Frequently Asked Questions
Do I really make a difference by playing FreeRice?
The rice you donate makes a huge difference to the person who receives it.
According to the United Nations, 25,000 people die every day from hunger or hunger-related causes, most of them children.
Though 10 grains of rice may seem like a small amount, it is important to remember that while you are playing, so are thousands of other people at the same time. It is everyone together that makes the difference. Thanks to you, FreeRice has generated enough rice to feed millions of people since it started in October 2007.

Why do I see some questions repeated?
Whenever you get a question wrong, FreeRice will repeat it a few turns later to give you a second chance at it.
Who pays for the donated rice?
The rice is paid for by the sponsors whose names you see on the bottom of your screen when you enter a correct answer. These sponsors support both learning (free education for everyone) and reducing hunger (free rice for the hungry). We thank these sponsors for their generous participation at FreeRice. For information about how you or your company can sponsor FreeRice, please email firstname.lastname@example.org.
How do I start playing FreeRice?
In the middle of the FreeRice Home page you will see something like:
To play the game, click on one of the four definitions (.little,. .old,. .big,. or .yellow.) that you think is correct. If you get it right, FreeRice donates 10 grains of rice to help end hunger. In the example above, you would want to click on .little,. which means .small.. You will then get a chance to do another word the same way. You can play as long as you like and donate as much rice as you like. When you are finished, you do not have to do anything.your donation is already counted.
How does the FreeRice program work?
FreeRice has a custom database containing knowledge questions at varying levels of difficulty. There are levels appropriate for beginners and levels that will challenge the most scholarly professors. In between are levels suitable for students of all ages, business people, homemakers, doctors, truck drivers, retired people. everyone!
FreeRice automatically adjusts to your level. It starts by giving you questions of increasing difficulty and then, based on how you do, assigns you an approximate starting level. You then determine a more exact level for yourself as you play. When you get a question wrong, you go to an easier level. When you get three questions in a row right, you go to a harder level. This one-to-three ratio is best for keeping you at the .outer fringe. of your skills, where learning can take place.
How is the difficulty level determined?
The program keeps track of how many people get each question right or wrong, and then adjusts each question.s difficulty level accordingly. So the questions at the easiest levels are the ones that people most often get right. The questions at the hardest levels are the ones that people most often get wrong. As more and more people have played the game, these levels have become increasingly more accurate.
What is the Options page?
On the Options page you can set FreeRice to remember how much total rice you have donated for the next time you play. Instructions are given at the bottom of that page.
What happens if my computer suddenly loses power while I am in the middle of playing? Does my donation still count?
Yes, once your screen says that you have donated a certain amount of rice, that means our servers have registered it. For example, suppose your screen says that you have donated 120 grains of rice. If your computer then suddenly loses power, or you close your browser, or you click to go somewhere else, your donation has already been counted.
How do I hear a word pronounced?
To hear one of the vocabulary words pronounced out loud, click on the speaker symbol to the right of the word. Speech over the Internet is not an exact science and there are a number of things you can check if you do not hear the word pronounced. Check that your computer has speakers, that the volume is turned up and not on mute, and that you have Flash installed (most computers do). Also, some recently added words may not have their pronunciations done yet. The pronunciations are very kindly provided by eSpindle.org, a non-profit organization that tutors vocabulary and spelling online.
Where does FreeRice get the word definitions from?
The word definitions for English vocabulary come from a wide variety of sources including dictionaries, thesauruses and books of synonyms. Each definition is double-checked and edited for accuracy. There are 60 levels of vocabulary with over 12,000 words in all, but it is rare for people to get above level 50.
How do you track the answers and rice donated for each person?
When you click on your choice for the answer, this information is sent to one of our servers via a regular HTML form. This form is then processed by the server using the PHP programming language, which then figures out if you got the answer correct and, if so, adds to both your personal rice total and the overall rice total. It then sends back an HTML page with new words and your new total as part of the next form.
If FreeRice has the rice to give, why not give it all away right now?
FreeRice is not sitting on a pile of rice.you are earning it 10 grains at a time. Here is how it works. When you play the game, sponsor banners appear on the bottom of your screen. The money generated by these banners is then used to buy the rice. So by playing, you generate the money that pays for the rice donated to hungry people.
Couldn't I just write a computer program to play all day and give a lot of rice that way?
There are two problems with this. First, it overloads our servers so that real people can't play and learn. Second, without real people playing and the resulting company sponsorship, no money would be generated and we could not give any rice at all.
Does FreeRice make any money from doing this?
FreeRice does not make any money from this. FreeRice is a website committed to the cause of ending hunger around the world. It is run entirely for free and at no profit. All money (100%) raised by the site goes to the UN World Food Program to help feed the hungry. Sponsors make all payments to the UN World Food Program directly.
What is the history of FreeRice?
FreeRice was founded in October 2007 by John Breen. In March 2009 Mr. Breen donated the site to the UN World Food Program. In making the donation, Mr. Breen expressed his hopes that FreeRice will be able to grow over the coming years, helping to feed and educate as many people as possible throughout the world.
Can you tell me more about the UN World Food Program (WFP)?
The UN World Food Programme (WFP) distributes all of the rice that you donate to help fight hunger. It is the United Nations frontline agency in the fight against global hunger and the world's largest humanitarian organization, working closely with many other organizations in over 75 countries.
In addition to providing food, WFP helps hungry people to become self-reliant so that they escape hunger for good. Wherever possible, they www.wfp.org.
In what countries does the UN World Food Program distribute the rice?
The UN World Food Program works around the globe and FreeRice donations are made with no restrictions. This freedom of use allows them to apply the donations to countries that need it most, often those that don't make the headlines in the news, yet where chronic hunger continues unchecked.
Often World Food Programme is able to purchase the rice in the very countries where the beneficiaries are located, cutting down on the transport time to reach the hungry and helping to stimulate local economies at the same time.
Here are some examples of where FreeRice rice has been distributed:
* In Bangladesh, to feed 27,000 refugees from Myanmar for two weeks. Watch FreeRice being distributed in Bangladesh.
* In Cambodia, to provide take-home rations of four kilograms of rice for two months to 13,500 pregnant and nursing women.
* In Uganda, to feed 66,000 school children for a week.
* In Nepal, to feed over 108,000 Bhutanese refugees for three days.
* In Bhutan, to feed 41,000 children for 8 days.
* In Myanmar, to feed 750,000 cyclone affected people for 3 days.
How much rice does it take to feed a person for a day? How many grains of rice in a gram?
The composition of UN World Food Program food basket varies from country to country and region to region, depending upon the eating habits of the people WFP feeds.
In countries where rice is a staple part of the diet, World Food Programme provides, on average about 400 grams of rice per person, per day (for families, including children and adults). That is intended for two meals that include other ingredients to ensure a minimum of 2,100 kilocalories per day.
There are about 48 grains of rice in a gram.
How does the food prices crisis affect FreeRice?
The cost of rice per metric ton has more than doubled since the website's inception. Given that FreeRice players raise grains of rice,not dollars, this increase does not change the overall number of people fed.
However, FreeRice donates the cash equivalent of the grains raised through sponsorships and donations, so rising rice prices means that FreeRice has to raise significantly more money to pay for the grains generated by every correct click.
Why has the number of grains donated for each correct answer changed from 10 grains to 20 and then back to 10?
When FreeRice started in October 2007, we gave 10 grains of rice for each correct answer. We were then fortunate enough to be able to increase this to 20 grains for 2008.
Unfortunately, we then had to decrease this to 10 grains again in January 2009 as a result of the global economic crisis and its effect on internet advertising. When the economic climate improves, we hope to be able to increase it once again.
