An image of an iPhone screen with a number of threes on the screen has become an internet sensation.
Thousands of people have viewed and deliberated over the photo, which has been widely shared along with the question: ‘How many threes can you see in this picture?’
If your answer is either 15, 19 or 21, you have arrived at the same conclusion as the majority of social networkers. But which answer is correct?
Can you count how many threes are on the iPhone screen? If you see 15, 19 or 21 number threes, you have arrived at the same conclusion as the majority of social networkers… but what’s the correct answer?
There are in fact 19 number threes pictured in the image, but there could be 21 depending on how you interpret the question.
Apart from the eight threes in the phone number, there are two threes on the key pad as the number eight button has been replaced.
At 3.33pm, the time also contains three number threes and the battery power at 33 per cent contains another two.
That totals 15, the answer many social networkers have come to. On closer inspection, however, there are a further four hidden digits, totaling 19.
Three of the letters in the contact’s name have been replaced with threes and the letter ‘I’ on the number four key has also been replaced.
But many online posts give the answer to be 21, with people seeming convinced that there are a further two threes in the image.
The differing opinions come down to the interpretation of the question. The images has been widely shared on Facebook and Twitter with the message. ‘How many threes do you see in this picture?’
Many users have included the bar signal and the wifi signal, both of which show three bars. But whether 19 or 21 is the correct answer is a matter of opinion.
The puzzle, which has been widely shared on Facebook and Twitter after resurfacing again online, has instigated heated debate, with may being totally flummoxed when others have arrived at a different answer.
Twitter user Dani posted: ‘This thing annoyed the hell out of me when someone said 21. I was like no there’s 18 until I looked again properly haha.’

Facebook Ravi Vidyadhar Pathak came to a grander total and said: ’28 if it’s saying to count everything that resembles to 3 including the network signal which is 3 dots the page info on left which is 3 the buttons having 3 letters ABC.’
Another philosophical Facebook user Marc Joseph posted: ‘I see only 2….and technically am correct cause you never asked how many 3’s are there in the pic.’
Athene Whitfield finally concluded the answer was 19 but had made so many previous guesses she posted: ‘I got to that in the end but thought – I can’t send an answer through again!!? Was getting embarrassed!’
One user by the name of Sarah was so involved in the problem she posted a mock-up of the screen with the potential answers highlighted in purple.
When a friend posted ‘Not sure where you get 20 from’ she posted: ‘Now I’m not sure.’
It follows optical illusion poster featuring tigers that resurfaced online this week, asking viewers to guess how many animals it featured.
On close inspection the picture has the felines hiding in the bushes, bark and even the sky.
The image, which appears to have been produced as a poster, has two adults tigers and their two cubs in the foreground.
But after those, it becomes trickier to track down the furry felines in the picture but there are 12 other tiger faces which are hidden.
The image appears to have been used as a poster but has resurfaced on the internet
In the foliage to the right of the tigers, there’s a fern in the shape of a tiger’s face, with two hiding in the dirt beneath the tigers’ feet.
In the top of the picture, there are five feline faces hidden within the branches of the trees.
While another two are seen in the wide trunk of the tree on the left of the picture and another tiger is face is seen on the left behind it and the last one is hidden in the soil below it.
The poster, which features 16 in total, appears to be aimed at children, like many of the logic puzzles which have stormed the internet in recent times.
Another recent brain teaser saw a children’s picture with tourists at a holiday campsite and challenged them to answer a list of nine questions.
The puzzle has the big cats hidden in foliage, trees and even the ground with all 16 very difficult to find
The image, thought to be from an old children’s magazine, according to The Independent, but despite being aimed at youngsters the tough questions are likely to leave adults scratching their heads
The black and white drawing showed three people at the campsite. One is standing by the cooking pot with a ladle, another is rifling through his backpack, and a third is taking photos.
A sign nailed to a tree states said: ‘On duty. Colin, 7. Peter, 8. James, 9’. The final name is obscured, but the number 10 is visible.
A picnic blanket with four plates, four spoons and a watermelon is laid out on the ground and a hen is scratching in the grass nearby.
Nearby, a tent is pitched and a spider has built a cobweb between the edge of the tent and a nearby tree.
A recent challenge which baffled the internet is a logic puzzle from an old children’s magazine that involves studying a picture of tourists at a holiday camp site and answering a list of nine questions
A series of clues is provided by the apparently calm scene involving boys at a campsite
The first question people are challenged to answer is how many people are staying at the camp.
They must also figure out whether they arrived that day or a few days earlier, how they got there and how far away the closest town is.
CAN YOU SOLVE THE PUZZLE BY ANSWERING THESE QUESTIONS?
1. How many tourists are staying at this camp?
2. When did they arrive: today or a few days ago?
3. How did they get here?
4. Is there a town nearby?
5. Where does the wind blow from: north or south?
6. What time of day is it?
7. Where did Alex go?
8. Who was on duty yesterday?
9. What date is it today?
*Scroll down for answers
In addition, they’re asked whether the wind is blowing from north or south and what time of day it is.
The next question is to state where someone called Alex went.
Finally, they must figure out who was on duty yesterday and what day of the week it is.
Unlike the many cartoons that have swept the web in recent months challenging the web to spot figures hidden in a sea animals or Star Wars characters, this puzzle relies on deduction.
The answer to how many tourists there are is relatively easy to figure out.
As there are four spoons and plates on the blanket and four names on the duty list, the answer is quite obvious.
The cobweb gives a clue to when the group arrived as it must have been a few days earlier to give the spider time to build it.
An oar leaning up against the tree is the key to figuring out how they got there – by boat.
The hen indicates that the nearest town is not far away as it’s managed to wander into the campsite.
Hungarian cartoonist Gergely Dudas, also known as Dudolf, posted his latest puzzle a few days ago to celebrate Easter, challenging fans to find an egg cleverly disguised alongside a group of bunnies
The egg is cunningly disguised between a pair of white rabbit ears in the second row on the left hand side
ANSWERS TO THE CAMP RIDDLE
1. There are four tourists
four spoons on the picnic blanket and four names on the duty list.
2. They arrived a few days ago
A spider’s web has appeared between their tent and a tree in that time.
3. They got there by boat
Note the oars by the tree.
4. No, a village is not far
..because there’s a chicken wandering around.
5. The wind is blowing from the south
A flag that shows the wind direction is on top of the tent. (To tell which direction is which, look at the branches – they’re normally bigger on the southern side of trees – if you’re in the Northern Hemisphere.)
6. It’s morning
Take the answer from question five to figure out east and west then work out the time based on the shadows.
7. Alex is catching butterflies
His net is behind the tent.
8. Colin was on duty yesterday
Colin is rummaging through his backpack (marked with a ‘c’); Alex is catching butterflies; James is taking photos as his tripod can be seen sticking out of his bag. This leaves Peter – then, according to the list, that means Colin was on duty yesterday.
9. Today is August 8th…
According to the list, Peter is on duty, and there is a watermelon – which ripen in August – on the ground.
A flag on the tent, known as a windsock, shows that the wind is blowing from the south, but to figure this out you need to be aware that branches on the southern side of trees in the UK get more sun and grow more densely.
To figure out the time, you need to use the previous answer which tells you south from north to figure out where is east and west and deduce the time based on shadows.
The answer is that it’s morning because the boy by the cook pot’s shadow extends to the west.
Because we’re asked where Alex went, we can assume he’s not visible in the picture. However a butterfly net can be seen behind the tent. So the answer is that he’s gone to catch butterflies.
Gergley’s original spot the panda puzzle left the internet baffled at Christmas 2015
The original Where’s Wally-style snowmen picture was liked by 42,000 people and shared 100,000 times within days, with many struggling to find the panda at all
Dudolf followed up the panda puzzle days later with another picture posted online, this time of a cat hidden among dozens of brightly coloured owls
He planted a few red herrings in the owl picture like a colourful bow tie and festive hats, but the owl’s facial features make it particularly difficult to spot the cat
To figure out who was on duty yesterday first consider that Colin, Peter, James and Alex are staying at the camp.
We know that Alex is catching butterflies and the person taking photos must be James, as there’s a tripod sticking out of the bag marked J.
The person looking through the backpack is Colin as it’s marked with a C.
That means Peter must be the one standing by the cooking pot. If Peter is on duty today, then according to the list on the tree Colin was on duty yesterday.
Figuring out the day of the month isn’t too tricky as according to the duty list it’s the 8th of the month.
But establishing what month it is may prove rather more difficult. The solution lies in the watermelon on the picnic blanket.
The answer is the 8th of August, but you would have to be aware that it’s the month in which watermelons ripen to find the correct answer.
Its long list of questions makes the puzzle even more baffling than a challenge by Gergely Dudas who first drove the internet mad trying to find a panda among a group of snowmen, and a cat blended into rows of owls.
The Hungarian cartoonist posted his latest puzzle a few days ago to celebrate Easter, challenging fans to find an egg cleverly disguised alongside a group of bunnies.
The panda craze was followed up by Reddit contributor, with the username Oneste, who created a mind-boggling puzzle in which he hid a panda amongst rows and rows of Stormtroopers – and TIE fighter pilots
The black and white Star Wars image made it especially tricky to find the panda
