FORTUNA
Fortune favours the bold
The non-custodial casino on the Kaspa blockchain. Provably fair, no accounts, no KYC. Your funds are always yours — the built-in Fortuna wallet is a throwaway wallet created and encrypted on your own device; we never hold, touch, or have access to your money. Every spin is a real on-chain transaction, and winnings pay out in seconds.
⚡
Fortuna session wallet — the default. A throwaway wallet created in your browser, like a stack of chips: the key is generated on your device and encrypted with your PIN (Argon2id) — it never touches our servers. Load a few KAS, spin instantly on any device, sweep the rest out whenever you like. Save the backup key in case you forget your PIN.
🧩
KasWare — your own wallet (desktop). Prefer the self-custody wallet you already use? Connect the KasWare extension and approve each spin yourself. Fortuna never sees your key either way.
🔒
Custody, plainly. The house holds no deposits and no balances. A bet is a direct on-chain transfer; winnings are paid straight back to the address you played from, usually in seconds. There is nothing for us to hold, freeze, or "process".
🎲
Provably fair. Every outcome is locked by a published commitment before you bet — you can recompute any spin yourself.

How Fortuna works

Fortuna is a single-game casino built on the Kaspa blockchain. The fastest way to play is the built-in session wallet: create it in one tap, load a few KAS like buying chips, and spin — no account, no download, no extension, on any device. Each spin is one transaction signed by you; the outcome is fixed the moment it confirms on the public ledger, and winnings return on-chain within seconds. There are no deposits and no custody: you can sweep your session balance back to your own wallet at any time. Prefer your own wallet? Connect KasWare on desktop for one-click play, or scan the payment code from any compatible Kaspa wallet.

Provably fair · commit & reveal

Fortuna is provably fair, not just "trust us". Before any spins are played, the house publishes a commitment — the SHA-256 fingerprint of a secret seed — so it's locked in and can't be changed afterwards. Each spin's result is then derived deterministically from your own transaction hash combined with that secret. When the round closes, the house reveals the secret: anyone can confirm its fingerprint matches the original commitment, then recompute every spin and verify the payouts were honest. The house cannot see your transaction and then pick a seed that makes you lose — the seed was committed first. Use Verify a spin in the header to check any result.

Your funds & your safety

You stay fully sovereign: your keys never leave your wallet, and you approve every single spin. The Fate Vault (jackpot) grows from a small share of each stake until a lucky spin claims it. The Sanctum Reserve is the house treasury that backs every payout — shown live so you can always see the funds standing behind the game; maximum payouts are bounded by it. We never ask for personal data, email, or KYC to play. Stakes are exactly 1, 5 or 10 KAS — any other amount sent to the house address is not returned. What you see on-chain is what you get.

The reels · symbols & paytable

Fortuna is a 5×3 slot with 10 fixed paylines, evaluated left-to-right from reel 1. Each of the 15 cells is drawn independently from the same weighted reel strip, so every spin is a fresh, independent event. The seven symbols, rarest first, pay per line for 3, 4 or 5 matching in a row (multiples of your total stake):

Symbol Reel weight ×3 ×4 ×5
Crown2 / 426×50×250×
Coin3 / 424×30×130×
Hourglass4 / 422.5×15×75×
Star5 / 422×10×40×
Laurel7 / 421.5×6×22×
Dice9 / 421.2×4×13×
Key12 / 421×3×10×

"Reel weight" is how many of the 42 positions on each reel strip carry that symbol — rarer symbols pay more. All five reels use the same strip.

Return to player (RTP) & the odds

Fortuna's slot engine has a base RTP of ≈ 96.6%, with the progressive jackpot adding roughly 1% for a combined return of about 97.6% — meaning over a long run the game returns about 97.6 KAS for every 100 KAS staked, and keeps ~2.4% as the house edge. This figure is a mathematical property of the paytable and reel weights above, not a setting we adjust, and you can confirm it yourself: recompute the expected value from the weights and multipliers, or replay thousands of verified spins through the fairness tool. The Fate Vault jackpot triggers at fixed odds of 1 in 1,000,000 per spin, independent of the reels, funded by 1% of every stake and held in its own dedicated on-chain wallet (linked above) so it is always fully covered and payable. RTP describes the long-run average — any single session can swing far above or below it.

Non-custodial by design · your funds are yours

Fortuna never holds, touches, or has access to your money. The built-in Fortuna session wallet is a throwaway wallet generated entirely in your browser and encrypted on your own device with your PIN (Argon2id) — the private key never reaches our servers. You fund it like a stack of chips, and you can sweep the balance back to your own wallet at any time. Prefer your own wallet? Connect KasWare and approve each spin yourself. Either way, you sign every transaction and we never see your key. There are no deposits, no balances we custody, no withdrawals to request — a bet is a direct on-chain transfer and a win is paid straight back to the address you played from.

Network fees & settlement

Every bet and every payout is a real Kaspa transaction, so each carries a tiny network fee (a small fraction of a KAS, set just above the node's minimum relay fee). You pay the fee on your bet from your own wallet; the house pays the fee on your winnings. Nothing is pooled or held off-chain: a spin is a direct transfer to the house address, and a win is paid straight back to the address you played from, usually within seconds. Stakes are exactly 1, 5 or 10 KAS — any other amount sent to the house address is treated as a non-bet and is not returned, so always stake one of the three valid amounts.

Play responsibly. Games of chance carry risk — only stake what you can afford to lose. If gambling stops being fun, step away. Must be of legal age in your jurisdiction. New to Kaspa? Buy KAS · Get KasWare
