Board notes 5 details
- Layout
- Four trucks sit above a squared U, four vertical trucks fill its center, and a three-truck lower reserve begins partly hidden by a red curtain.
- Goal
- Clear all three tiers through the same right bend and bottom return until four HUD groups and every truck position are complete.
- Opening
- Route upper yellow and orange first, then separate central green and light blue before using upper pink or brown.
- Danger Zone
- Pink released into light-blue traffic at the right bend delays the next brown/gray receiver; covered and curtained faces remain unknown.
- Mechanics
- Three source tiers, a single U-shaped route, one lower red curtain, a covered upper stack, and late purple/black reveals stage four completion groups.
