How to Solve Brain Out Level 37 — Full Solution

  1. Trace the path from the faucet through the top tank before you think about any cup number.
  2. Cross out the blocked upper-left route instead of assuming cup 1 is playable.
  3. Eliminate the far-right lower branch as well because that side does not stay open to the end.
  4. Choose cup 4 after the dead branches are gone.

Quick Tips for Brain Out Level 37 (quick clues)

  • In Brain Out pipe puzzles, edge cups are often bait. Trust the branch logic, not the position on the page.
Board notes 5 details
Layout
Level 37 is a branching faucet diagram with numbered cups under a small tank. The left side feeds cups 1, 3, and 4, while the right side feeds 2, 5, 6, and 7.
Goal
The board is not asking which cup sits lowest. It is asking which route is still truly open after the blocked branches are ruled out.
Opening
The video starts crossing out the tempting dead routes instead of choosing a cup immediately. The upper-left branch is rejected early, and the far-right lower branch is also eliminated before the final answer is chosen.
Danger Zone
If you follow the drawing without checking closures, cups on the outer edges look viable when they are actually dead.
Mechanics
This is a branch-elimination puzzle. The winning cup is found by crossing out blocked routes, not by comparing heights.
