The ultimate crash game on Polygon. Place your bet, watch the multiplier rise, and cash out before it crashes. It's simple, transparent, and provably fair.
BustaBit is a multiplier crash game built on the Polygon blockchain. Each round, a multiplier starts at 1.00x and rises over time. It can crash at any moment — at 1.01x, at 5.00x, at 100.00x, or anywhere in between.
Your goal is simple: cash out before the crash. If you cash out at 3.00x, your bet is multiplied by 3. If the multiplier crashes before you cash out, you lose your bet.

WIN Scenario
You bet 10 USDC. The multiplier climbs to 2.50x. You click Cash Out at 2.50x. You receive 25 USDC — a profit of 15 USDC.
LOSS Scenario
You bet 10 USDC. The multiplier reaches 1.80x. You wait for a higher number, but it crashes at 1.85x before you click. You lose your 10 USDC bet.
You need a crypto wallet to play. We recommend MetaMask — it's the most popular Ethereum wallet and works great with Polygon.
Click the 'Connect Wallet' button in the top-right corner of BustaBit. MetaMask will pop up asking you to approve the connection.
After connecting, you'll sign a message to prove you own the wallet. This uses Sign-In with Ethereum (SIWE) — an industry-standard authentication method.
Before your first bet, you'll be asked to approve USDC and USDT. This is a standard ERC-20 approval that lets the game contract collect your bet when you place one.
Once approved, you're ready to play. Enter your bet amount, click 'Place Bet' during the betting window, then watch the multiplier and cash out at the right time.
Yes. Connecting your wallet is completely safe.
We understand the concern. There are many scam sites out there, and you should always be careful. Here's exactly what happens when you connect, and why it's safe:
Read-only connection
When you connect, we can only see your public wallet address — the same address anyone can look up on Polygonscan. We cannot see your private key, seed phrase, or initiate any transactions.
You approve every transaction
Every single action that involves your tokens — approvals, bets, everything — requires your explicit confirmation in MetaMask. We cannot move your tokens without you clicking 'Confirm' in your wallet.
No custody of your funds
BustaBit is non-custodial. Your tokens remain in YOUR wallet until the moment you place a bet. Winnings are sent directly back to YOUR wallet. We never hold your funds in between.
Revoke anytime
You can revoke token approvals at any time using tools like Revoke.cash or directly through Polygonscan. You can also disconnect your wallet from BustaBit at any time.
Open-source & on-chain
All transactions are publicly visible on the Polygon blockchain. You can verify every bet, every payout, and every round outcome independently.
Security Tips
Every game round goes through a fixed sequence of phases. Understanding these phases helps you make better decisions about when to bet and when to cash out.
A new round begins. You have 10 seconds to place your bet. During this time, the server has already committed to the crash point by publishing a hash of the server seed. This proves the outcome was decided BEFORE any bets were placed.
The betting window closes. No more bets are accepted. The multiplier is about to start climbing.
The multiplier starts at 1.00x and climbs steadily. It updates 20 times per second for a smooth visual experience. This is where the excitement happens — watch it climb and decide when to cash out!
The multiplier hits the pre-determined crash point and stops. If you haven't cashed out, your bet is lost. The crash point could be as low as 1.00x (instant crash) or as high as thousands.
All bets are settled. Winners receive their payouts directly to their wallets on Polygon. The server seed is revealed so anyone can verify the round was fair.
The multiplier represents how much your bet is worth right now. If you bet 10 USDC and the multiplier is at 3.50x, your current value is 35 USDC. But this value is only real if you cash out before it crashes.
| Multiplier | 10 USDC Bet | Profit | Approx. Chance* |
|---|---|---|---|
| 1.50x | 15.00 USDC | +5.00 | ~64% |
| 2.00x | 20.00 USDC | +10.00 | ~48% |
| 3.00x | 30.00 USDC | +20.00 | ~32% |
| 5.00x | 50.00 USDC | +40.00 | ~19% |
| 10.00x | 100.00 USDC | +90.00 | ~9.7% |
| 50.00x | 500.00 USDC | +490.00 | ~1.9% |
| 100.00x | 1,000.00 USDC | +990.00 | ~0.97% |
*Approximate probability the round survives to this multiplier (with 3% house edge)
Cash out at 1.5x — 2.0x
Small but frequent wins. You'll win roughly half the time or more. Good for conservative players who want steady results.
Cash out at 3.0x — 5.0x
Bigger wins, but less often. You'll win roughly 1 in 3 to 1 in 5 rounds. A balance between excitement and reasonable returns.
Cash out at 10x+
Rare but massive wins. You'll lose most rounds but one big win can be very rewarding. Only for players who understand and accept the risk.
Unlike traditional casinos where you must trust that the games are fair, BustaBit uses cryptographic proofs so you can verify every single round yourself. No trust needed.
Before the Round
The server generates a random server seed and computes its SHA-256 hash. This hash is published before any bets are placed. This commits the server to a specific outcome. The server cannot change the seed after publishing the hash.
Crash Point Calculation
The crash point is derived from HMAC-SHA256(serverSeed, clientSeed:nonce). This is a deterministic function — the same inputs always produce the same output. The server cannot manipulate the result after committing to the seed.
After the Round
The server seed is revealed. You can now verify that (a) hashing the revealed seed matches the pre-published hash, and (b) running the crash formula produces the exact crash point shown. Visit our Verify page to check any round.
This means: we literally cannot cheat. The math is public, the seeds are published, and anyone in the world can verify every round independently. This is the gold standard of online gaming fairness.
BustaBit uses stablecoins — USDC and USDT — which are pegged 1:1 to the US Dollar. This means 1 USDC = $1 USD, always. No price volatility while you play.
USDC is issued by Circle (backed by US Treasury bonds and cash). USDT is issued by Tether. Both are the most widely used stablecoins in the world.
Polygon is a Layer 2 blockchain that offers near-instant transactions with extremely low fees (fractions of a cent). This makes it perfect for a fast-paced game like BustaBit.
Compared to Ethereum mainnet where a transaction might cost $5-50, Polygon transactions cost less than $0.01. Your gaming experience is faster and cheaper.
Connect your wallet, approve your tokens, and place your first bet. The next round starts in seconds.
