Brain Blow Level 6

Overview

A faucet pours into a top cup, and pipes branch downward to three numbered cups below. The prompt asks which cup will fill up first. The routing of the pipes decides the answer, and after tracing the channels the solution is entered as a number on the counter beside the Ok button. Two arrow controls change the value on the counter, and there is no way to rearrange the cups themselves. The puzzle rewards careful line reading over a quick guess at the closest cup.

Step-by-Step Solution

1. Follow the pipe leaving the top cup and see how it splits toward the lower cups, checking whether any branch is blocked before it reaches its receiver. Closed segments are easy to miss because the drawing still shows a line where water cannot pass, so trace the full length of each route.

1. Trace each outlet to its numbered cup so you know which receiver the open channel actually feeds. Keep the cup numbers in mind as you follow the lines down from the branches, and note which route stays open the whole way.

1. Read the counter control below the board and set it to the number of the cup that receives the open flow first, using the plus and minus arrows until that number appears. The counter starts at an empty value, so the correct cup must be selected before confirming.

1. Press Ok to submit the number. The level completes when the entered cup matches the first one to fill; a wrong choice leaves the counter active for another attempt, and you should re-check the blocked branch rather than change the number at random.

Strategy & Reasoning

Pipes in these puzzles often look connected while one segment is closed off, so visual tracing matters more than counting branches. The cup nearest the faucet is not guaranteed to fill first; the water follows whichever open route reaches a receiver without a blockage, and a hidden closed segment can delay the closest-looking cup.

The answer is a single number, which means the puzzle expects one clear first cup rather than a shared fill order. Following each line from the top cup down to its outlet removes the guesswork, and the counter simply records that cup's number rather than requiring any rearrangement of the cups. The taps to change the counter are secondary once the correct cup is identified.

Tips & Common Mistakes

• Do not assume the cup closest to the top fills first; check whether its pipe is actually open all the way down before committing to that number.
• Follow one pipe at a time instead of scanning the whole diagram, so you do not mix branches together and misread which outlet belongs to which cup.
• If the number is rejected, re-trace the hidden blockage before changing the counter; a blocked branch delays that cup even when it looks nearest, and repeating the same guess will not help.
