Not a raffle. Pure aim.
Everyone offers an amount in secret. At the end we look only at the amounts that appeared exactly once, and the lowest of those takes the prize.
The rule here is simple
Say the campaign closed with these bids. The audit throws out every repeated amount and keeps the lowest of what is left.
- R$ 0,014 people bidrepeated
- R$ 0,022 people bidrepeated
- R$ 0,031 person biduniqueTakes the prize
- R$ 0,053 people bidrepeated
- R$ 0,071 person bidunique
R$ 0.01 and R$ 0.02 are out because they were repeated, even though they are cheaper. The winner is the lowest amount nobody else picked.
The lowest bid does not always win. The lowest unique bid always does.
In this example campaign, four people already bid R$ 0.01. That amount is burned. Pick an amount on the board and see what would happen to your bid.
Dead on!
R$ 0,04 is the lowest amount nobody else picked. You would take the prize paying exactly that.
Illustration only. In real campaigns other people's amounts stay hidden: you only see whether YOUR bid is unique.

Frequently asked questions
1. What is a lowest unique bid?
It is the lowest amount offered that no other participant offered. Being the lowest is not enough: if two people bid R$ 0.01, that amount is eliminated and the contest moves to the next amount that appears exactly once.
2. How much does it cost to take part?
The standard pack costs R$ 9.99 by PIX and gives you 7 bids on the campaign you choose. You can buy as many packs as you want, up to 50 packs per CPF per campaign.
3. How do I know my bid is unique?
On the campaign page, the My bids panel shows the status of each of your bids in real time: unique or repeated. You never see other people's amounts, only whether yours was matched.
4. Can I cancel or change a bid?
No. Once confirmed, a bid is final and goes into the audit. So think before you fire: every bid is one shot.
5. Can I place the same amount twice?
No, and it is for your own good: two identical bids from the same participant would cancel out that amount. The system blocks the repetition automatically.
6. When is the winner announced?
The moment the clock hits zero, the campaign goes into audit. Once it is done, we publish the winning amount and the audit summary on the campaign page, and the winner gets a confirmation e-mail.
7. What if nobody has a unique bid?
If every amount offered was repeated, the campaign closes with no winner, that is recorded in the audit, and participants' credit turns into a discount toward a Na Mosca product.
8. How do I pay for the product if I win?
You receive a PIX charge for the exact amount of your winning bid. Once it is paid, the product ships at our cost and you follow it with the tracking code.
9. What if my bid does not win?
What you spent on packs becomes 100% credit once the campaign is settled. It works as a discount toward a Na Mosca product, at the reference price we announced, it stacks across campaigns and never expires. It is not refunded in cash.
10. Who can take part?
Individuals aged 18 or over, with a valid CPF and a complete profile. One CPF per account. Duplicate accounts, or accounts with mismatched data, are disqualified.
11. Is this gambling?
No. The result does not come from a draw: it comes from how strategically you choose your amount. Na Mosca operates as a commercial promotion under the applicable Brazilian law, with public rules and an audited result.
12. Which payment methods are accepted?
PIX only for now, both to buy bid packs and to pay for the product you win.
One good shot costs R$ 9.99.
Seven bids, one target. Log in, pick your campaign and aim at the number nobody had the nerve to choose.
Open to adults 18 and over. Read the full rules before taking part.
