Block Out level guide
Block Out Level 21 Walkthrough
Block Out Level 21 is a triple-boss ladder. Break the framed `9` panel first, unwind the colorful middle strip second, and only then start shrinking the lower `16` and `18` panels.
Board Notes
- Layout
- Three framed purple bosses marked `9`, `16`, and `18` stack down the board. A colorful middle strip of blue, yellow, green, red, and pink bars separates them, with top counters `1` and `5`, a left counter `12`, and a green floor exit.
- Goal
- Open the top boss first so the middle and lower bosses can finally interact.
- Opening
- Clear the upper counters and expose the framed `9` panel before working on the larger values below.
- Danger Zone
- Starting on the lower bosses too early keeps the middle strip crowded and the top frame locked.
- Mechanics
- Level 21 is a top-down boss ladder where each framed panel depends on the one above it.
Quick Tips for Block Out Level 21 (spoiler-free)
- Solve the framed `9` first.
- The lower `16` and `18` values are phase two and phase three.
- Think in chain clears. The best move is the one that sets up the next two moves, not just the quickest current match.
How to Solve Block Out Level 21 — Full Solution
- Work the top counters and clear the upper color band so the framed `9` panel is exposed.
- Drop the `9` panel before touching the lower bosses.
- Use the freed middle corridor to rotate the pink, green, and blue bars.
- Start shrinking the lower `16` panel once the center is no longer packed.
- Let the `18` panel begin falling only after the `16` frame has already opened.
- Save the floor green exit for the late cleanup when the lower panels are thin.
- Finish with the remaining tall color bars after both bottom bosses have collapsed.
Colors in this level:
Blue, Yellow, Green, Red, Pink, Purple
Common Mistakes to Avoid
- Trying to shrink the lower framed values while the top `9` is still alive.
- Leaving the middle strip packed after the top boss has opened.
