Which Coffee Cup Will Fill First?

At first glance, this coffee puzzle looks confusing. With multiple pipes branching in different directions, it’s easy to assume the coffee will reach several cups. However, once you carefully inspect each connection, only Cup 2 has a clear path.

Step 1: Follow the Coffee

The coffee starts pouring into the center container at the top before entering the pipe system.

Instead of following every pipe at once, trace each branch individually and look for any blocked or disconnected sections.

Step 2: Eliminate the Wrong Paths

☕ Cup 1:

The left branch appears open at first, but the pipe leading toward Cup 1 is blocked before the coffee can reach the cup.

☕ Cup 3:

The vertical pipe above Cup 3 looks connected, but the flow is interrupted by a blocked junction, preventing any coffee from reaching it.

☕ Cup 4:

Although the right-side pipe extends toward Cup 4, its connection is cut off by the blocked chamber in the upper-right section. No coffee can continue through.

Step 3: The Only Open Route

The only uninterrupted path runs through the left chamber and down the vertical pipe leading directly to Cup 2.

There are no blocked connections along this route, allowing the coffee to flow freely until Cup 2 fills first.

✅ Correct Answer: Cup 2

Many people choose Cups 1, 3, or 4 because the pipe network creates an optical illusion. The trick is to ignore the complicated layout and carefully inspect every junction for hidden blockages.

Once the blocked paths are eliminated, Cup 2 is the only possible destination.

Final Answer: 🏆 Cup 2
