Block Out level guide
Block Out Level 20 Walkthrough
Block Out Level 20 is a two-room boss puzzle centered on a huge purple `5` block. Prepare the lower room, keep the green stem free, reduce the frame counters around the boss, and only then let the upper chamber resolve.
Board Notes
- Layout
- A huge purple rectangle marked `5` fills the upper chamber, connected to the lower room by a single green stem. The lower room holds red, blue, pink, and yellow blocks, with counters wrapped around the frame and a yellow bottom gate.
- Goal
- Service the upper boss block indirectly through the lower room until the top frame opens.
- Opening
- Clear space around the yellow bottom gate and keep the green stem unboxed while the upper counters fall from `7`, `5`, `6`, and `9`.
- Danger Zone
- Stacking the lower room to one side traps the stem and leaves the upper chamber impossible to service.
- Mechanics
- Level 20 is a boss-room board where two chambers share one narrow connector.
Quick Tips for Block Out Level 20 (spoiler-free)
- Protect the green stem.
- The lower room is support work for the upper boss.
- 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 20 — Full Solution
- Clear space around the yellow bottom gate in the lower room so the first counters begin to fall.
- Rotate the red and blue lower-room blocks without pinning the central green stem.
- Keep the purple `5` parked in the upper chamber while the top frame counters drop.
- Use the lower room to keep feeding the sides of the upper chamber until the boss frame is almost open.
- Free the green stem only after the lower room has enough empty space to absorb the next moves.
- Let the upper chamber finish once the purple `5` block is no longer locked by the frame.
- End with the last lower-room colors after the boss block has already cleared.
Colors in this level:
Purple, Green, Red, Blue, Pink, Yellow
Common Mistakes to Avoid
- Blocking the green connector with a lower-room color block.
- Trying to move the purple `5` while the frame counters are still high.
Frequently Asked Questions
What is the key piece in Block Out Level 20?
The green stem is the key connector. If it gets boxed in, the top boss block cannot be serviced.
Should the purple `5` move early in Level 20?
No. The lower room and the frame counters must be prepared first.
