Brain Blow Level 64

Overview

A tap pours water into a central container that branches into a network of yellow cups numbered 1 through 7, connected by thin pipes. The prompt asks which cup will fill up first, and a counter at the bottom with minus and plus buttons plus an Ok button lets you enter a number. At first glance several branches look connected, but a few pipe joints are sealed, and the cup marked 2 covers part of the routing. The real open route leads down to cup 5, which is the first cup that would fill.

• Difficulty: Regular
• Estimated moves: 3

Step-by-Step Solution

1. Read the prompt asking which cup fills up first, and follow the pipes downward from the tap. Water enters the central container under the faucet, then splits toward the left cluster around cups 1, 3, 4, and 7 and the right cluster around cups 2, 5, and 6.

1. Check the openings where each pipe joins a cup. Many of the apparent branches are sealed at the joint, so water cannot enter those cups even though the pipe outline reaches their side. Trace each branch only where the connection is actually open.

1. Focus on the right side where the cup labeled 2 sits. This container covers part of the pipe behind it, hiding the outlet that continues downward.

1. Drag the number 2 cup aside to move it out of the way. With it shifted, the open pipe underneath becomes visible and shows the water continuing down toward cup 5 rather than toward the neighboring cup 6.

1. Confirm the route: from the central container, the open line goes through the right-side branch and straight into cup 5. The other visible branches lead into sealed joints or capped pipes, so they will not fill before cup 5.

1. Use the plus button to raise the counter to 5, then tap the green Ok button. The level accepts 5 as the first-filling cup and the completion screen appears.

Strategy & Reasoning

Pipe-network puzzles are decided by open joints, not by how close a cup looks to the tap. A pipe that touches a cup's side but ends at a sealed wall cannot carry water in, which is why several numbered cups appear connected but never fill. Working branch by branch and checking each opening avoids picking the nearest-looking cup by distance alone.

The cup 2 label is placed over the routing on purpose, so moving it aside is the hidden step that reveals where the right-hand pipe actually exits. Once that cup is shifted, the branch to cup 5 reads as the only open downward line on the right, while the pipe toward cup 6 stops at a sealed connection. Entering 5 and confirming completes the level; there is no need to guess the other cups once the open path is traced to its end.

Tips & Common Mistakes

• Do not pick a cup just because it sits nearest the tap; sealed joints mean proximity does not decide which one fills.
• Drag the number 2 cup aside to uncover the pipe behind it, since it masks the outlet leading to cup 5.
• Trace the open route all the way to its final cup before entering a number, and check that the branch toward cup 6 is capped rather than assuming both right-side cups fill.
