Open odds
Return to player for every game, calculated from the paytables in the code. No rounding up.
| Game | RTP | House edge | Where the number comes from |
|---|---|---|---|
| Slots | 94.75% | 5.25% | Weighted reels (CASI 1, 7 2, Gem 3, Gold 4, Rocket 5, Frog 6 out of 21). About 21.9% of spins pay more than the bet. |
| Crash | 99.00% | 1.00% | The chance the round reaches x is 0.99 / x, so any cash-out target returns 99%. |
| Plinko | 98.91% to 99.12% | 0.88% to 1.09% | Each peg is a 50/50 bounce, so the slots follow a binomial curve. |
| Mines | 98.28% to 99.00% | 1.00% to 1.72% | Each multiplier is 0.99 times the fair odds, rounded down to 2 decimals. Depending on rugs and picks the return sits between 98.28% and 99.00%. |
| Dice | 99.00% | 1.00% | Payout is 99 divided by your win chance, so every target returns 99%. |
| Coin Flip | 99.00% | 1.00% | A 50/50 call that pays 1.98×. |
| Blackjack | 98.91% | 1.09% | With perfect basic play and no splits (6 decks, dealer stands on 17, blackjack pays 3:2). Worse play lowers it. |
| Coin Catcher | Skill | No bet | Coin Catcher is a skill game with no bet. You earn 1 chip per 10 points. |
Built on Solana
Casiho is a crypto arcade on Solana. Connect Phantom, Solflare, Backpack or any Solana wallet that supports the Wallet Standard; the site reads your public address and keeps your chips, XP and badges under it. If you've set a primary .sol domain, the header shows that name instead of the address.
On a phone, it runs inside the Phantom and Solflare in-app browsers.

FAQ
How do I get chips?
Connect a wallet, follow @Casiho_App and wait out the 15 second timer, then claim 1,000 CASI chips. The daily drop adds more every 24 hours, from 100 on day 1 up to 1,000 on day 7.
Do I need SOL for fees?
No. Playing never asks for a transaction signature or a fee.
Which wallets work?
Phantom, Solflare, Backpack and any other Solana wallet that supports the Wallet Standard. The picker shows each wallet your browser has, with its own name and icon. Casiho asks to connect and reads your public address; that's the only request it makes.
Can I play on my phone?
Yes. Open casiho.xyz in the browser inside Phantom or Solflare and connect there. If you land on the site in a regular mobile browser, the connect button offers to reopen it inside either app. You can also add Casiho to your home screen.
Are CASI chips a token?
No. Chips are a balance Casiho keeps in your browser, tied to your wallet address. Nothing about them is recorded on Solana.
How are results decided?
Every round draws from crypto.getRandomValues in your browser. Casiho has no game server, so rounds can't be audited after the fact; the odds table above lists the exact return of each game instead.
Why do I have to follow on X?
Following @Casiho_App unlocks your first chips and the refill when you run dry. We can't check follows without the X API, so the 15 second timer runs on trust.
What is Season 0?
Early access. All eight games, levels, badges and the daily drop work today, while tournaments and weekly challenges are still on the roadmap with no dates yet.
