Birthdays are about sweets, cake, balloons, and lots of fun with your friends. Add presents to that list and suddenly the whole day gets brighter. Make them gifts a surprise and it’s tough to contain the excitement. So, we thought we would include all of that in our month long birthday celebration, for our 8th anniversary.
We started with a cool and calm celebration by devouring cake and pizza with our everhungry team members. But as stated, that was just a start. We have planned a whole lot more for you and us all. Some cool new developments on the website, some new developments for you, some new prizes, some new categories, and some surprises which will unveil themselves when the time is right. So, should we get the celebration started? We think we should.
New Goodies:
When we say “nothing excites us more than new stuff,” we think we speak for us all. We thought we will introduce some “new goodies” to our collection and offer you an even wider range to redeem your laddus.
So, what are these new goodies that we speak of, you ask? Well, let us list them down for ya.
 3Doodler Create 3D Pen

 GoPro Hero5 Black Camera
 GoPro Karma Drone
 Motorola Moto 360 Sport
 Oculus Rift – VR Headset

Head over to https://goodies.codechef.com/ and check out the latest additions to our goodies list in detail.
New Prize Categories:
It’s another “new” for you all. In our attempt to encourage programming talent from a wider pool, we have introduced some new prize categories on top of our existing ones. So now, we will see a lot of new programmers getting their hands on CodeChef goodies for the first time, some even multiple times. Now, let us introduce you to the new categories.

Random Laddus: Every rated contest, 5 participants will be randomly selected, and they will get 200 Laddus.

100% attendance participation reward: If a user participates (ie. solves at least 1 problem; and even partial solutions are counted) in each of CodeChef’s monthly contests (Long Challenge, CookOff, Lunchtime) in any 12 month period, then they will get 1000 Laddus. That is, if at any point, a user has participated in the last 36 CodeChef Monthly contests (ie. all the three contests in each of the last 12 months, except for some of the unrated contests), then they will get 1000 Laddus.
Contests before March 2017 will not be counted. Once the prize has been claimed, the counter will be reset. Problem setting panelists are considered to have participated.
So mark your calendars!

First one to solve each of the problems individually: In each rated contest, the first person to solve each problem (100%) will get 100 Laddus.
Tiebreaker problems are excluded.

Country wise:
a. Participation:
 In each rated contest, if there are at least 50 (and < 100 ) participants from a particular country (excluding India), then the top 10 from that country will get 30 Laddus.

If there are at least 100 (and < 200) participants from a particular country (excluding India), then the top 20 from that country will get 40 Laddus.

If there are at least 200 participants from a particular country (excluding India), then the top 30 from that country will get 50 Laddus.
b. Performance:
 In each rated contest, if there are at least 10 (and < 20 ) participants from a particular country (excluding India) who finish in the top 300 in the Global Ranklist, then the top 10 from that country will get 200 Laddus.

If there are at least 20 (and < 30 ) participants from a particular country (excluding India) who finish in the top 300 in the Global Ranklist, then the top 10 from that country will get 250 Laddus.

If there are at least 30 participants from a particular country (excluding India) who finish in the top 300 in the Global Ranklist, then the top 10 from that country will get 300 Laddus.
So go get all of your friends to participate and enjoy the rewards together!
Note: A user can get Laddus from at most one of the above two events. And In case there is a tie and more than 10 (or 20 or 30) people come in the top 10 (or 20 or 30), then the people who tied for the last qualifying rank will not be eligible. That is, not more than 10 (or 20 or 30) people will be eligible for laddus, and so if there are ties at the end, the number of people eligible could be less than 10 (or 20 or 30).
 Consistently in Top 10: If a user appears in the Top 10 of the Global Ranklist for 6 consecutive CodeChef monthly contests (ie. Long, CookOffs and LunchTimes), then they will get 2500 Laddus.The streak will be reset once the prize is claimed.
Note: Users who have been caught cheating will lose 50% of their Laddus, or 500 Laddus, whichever is higher.
Update: Since the introduction of the Rating Division System, there are some minor changes in the Laddus system, and is detailed here.
So, is that it for the celebration?
Well, not exactly. We have just started. We have a huge starstudded colorful present waiting for you just around the corner. So, keep watching this space and be the first one to get your hands on your presents as and when they are unwrapped.
With that, we will put our party hat back on and head over to where the celebration is: our contests. You too join us there and have fun.

Very nice initiative. Happy to see this post.
Thank you. We are glad too. 🙂
Here it’s said ‘excluding India’ so what about participants from India?
For participants from India, there are other opportunities mentioned here: https://discuss.codechef.com/questions/51999/howdoiwinacodechefgoodie
The links are broken 🙁 for the goodies.
very interesting
We hope you like it.
Best of these are 100% attendance and first to solve prizes. I have solved the first problem at first a lot of times including this march challenge and participate in all lunchtimes and long challenges. Will now also try to take part in cookoffs.
Wow. This is awesome.
Thanks! This makes us happy 🙂
Will the laddus be updated now for each new rule or will all the rules will apply after this month?
The mentioned prize categories/rules will apply for all the challenges beginning from March 2017.
All the rules will be applied with each contest starting this month.
“100% attendance participation reward: If a user
participates (solves at least 1 problem) in each of CodeChef’s monthly
contests (Long Challenge, CookOff, Lunchtime) in any 12 month period,
then they will get 1000 Laddus.” Does that mean maximum we will get 1000 laddus in an year?
No, you can earn more than 1000 laddus. The mentioned prize category entitles you to get additional 1000 laddus if you maintain 100% attendance in all our monthly contests for a span of 1 year.
No this is on top of what you get.
If I did participate in all the 3 competitions for consecutively 12 months will I get 12000 laddus
you will get 1000
@codechef:disqus
will it include partial score also?
First line says:
If a user participates (ie. solves at least 1 problem; and even partial solutions are counted)
Thanks…BTW this line was added because of my question in codechef discuss:)
Really good post and exciting prizes…..
I have one query regarding 100% attendance…will it include partial score(atleast 1 problem) in lunchtime and long contests??
First line says,
If a user participates (ie. solves at least 1 problem; and even partial solutions are counted)
Does the 100% participation reward include external rated contests?
No prize for participants from India for “Country wise” category?
Not clear about “First one to solve each problem individually”…
if someone is the first person to solve some problem completely,and not each problem,will he get laddus?
The Laddus will be automatically added or i will have to claim that after the contest..
This make participation more exciting. Now, I will try to participate in every codechef challenge.
How to get laddus by finding bugs?
In 100% attendance participation reward what is meant by this statement “each of CodeChef’s monthly contests in any 12 month period”? does it mean any 12 months after the reset whether consecutive or not.
yes.. it is just what you mean to ask…, provided the 12 moths you are counting are consecutive…
Here it’s said ‘excluding India’ so what about participants from India?
This is now turning from great learning to great participation, competition and excitement.. Awesome.!!
Are lunchtime laddus only for school students or also for college students?
In the coding competition yesterday, i got a global rank of 94, but still id dint get any laddus. Why? please check
when will bottles come?
It will come by next week
I have participated in all three contests every month from march 2017 to feb 2018, but my codechef laddus profile doesn’t show any transaction about it. How do we claim laddus for this?
I am logged in codechef using google+ account still it is showing that you need to login on goodies website of codechef
