A promo code is a short text code you enter in your Koi Casino account to unlock a specific offer. The offer can be a deposit bonus, free spins on a named slot, or a cashback deal tied to a time window. Each promo code has rules: a start and end date, an eligible payment method list, and a minimum deposit amount.
Koi Casino publishes promo codes in three places: account emails, SMS/push messages (if enabled), and the Promotions page inside your logged-in account. Some codes are one-time and linked to your profile, so a code from a friend can show as invalid even if the text looks correct. Codes can also be limited by country, currency, or a specific game provider.
Log in to Koi Casino, open the Cashier, choose Deposit, then look for the field labeled Promo code (sometimes shown as Have a code?). Paste the code exactly as written, check that the bonus name appears, then complete the deposit using an eligible payment method. If the bonus doesn’t attach, the usual causes are: deposit below the minimum, the code already used, the code expired, or the payment method excluded by the promo terms.
After the deposit, open the Bonuses section to confirm the bonus is active and read the wagering requirement and game contribution rules. If the code grants free spins, the spins normally appear in the selected slot’s free spins balance, and they expire on the date shown in the bonus details. Withdrawals stay blocked until wagering completes or you forfeit the bonus.
Koi Casino promo codes activate through the deposit flow and only apply when the deposit meets the code
A wagering requirement (also called a “wager” or “playthrough”) is the total amount you must bet before Koi Casino lets you withdraw money linked to a bonus. The required betting is calculated as (bonus amount + any bonus cash added) multiplied by the stated wagering number (for example, 35x).

| Table Games Player (Low Slot Weighting) | Cashback On Net Losses | 10% cashback up to $100 | No wagering (credited as cash) | Calculated weekly on settled bets; excluded: bonus buys and jackpots; table games count 100% for cashback; paid within 24 hours after the weekly cut-off. |
Open the Koi Casino site, tap Sign Up, and enter your email, password, and country, then confirm your email. If the site asks for verification, upload an ID and a proof of address to unlock withdrawals.
Tap Log In at the top of the page and use the same email you registered with. If the password fails, reset it from “Forgot password,” then check your spam folder for the reset email.
Koi Casino accepts common payment methods like Visa and Mastercard, plus selected e-wallets depending on your country. Deposits credit to your casino balance right after the payment clears, so you can start playing straight away.
Withdrawals take longer because Koi Casino runs account checks and payment processing before sending funds out. After approval, e-wallet payouts tend to be faster than bank-card payouts.
Go to the Promotions page, pick the offer you want, and follow the steps shown there before you deposit or enter a code. Koi Casino shows the wagering requirement and game restrictions in the bonus terms on the same promo page.
Koi Casino offers demo play on many slots, so you can test games without depositing. Table games and live casino titles usually require real-money play.
Open the menu in the top corner and look for Settings, Language, or Currency. If your account is already verified and active, currency changes can be locked to what you picked during registration.
Use the live chat button on the site for the fastest response, or send a message through the support email listed in the Contact section. Keep your transaction ID and the time of the payment ready so support can track it quickly.
