Block Out Level 123 Walkthrough

hard 7 colors

Block Out Level 123 wraps a perimeter frame around a central purple tube, with hammer-tool obstacles guarding the numbered pocket counters. The perimeter tiles must drain before the tube accepts input — and the green `3` tile highlighted with a yellow line is the gating piece. Clear the top-left pink pocket first, then work the hammer tools inward to open the tube.

Board Notes

Layout: Purple-framed board with large empty central purple grid holding orange `3`. Perimeter ring: pink `4` (top-left), green `5` (top-center), twin orange hammer-tool blocks (top-right), blue `4` (far right), blue `5` (left wall), white `1` (lower-left), blue `5` (left-bottom), pink row (bottom-left), green/orange (bottom-center), blue `2` (bottom-right). Mid-run: central green `3` highlighted with yellow vertical lane, wrench icons on hammer blocks.
Goal: The perimeter ring must clear before blocks enter the central purple tube. The twin orange hammer-tool blocks and the central `3` tile gate the first openings.
Opening: Peel the top-left pink `4` cluster and green `5` tile before touching the hammer-tool pair. Feed the left-wall blue `5` column without sealing the white `1` corner.
Danger Zone: Around 02:32 the central zone highlights green `3` with a yellow vertical line while orange wrench icons still sit on the top hammer blocks. Forcing the right-wall blue `2` pair into the tube before the hammer tools clear pins the green `3` block.
Mechanics: Perimeter-frame board with a central purple tube and hammer-tool obstacles. Numbered perimeter tiles (`1` through `5`) are pocket counters that must drain before the tube accepts interior blocks.

Quick Tips for Block Out Level 123 (spoiler-free)

Break the orange hammer-tool pair before feeding any blue tile into the central tube.
Keep the bottom pink row parked until the top perimeter is fully thin.
