Competition Terms — Ball Knowledge

JD Sports voucher prize draw · Terms version 8 November 2026

In short: it is free to enter. You need a free Ball Knowledge account with a confirmed email, 10 completed daily games (on at least 2 different days), and to be 13 or over and living in the UK (under 18s need a parent or guardian’s permission). Each valid entry is one chance in a random draw for a £50 or £20 JD Sports voucher. Friends you invite who also become valid signups earn you more entries. These terms are the full rules.

1. Who runs this

The promoter is Ball Knowledge (ball-knowledge.com) (“we”, “us”). You can contact us through the Contact page. This competition is not sponsored, endorsed or administered by, or associated with, JD Sports Fashion Plc or any of its group companies. “JD”, “JD Sports” and the JD logo are trademarks of their owners and are shown only to identify the prize. Entering means you agree to these terms.

2. Free to enter, who can enter

No purchase is necessary and there is no charge to enter or to play any Ball Knowledge game. To enter you must be 13 or over and resident in the United Kingdom, and must make one account for yourself. Only one account per person may enter. If you are under 18 you must have the permission of a parent or guardian to enter; by ticking the boxes you confirm that you have it. If an under-18 wins, we will arrange the prize with their parent or guardian, and the voucher will be given to the winner with the parent or guardian’s agreement. We may ask for reasonable proof of age, residence and permission from a winner.

3. Competition period

The competition opens at 00:00 on 8 November 2026 and closes at 23:59:59 on 31 December 2026 (UK time) (the “Competition Period”). Only games played within the Competition Period count towards entries.

4. How to enter

Create a free Ball Knowledge account (by email and password, or with Google).
Confirm your email address by clicking the link we send you. Accounts created with Google sign-in count as confirmed.
Complete at least 10 daily games while signed in during the Competition Period, on at least 2 different days (see section 5).
On the competition page, tick the boxes confirming you are 13 or over (and, if under 18, have a parent or guardian’s permission), live in the UK and accept these terms, and press “Enter the draw”. You can do this at any time before the competition closes; games count from 8 November whenever you enter.

5. What is a “valid” signup

An account is a “Valid Signup” only when all of these are true:

it belongs to one real person, who made it themselves, and is the only account that person uses to enter or to be counted;
its email address has been confirmed (see section 4);
it has completed at least 10 daily games, on at least 2 different days, during the Competition Period. A “game” means one of the daily games on the site completed to the end once on a given day while signed in; the same game on the same day counts once, and a game left unfinished does not count; and
it has not been created automatically, in bulk, by a script or by anyone paid or otherwise rewarded to create it, and has not been used to give anyone an unfair advantage.

You are not a Valid Signup until all of these have been met. We decide from our records whether they have been, and we may check them at any time.

6. Entries

Your own entry. Once you have entered the draw (section 4) and your own account is a Valid Signup, you have 1 entry.
Entries for friends you invite. Every account that (a) was created through your personal link from the competition page, (b) was created within the Competition Period and (c) is a Valid Signup earns you 1 extra entry. The link must be used when the friend creates their account; it cannot be added afterwards, and you cannot refer your own account or another account you control. A friend you refer does not need to enter the draw for your extra entry to count, but they need to enter themselves to have their own entry.
There is no limit on the number of entries you can earn this way. You must have entered the draw yourself for your friends’ entries to count for you.
Entries are worked out from our records at the time of the draw. Entries that are not yet valid when the competition closes do not count.
You can withdraw from the competition at any time from the competition page.

Share your link only with people you know and only where doing so complies with the law and the rules of the platform you are using. Do not send unsolicited bulk messages or post it as spam. We do not send messages to your friends on your behalf.

7. Prizes

1st prize: a £50 JD Sports voucher. 2nd prize: a £20 JD Sports voucher.
One prize per person. There is no cash alternative. Prizes cannot be transferred and are subject to the voucher issuer’s own terms and expiry date.
If a prize is unavailable for any reason we may replace it with one of equal or greater value.

8. The draw and the winners

After the competition closes, and within 14 days, we will draw two different winners at random from the Valid Signups who have entered, so that each entry is one equal chance. The first name drawn wins the £50 voucher and the second wins the £20 voucher. We will also draw reserve winners. The draw uses a random seed that we record so that it can be checked.

Before a prize is awarded we will check that the winner and the accounts they referred meet these terms. If any entry is found not to be valid we may remove it, and we may disqualify anyone who has broken these terms or has tried to cheat, and draw again from the reserves.

We will email each winner at the address on their account. If a winner does not reply within 14 days, or cannot be given the prize, or is disqualified, we may award it to a reserve winner. Vouchers will be sent by email or post within 28 days of the winner confirming their details. The winners’ display names are available on request via the Contact page. Our decisions on the competition are final, except where the law says otherwise.

9. Your data

We use your email address and account details to run the competition, confirm that entries are valid, contact winners and send the prize. If you sign up from a friend’s link, we record who referred you and a one-way, scrambled version of your connection address, which we use only to spot abuse, and we delete these records after the competition is finished. We tell your friend only how many invitees have become Valid Signups and how many games each has played, never your name or email address. We do not use your email for marketing unless you ticked the box to hear from us. See our privacy policy for full details and your rights.

10. Other

We may cancel, change or suspend the competition if something beyond our reasonable control means it cannot run as planned, and will say so on this page.
We are not responsible for entries that are lost, delayed or not recorded because of technical problems, but will do all we reasonably can to make the site work.
Nothing in these terms limits our liability for death or personal injury caused by negligence, for fraud, or for anything that cannot be limited by law.
These terms are governed by the laws of England and Wales and the courts of England and Wales have non-exclusive jurisdiction.
