A TEA-RRIFICALLY hard coffee puzzle is sweeping the web — and people are losing their minds over it.
The brainteaser is made up of one funnel pouring into various pipes, which lead to four different coffee mugs.
Those doing the puzzle are challenged to find out which of the four cups — from 4 to 5, 7 and 9 — will get served first.
A picture of the brainteaser was posted on Twitter earlier this week, and thousands of people have attempted to solve it, so can you get it right?
It’s much harder than you think, with some thinking the cups would “all get it at the same time”, and others still getting it wrong despite meticulously studying the shape of the faucets and square containers.
While one frustrated bloke simply tweeted: “I’m out”. If you think you’ve cracked it, read on for the answer …
If you guessed number 5, then you’re correct. If you look closely, that cup is the ONLY one whose route to the cup isn’t blocked.
And people are absolutely flabbergasted, with Sulayman Zaraei writing: “how did I not notice that”.
The picture of the puzzle has gone viral, racking up more than 1,700 likes, 700 comments and 760 re-tweets since it was posted yesterday.
