Which Cup Fills First?

At first glance, this puzzle looks tricky because several pipes seem to lead to different cups. But if you carefully follow the water’s path, only one cup can actually receive water first.

Step 1: Follow the Water

Water begins flowing into the top container and then moves through the connected pipes.

The trick is to look carefully at which paths are open and which ones are blocked.

Step 2: Eliminate the Blocked Paths

Cup 2: The pipe leading toward Cup 2 is blocked near the top, so no water can reach it.

Cup 3: Its route is interrupted before the water can flow down into the cup.

Cup 4: The small pipe leading into this section is blocked, stopping the water.

Cup 5: Since the right-side route is blocked before reaching the final branch, Cup 5 also stays empty.

Step 3: Find the Open Path

The left-side pipe remains completely open and leads directly to Cup 1.

Water can travel through this route without meeting any blockage, so Cup 1 receives the water first.

✅ Correct Answer: Cup 1

Many people get distracted by the longer and more complicated pipe network in the middle and on the right. However, the simplest open route is the one that leads to Cup 1.

The secret is to trace every pipe carefully and check each connection one by one.

Did you get Cup 1, or did this puzzle fool you? 😄
