Block Out level guide
Block Out Level 171 Walkthrough
Block Out Level 171 stacks a domed upper color band above an orange-framed lower chamber, then reveals a second layered stack once the dome clears. Open the dome from its outside edges, keep the center column empty as the only connection, and peel the lower bands from top to bottom without parking a long piece across the middle.

How to Solve Block Out Level 171 — Full Solution
- Clear the exposed purple roof pieces and cyan upper-edge pieces through their matching gates.
- Remove the left red horizontal band while the left lane is still open.
- Send the right green and yellow pieces outward, creating a clear vertical channel through the dome.
- Finish the remaining blue and cyan blocks in the upper chamber before engaging the lower stage.
- Peel the revealed lower stack one horizontal band at a time, beginning with cyan and green.
- Remove the red and yellow middle bands without parking either across the center.
- Clear the final purple and orange marked pieces beneath the stack for the completion state.
Colors in this level:
Purple, Cyan, Green, Red, Yellow, Blue, Orange
Common Mistakes to Avoid
- Parking a long lower band across the center and splitting both side exits.
- Treating the first lower chamber clear as the finish and ignoring the second stack that appears on top of it.
Quick Tips for Block Out Level 171 (quick clues)
- Keep the dome center column empty—after the first chamber clears it becomes the only feeder into the second stack.
- Peel lower bands as whole horizontal rows; diving a long piece into the middle splits both side exits.
Board notes 5 details
- Layout
- Domed upper board packed in horizontal color bands—purple on the roof, cyan and green in the upper-middle, red and yellow across the lower band—above a separate orange-framed lower chamber with narrow marked columns on its flanks.
- Goal
- Clear the domed stack without sealing its side exits, drain the newly exposed lower horizontal bands, and finish the final purple and orange marked pieces under the stack.
- Opening
- Take the exposed upper purple and cyan edge pieces first, clear the left red band and the right green and yellow traffic, and open a vertical channel through the dome before engaging the lower stage.
- Danger Zone
- When only the lower horizontal bands remain, sending a long piece into the center too early divides the board and stops the opposite color from reaching its side gate. The apparent lower chamber is also not the finish—a second stack appears across its top.
- Mechanics
- A domed band puzzle that continues into a second layered stack after the dome clears; the center column is the only connection between stages.
Frequently Asked Questions
Why is the first lower-chamber clear not the finish?
A second layered stack appears on top of the cleared chamber. Stopping early leaves the dome still packed with no planned route into stage two.
What does parking a long lower band in the center break?
It divides the board so the opposite color cannot reach its side gate, and it also seals the column the second stack needs later.
