From Biribi to the modern roulette — a journey through centuries of gaming history.
Before the roulette wheel became the icon of casinos worldwide, there was Biribi — a game of pure chance born in Italy and adopted by the French aristocracy. Biribi is considered the direct ancestor of modern roulette, and it is from this historical game that biribi.net takes its name.
Biribi emerged in Italy as a lottery-style game of chance. Players would place bets on a board displaying numbers from 1 to 70. A small ball or token was drawn from a bag to determine the winning number. The game quickly gained popularity across Italian cities.
Biribi crossed the Alps and became immensely popular among the French nobility and in Parisian salons. It was known as a game of high stakes and excitement, attracting players from all social classes despite frequent attempts at regulation.
Biribi reached its peak popularity in France during the 18th century. The game was played in aristocratic homes, gambling houses, and underground establishments. Its simple yet thrilling mechanics — picking a number and hoping for a match — captivated players across Europe.
Inspired by Biribi's number-based betting system, French inventors began experimenting with a spinning wheel mechanism. The word 'roulette' — meaning 'little wheel' in French — was born. The wheel replaced the bag draw, adding a mesmerizing visual element to the game.
The first recognizable form of modern roulette appeared in Paris. The game combined elements of Biribi's number betting with the spinning wheel, creating the layout still used today: 36 numbers plus a zero, with the iconic red and black alternating pockets.
The French government officially banned Biribi along with other gambling games. The house advantage in Biribi was considered too high and the game too prone to fraud. This ban accelerated the transition to roulette, which offered more transparent and verifiable odds.
From Biribi's numbered board to biribi.net's smart contracts — the spirit remains the same: a fair game of chance, now made truly transparent and trustless through blockchain technology.
Transparent. On-Chain. Verifiable Every Round.
Every BRB wagered generates protocol revenue that is automatically split and distributed through smart contracts — no multisigs, no manual transfers, no discretionary decisions. The allocation is hardcoded into the protocol and executes autonomously every round. Anyone can verify the distribution on-chain at any time.
95%
Stakers Rewards
Automatically redistributed to all BRB stakers proportionally via the staking vault contract. Stake BRB and earn real yield from real protocol activity — not token emissions.
2.5%
Jackpot Pool
Feeds the on-chain global jackpot. Any player betting on a single number has a chance to win the entire pool. Growing continuously, paid instantly by smart contract.
0.5%
BRB Burn
Permanently burned on-chain, reducing total BRB supply forever. Every round makes BRB scarcer. Deflationary tokenomics driven by real usage, not artificial mechanisms.
2%
Infrastructure
Covers Chainlink VRF callback fees, RPC node infrastructure, frontend hosting, and protocol maintenance. Transparent operational costs — no hidden fees.
Every action on biribi.net earns you BRBP — play games, stake BRB, or refer friends. Climb from Bronze to Legend and spend your points on exclusive perks.
Play & Earn
Every BRB wagered earns game points with a x3 multiplier — the most rewarding source of BRBP.
Stake & Grow
Stake BRB to earn points over time. The longer you hold, the more you earn (staked × days).
Refer & Collect
Hold BRBR tokens from referrals to earn passive points with a x2 multiplier.
Yes. biribi.net is a protocol, not a platform. All game logic — bet placement, random number generation, payout calculation, revenue distribution — runs autonomously on Ethereum smart contracts. The roulette randomness is powered by Chainlink VRF with on-chain cryptographic proofs. There is no centralized backend, no admin panel, no server-side game logic. Nobody — not even the founding team — can alter a spin result, delay a payout, or freeze your funds. The contracts are deployed and autonomous.
Revenue distribution is hardcoded into the smart contracts and executes automatically every round: 95% goes to BRB stakers as real yield, 2.5% to the jackpot pool, 0.5% is permanently burned (reducing BRB supply), and 2% covers infrastructure (Chainlink VRF fees, nodes, hosting). This split is verifiable on-chain at any time — no multisigs, no manual transfers, no discretionary allocation.
Chainlink VRF (Verifiable Random Function) generates random numbers off-chain and delivers them with a cryptographic proof that is verified on-chain by the smart contract. This means every spin result is mathematically provable: you can verify on Etherscan that the random number was generated correctly. It’s the same oracle standard trusted by Aave, Compound, and major DeFi protocols. Nobody — not Chainlink, not biribi.net, not anyone — can predict or manipulate the result.
2.5% of every round’s revenue feeds into a global on-chain jackpot pool that grows continuously. Any player who places a bet on a single number has a chance to win the entire jackpot. When triggered, the payout is instant and automatic — executed by the smart contract with no human intervention. The jackpot balance is publicly visible on-chain at all times.
The core game logic — bet processing, randomness, payouts, revenue distribution — is immutable once deployed. The smart contracts are autonomous and execute exactly as coded. The revenue split (95% stakers, 2.5% jackpot, 0.5% burn, 2% infra) is hardcoded. The team cannot change the payout ratios, manipulate randomness, or access staker funds. This is the whole point of building on Ethereum: code is law.
BRBP is biribi.net's gamification system that rewards you for playing, staking, and referring friends. Points are earned from three sources: Game points (BRB wagered, weighted x3), Referral points (BRBR tokens held, weighted x2), and Staking points (staked amount × days, weighted x1). Your total BRBP score determines your tier and unlocks perks in the Perks Shop.
There are 6 tiers based on your total BRBP score: 🥉 Bronze: 0 BRBP (starting tier) 🥈 Silver: 500 BRBP 🥇 Gold: 2,000 BRBP 💠 Platinum: 5,000 BRBP 💎 Diamond: 15,000 BRBP 👑 Legend: 50,000 BRBP Your tier badge is displayed on your profile and in the account banner.
Most crypto casinos are traditional gambling platforms that accept crypto payments but run centralized backends. They control the RNG, manage your funds, and can change rules at will. biribi.net is fundamentally different: the entire game runs on Ethereum smart contracts with Chainlink VRF for randomness. Your funds never leave your wallet until you place a bet. 95% of revenue goes to the community. Everything is verifiable on-chain. It's the difference between a company and a protocol.
BRB staking rewards come from real economic activity — actual BRB wagered by real players. There are no inflationary token emissions, no unsustainable APYs, and no Ponzi dynamics. 95% of genuine protocol revenue flows to stakers proportionally every round. Your rewards auto-compound (no need to claim), and you can withdraw your stake plus all accumulated earnings at any time. This is real yield, not printed tokens.
0.5% of all protocol revenue is used to permanently burn BRB tokens on-chain. The burn is automatic, transparent, and verifiable. There are no inflationary mechanisms, no VC unlock schedules, and no new tokens being minted. The more the protocol is used, the more BRB is burned, and the scarcer the remaining supply becomes. Pure deflation driven by real usage.
Absolutely. biribi.net never holds your funds. There are no deposits into platform wallets, no accounts to create, no KYC requirements, and no withdrawal approvals. You connect your own Ethereum wallet (MetaMask, WalletConnect, Coinbase Wallet, or any Web3 wallet), and every transaction happens directly between your wallet and the smart contract. Your keys, your funds — always.
Ethereum is the most secure, decentralized, and battle-tested smart contract platform. It has the deepest liquidity, the largest developer ecosystem, and the strongest censorship resistance. biribi.net chose Ethereum because trust and security matter more than cheap transactions — especially when real money is at stake. Ethereum’s neutrality and decentralization are not just nice-to-haves, they’re the foundation of a truly trustless protocol.
There are three ways to earn BRBP: • Game (x3 weight): Every BRB you wager earns game points — the most valuable source. • Referral (x2 weight): Hold BRBR tokens from the referral program to earn referral points. • Staking (x1 weight): Stake BRB and earn points based on your staked amount multiplied by the number of days staked. Tip: Playing regularly is the fastest way to climb tiers since game points have the highest multiplier.
