Official rules

Last updated 30 October 2026

No purchase or payment is necessary to enter or win. Paying never improves your chances.

1. The promotion

Promotto is run by EGO HERO LLC (the "Sponsor"; "we" and "us" in these rules). The Sponsor is responsible for the promotion and for awarding any prize.

Promotto runs one race a day, posted as a video on Instagram at @promotto. Each race is a computer simulation of balls rolling down a course. The first ball over the finish line wins.

2. How to enter

• Comment on that day's race post on Instagram before the entry window closes. The post states when it closes.
• Each unique Instagram account that comments gets exactly one ball in the next race. More comments do not add balls.
• Entry is free. You need a public comment on a public Instagram account, and you must follow Instagram's own terms.
• We may leave out comments that are spam, abusive, automated, or from accounts created to gain extra entries.

3. Eligibility

Open to individuals who meet Instagram's minimum age requirement in their country of residence. If a winner is under the age of majority where they live, a parent or legal guardian must accept any prize on their behalf. Void where prohibited or restricted by law.

4. How the winner is chosen

• Before the entry window closes, we commit to a private random seed and publish its fingerprint. The seed decides the course and every ball's start.
• After entries close, the race is simulated once. The result cannot be changed afterwards. If a technical fault forces a re‑run, the post says so and why.
• When there are many entrants, qualifying heats run first and the final is shown in the video. Every entrant's place is published with the result.
• Every ball has the same chance of winning.

5. Ball customisation

We may let you choose a colour, a short label or a photo for your ball. Customisation is free and cosmetic only. It never affects the race or your chance of winning. Anything shown in a public video is moderated first.

6. Prizes and announcement

The winner is announced in the race video and its caption. Any prize for a given day is described in that day's post or on the promotto.app website. If a post describes no prize, the race is for fun and there is no prize. Prizes cannot be exchanged for cash.

7. Release of Instagram

This promotion is in no way sponsored, endorsed, administered by or associated with Instagram. By entering, you fully release Instagram and Meta Platforms, Inc. from any and all liability connected with this promotion. Questions about the promotion go to us, not to Instagram.

8. Your data

We use your Instagram username and comment to run the race. See the privacy policy for what we keep and how to have it deleted.

9. Changes and contact

We may update these rules. A change never applies to a race whose entry window has already opened. Send any questions to [email protected] and we will reply.
