How to Solve Block Out Level 638 — Full Solution
- Send the small yellow starter through the bottom yellow gate, clear cyan/light-blue through left/top routes, and take the green square through the bottom green gate.
- With right 4 at 1, send the cyan vertical through the top cyan gate; the cover reaches 0 and reveals the upper-right stack.
- Pull the newly revealed green 2-by-2 downward first, then peel cyan, yellow, green, and red from exposed edges.
- Turn the purple framed corner through lower center and remove long pink/blue pieces without occupying the row beneath left 16.
- Alternate complete right, bottom, and left exits so left 16 counts down while its cross-lane remains usable.
- With left 16 at 1, send the light-blue outlined L through the right blue gate; the cover reaches 0 and reveals the bordered top-left grid.
- Send the newly revealed yellow 2-by-3 through the bottom yellow gate first, then clear cyan/red and the bomb-marked green column.
- Route the outlined purple/cyan corner, blue rectangle, pink bars, and red pieces through their edge gates.
- Clear the penultimate blue and purple pieces, leaving the isolated lower-right pink vertical.
- Move the pink vertical upward through the top pink gate as the final object; the verified board is empty.
Colors in this level:

Common Mistakes to Avoid

Quick Tips for Block Out Level 638 (quick clues)

Board notes 5 details
- Layout
- Large covers marked left 16 and right 4 dominate the board above a starter of purple, green, cyan/light-blue, blue, yellow, and pink pieces.
- Goal
- Open right 4, protect the cross-lane while clearing its full-height stack, then open left 16 and drain the bordered-grid finale.
- Opening
- Use the bottom yellow/green and cyan routes, then send the cyan vertical through the top cyan gate with right 4 at 1.
- Danger Zone
- The row beneath left 16 and the slim right wall are shared by the early hook, late outlined L, and terminal pink columns.
- Mechanics
- Right 4 finishes with cyan vertical to top cyan; left 16 finishes with light-blue outlined L to right blue; the last pink vertical uses the top pink gate.
