a required color in front of a lane whose matching door is still covered.
- Do not assume every visible edge is usable before the Ivy-clear condition has been met.
- Do not copy an Ivy route to a board whose covered-door positions differ.
