The first number in the world.
Last updated: 06/10/2026.
Buck is the Flexo Buck fan point. It is used for the ranking and fan club perks.
Each number received credits, only once, the Buck amount below to the account that received it. The amount depends only on the number, and the number depends only on order of arrival.
The first number in the world.
From #2 to #9.
3 or more identical digits: 111, 888, 1111, 7777…
2 identical digits: 11, 22, 33… 99.
From #10 to #99.
Ends with 3 identical digits.
Buck can also be bought in the app Shop, via Pix: R$1 = 10 Buck. Your balance goes up as soon as the payment is confirmed.
The "Who runs it" ranking uses your current Buck balance: buy and you climb, spend and you drop. Ties go to the lower number. The official account (#1) does not compete. Top 1 takes the Throne: they can pick a link shown at the top of the lounge and the ranking, after review. Gambling, adult content, scams, piracy and pages asking for passwords or payments are rejected. When Top 1 changes, the Throne changes too.
Stickers are limited, numbered digital items, bought with Buck in drops or received by rare number holders. You can use them in the lounge, download them and sell them on the Market for Buck. On each sale, 5% is burned (removed from the system) and the seller gets the rest. Stickers and Buck cannot be traded for money.
The Shop also drops titles (some 1 of 1), avatar frames, name effects, 2–3 letter premium @ handles and Flexo shoutouts. Each item has a fixed supply, announced at launch, that never increases. Titles, frames and effects show in the lounge and ranking when equipped. A premium @ can be used as your nickname; if you sell it, your previous nickname comes back. A redeemed shoutout is delivered as a video within 30 days and can no longer be sold; if it can't be delivered, the Buck paid in the drop is refunded.
Numbers (except #1) can be sold on the Market for Buck, with the same 5% burn. The Buck a number gave when it was issued stays with its first owner; the buyer gets the number, the fan card and the badge. Selling your last number removes you from the lounge until you get another.
Some drops are physical products (t-shirts, caps and more), paid only in Buck, with free shipping, delivered only within Brazil. Stock is the number announced in the drop. Delivery takes up to 15 business days, and the tracking code shows in your Collection once it ships.
When you buy a physical item you choose: ship it to you or keep it in the vault. In the vault, we keep the item with shipping already paid, and it can be resold on the Market for Buck any number of times. Any owner can request delivery at any time. When someone takes delivery, that unit leaves circulation for good, and the app shows how many are still in the vault. If the vault ever closes, we give 60 days' notice for everyone to request delivery.
If you are short on Buck for a Market item, you can pay the difference with Pix: the amount becomes Buck in your account and the purchase completes automatically, with the item held for you for 20 minutes. Sellers always receive Buck, never money. If someone buys it first, the Buck stays in your account.
The Buck coin carries Flexo's face. In your wallet and on your public fan card it is engraved with your number and series (the batch letter). It is only your account's visual identity: your balance is still a single Buck balance.
Every fan also has a medal shaped like Flexo's head. Its metal depends on the rarity of your best number: bronze for common, silver for Pioneer and Lucky, gold for Epic and Legendary, pink for numbers 1 to 9. Special medals (solid gold, colored) may come in limited drops.
Holders of a rare number (#1 to 99 and repeated digits like 111 or 7777) get: a free profile photo, an animated ring in their medal's color, a highlight in the lounge, photo sending in the lounge, drops opening 1 hour early, a link on the public fan card and the rare-only exclusive items. Perks last while the number is yours: if you sell it, they go to the buyer.
Profile photos are for rare holders or Photo Pass owners. The Photo Pass is a limited Shop item that can be resold on the Market. If you sell the Pass, your photo stops showing. Every photo goes through an automatic AI check before it goes live: nudity, sexual content, violence, weapons, drugs, hate symbols, phone numbers, @ handles, QR codes and payment keys are rejected. Photos with 3 reports are taken down, and moderators can delete any photo. Only upload photos you have the right to use.
Rare holders can add one link to their public fan card. The link goes through the same filters as the Throne (betting, adult content, scams and URL shorteners are rejected) and can be removed at any time.
Rules and perks may change with notice on this page. Credited Buck is not removed, except for refunds, fraud or technical error.
