Go to 78mcom and click "Sign Up". Enter your full name, CPF, email, phone number, and date of birth. Registration takes under 2 minutes and is completely free — available exclusively to residents of Brazil aged 18 and over.
You'll receive a confirmation email from 78mcom. Click the verification link to activate your account. This step secures your registration and unlocks access to the welcome bonus.
Make your first deposit of at least R$ 20.00 via Pix. The credit hits instantly and the 100% bonus is applied automatically — no code needed. Boleto, card, and PicPay are also accepted.

Nubank, Itaú, Bradesco, Banco do Brasil, Inter, C6 Bank, and all Pix-enabled banks are accepted.
It's not just the amount — it's how the platform treats Brazilian players at every step of the process.
At 78mcom, the bonus doesn't require a manual request or approval. As soon as your Pix deposit is confirmed — which takes just seconds — the 100% bonus is automatically credited to your balance. No waiting, no hassle.
The 20x rollover on the bonus amount is one of the lowest among platforms operating in Brazil. The contribution percentage for each game is shown before you claim — no fine print hidden anywhere. 78mcom believes in full transparency.
The bonus works the same on the 78mcom app for Android and iOS and in the desktop browser. There are no device restrictions — start on mobile, continue on desktop, and your rollover progress syncs in real time.
The welcome bonus is exclusive to the first deposit per CPF. Creating multiple accounts won't work — 78mcom carries out rigorous identity verification to protect all members and uphold the platform's integrity.
After the welcome bonus, the promotions keep coming: a 50% weekly reload, VIP cashback, free spins every Wednesday, and tournaments with real cash prizes. 78mcom believes loyalty should be consistently rewarded.
Pix accepted, support in Portuguese, amounts in BRL, and special promotions for major Brazilian football events — Brasileirão, Copa do Brasil, Libertadores — and UFC. Everything built for players in Brazil, not adapted from another market.

Real experiences from players who claimed the 78mcom welcome bonus and made the most of the platform's promotions.
I deposited R$ 200.00 via Pix and within seconds my balance was R$ 400.00 with the bonus. No code, no waiting — exactly as advertised. I cleared the rollover in about 4 days playing Gates of Olympus and withdrew without any hassle. Best welcome bonus I've come across in Brazil.
What sold me was the 20x rollover — most platforms require 40x or more. I signed up at 78mcom, deposited R$ 100.00, and got to play with R$ 200.00 plus 50 free spins. The spins were credited right after my deposit — no need to request anything.
I love that the bonuses don't stop after the welcome offer. 78mcom has a reload every Friday and weekly VIP cashback. I'm already at Silver level and get 10% cashback on net losses — in Sports Betting, that makes a huge difference on football bets.
The welcome bonus is a betting platform's first impression on a player. At 78mcom, that impression was carefully crafted to be genuinely good — not just in the advertised value, but in every detail of the process: from sign-up to completing the rollover. The result is one of the most comprehensive bonus programs available to Brazilian players today.
The main offer is straightforward: a 100% bonus on your first deposit, up to R$ 500.00. That means a R$ 50.00 deposit gets you R$ 100.00 to play with. A R$ 200.00 deposit becomes R$ 400.00. At the maximum, a R$ 500.00 deposit gives you R$ 1,000.00 in available betting balance. And unlike many platforms that require a promo code or manual request, at 78mcom the bonus is credited automatically as soon as your Pix is processed — which takes seconds.
Along with the cash bonus, you receive 50 free spins on Gates of Olympus — one of the Pragmatic Play slots with the highest multiplier potential on the platform. Each spin is worth R$ 1.00, adding up to R$ 50.00 in extra rounds. Winnings from the free spins are subject to their own 30x rollover, but given the multiplier potential Gates of Olympus can deliver, that's rarely an issue.
The concept of rollover intimidates a lot of new players, but it's simpler than it sounds. At 78mcom, the welcome bonus rollover is 20x the bonus amount received — not your total balance. So if you deposited R$ 100.00 and received R$ 100.00 in bonus, the amount you need to wager before withdrawing is R$ 2,000.00 (R$ 100.00 × 20). Your original R$ 100.00 deposit isn't locked — you can withdraw that portion at any time. Only the bonus amount needs to be "turned over" before it becomes withdrawable balance.
Slots and crash games contribute 100% toward the rollover, meaning every real wagered on these games counts in full. If you enjoy playing Aviator, Spaceman, Gates of Olympus, or Sweet Bonanza — all available at 78mcom — you'll likely clear the rollover naturally over your regular gaming sessions.
The 30-day window to complete the rollover is generous. A good strategy is to spread your bets over the weeks, keeping them smaller and more frequent rather than trying to clear the rollover in a single day with large bets — which raises the risk of running out of balance before you're done.
A common mistake when evaluating platforms is comparing only welcome bonuses. At 78mcom, what comes after is just as relevant. The 50% weekly reload every Friday means that every week you can deposit and get half more to play with over the weekend — exactly when football is in full swing, UFC events are happening, and slots tournaments are live.
The weekly VIP cashback is arguably the most valuable perk for regular players. Calculated on net weekly losses (bets placed minus winnings received, excluding withdrawals), it's credited every Monday with a rollover of just 1x. At the Bronze level, the rate starts at 5%. Silver brings it to 10%, Gold to 15%, and Diamond — the highest tier in 78mcom's VIP Program — offers 20% cashback. For a regular player who loses R$ 500.00 in a rough week, getting R$ 100.00 back (20% cashback) makes a real difference to their gaming budget.
Every serious platform needs clear bonus rules, and 78mcom is no exception. Identity verification (submitting a photo ID) is required before your first withdrawal. This protects all members by confirming that each account belongs to a real person aged 18 or over — and prevents the bonus from being exploited through multiple fake accounts, which would undermine the sustainability of promotions for everyone.
The terms of each promotion are available on the platform before you claim, written in plain, straightforward English — no obscure technical jargon. 78mcom understands that an informed player is a more satisfied player, and that transparent rules are key to building trust.
To get the most out of the 78mcom welcome bonus, start by depositing the amount that unlocks the maximum bonus of R$ 500.00 — meaning a first deposit of R$ 500.00. With R$ 1,000.00 in total balance (deposit + bonus) plus 50 free spins, you'll have plenty of capital to work through the rollover comfortably over the course of the month.
Choose slots with high RTP and high volatility to clear the rollover faster — such as Gates of Olympus (96.5%), Sweet Bonanza (96.5%), or Aviator (97%). High volatility means there will be swings in both directions, and the multiplier potential in these games means a single lucky round can cover a significant chunk of the rollover. Keep your bets small — between R$ 1.00 and R$ 5.00 per spin — to make your balance last across more sessions.
Ready to get started? Create your account at 78mcom now, deposit via Pix, and the welcome bonus hits your balance automatically. Within minutes you'll be spinning Gates of Olympus with a doubled balance and 50 extra rounds. Brazil has serious players — and 78mcom has the bonus they deserve.
