HOW TO PLAY ROCKET LAUNCH PAD

In one paragraph

A rocket lifts off. A multiplier counts up from 1.00x. You bet FlapRocket before liftoff, and tap CASH OUT at any point during flight to lock in bet × current multiplier — paid as BNB equivalent. At a hidden, pre-committed point the rocket explodes — anyone still in the round loses their stake. Cash out before the boom.

Beat the rocket

Each round has a hidden crash multiplier — the moment the rocket explodes. The contract commits to this number on-chain before betting opens, so it cannot change once a round starts.

Your job: cash out at a multiplier at or below the crash point. If you cash out at 2.40x and the rocket crashes at 2.50x, you win. If it crashes at 2.39x, you lose your stake.

Three phases, ~12 seconds

1. PHASE 1 · 6s

   Betting Window

   Type a FlapRocket amount, optionally set an auto cash-out, click PLACE BET. The contract snapshots the FlapRocket→BNB rate at liftoff.

2. PHASE 2 · ~3-30s

   Liftoff & Climb

   The rocket fires. The multiplier rises smoothly: 1.00x → 1.25x → 1.80x → 3.00x → … Tap CASH OUT at any moment to lock the value on screen. Your auto cash-out target (if set) fires automatically when reached.

3. PHASE 3 · 3s

   Crash & Reveal

   Boom. The multiplier freezes at the crash point. The contract reveals the round seed; anyone can verify the result. Winners are paid instantly. The next round opens 3 seconds later.

What you see, what it means

From input to lift-off

1. Type or pick a bet. Use the chips for shortcuts: ½ halves, 2× doubles, 100/500 set fixed amounts, MAX uses your full balance.
2. (Optional) Set auto cash-out. Pick a target multiplier (e.g. 2.00x). If the rocket reaches it, you cash out automatically — even if you're tabbed away.
3. Press PLACE BET. The button shows BET PLACED · WAITING. Your stake is escrowed by the game contract.
4. Wait for liftoff. When the betting window closes, the round transitions to FLYING. You can no longer place or cancel a bet for this round — only cash out.

Lock in your multiplier

During FLYING, the action button turns green and pulses: CASH OUT. Tap it at any moment. The contract pays bet × current multiplier as BNB equivalent — the rate is the one snapshotted at liftoff.

There is no "partial" cash-out — you exit the round in full. You cannot re-enter the same round; the next bet you place will join the next round.

Hands-free exits

Set an Auto Cash-Out multiplier before the round starts. The moment the live multiplier touches it, the contract cashes you out — no clicking required.

You can still tap CASH OUT manually at any earlier point; doing so locks in a smaller multiplier (you can tighten, but not loosen, your auto target during flight).

Edge, payout, and odds

• House edge: ~3% There is roughly a 1-in-33 chance the rocket crashes instantly at 1.00x. This is the only mechanism the house uses to take its cut. There is no fee on payouts.
• Payout cap: 10000.00x An absolute cap baked into the contract. Crash points beyond it are clamped to this value.
• Probability of reaching M Roughly 0.97 / M. So a 2.00x cash-out wins ~48.5% of the time; 5.00x wins ~19.4%; 10.00x wins ~9.7%.
• Expected value For any cash-out target the long-run expected return is the same: about −3% per bet. Higher targets give you more variance, not more EV.

Don't trust — verify

Before each round opens, the contract publishes seedHash = keccak256(seed) on-chain. After the rocket crashes, the original seed is revealed. Anyone can re-hash it locally and confirm the match.

The crash multiplier is then derived from keccak256(seed, blockhash(commitBlock+1)) via a deterministic formula. The same input always yields the same output, and you can run it client-side to confirm the on-chain crash point.

1. Note the round's seedHash (committed at round start).
2. After crash, copy the revealed seed.
3. Hash the seed in any SHA-256 / keccak256 tool. It must equal seedHash.
4. Run the crash formula (in RocketCrash.sol or js/game.js) on the seed. It must equal the announced crash multiplier.

If any step fails, the round is invalid and you can call forceRefund() after the timeout — the contract returns every bet in that round, no questions asked.

Where the money flows

Every round, three transactions matter:

• commit(seedHash) — operator opens the round and locks in the future crash point.
• bet(amount, autoCashoutBp) — your stake leaves your wallet and goes into the game contract.
• liftoff() — the contract reads the FlapRocket → BNB price directly from the on-chain bonding-curve oracle and snapshots it for this round.
• reveal(seed) — operator reveals the seed; the contract pays winners in BNB and sends losing FlapRocket stakes to the treasury — all in one transaction.

If the operator goes silent for over an hour after liftoff, anyone can call forceRefund(roundId) and the contract refunds every bet in that round. There is no admin override that can freeze player funds.

There is no winning strategy. Here are useful habits.

• Pick a target before you bet.Decide your cash-out before the round starts. Adrenaline raises targets in flight — that's the trap.
• Use auto cash-out for discipline.It removes the "one more second" temptation. The button cashes you out at exactly the multiplier you committed to in advance.
• Past rounds tell you nothing.A streak of low crashes does not make a high one "due". Each round is independent.
• Set a session cap.Decide an amount you're willing to lose before you start. When it's gone, walk away.
• Don't chase losses.Doubling the next bet to recover doesn't shift expected value. It only shortens the time to bust.
