Welcome bonus: Kosmonaut Casino runs a tiered first-deposit offer for new players: a 100% match up to €300 on the first deposit, then 50% up to €200 on the second, and 25% up to €200 on the third. The match bonus typically carries a 35x wagering requirement, and you need to opt in before depositing. A common minimum deposit for the promo is €20, and the bonus funds usually expire after 7 days if you don’t meet the playthrough.
Free spins: Free spins are often bundled into the welcome package, for example 100 spins on a selected slot (credited as 10 spins per day over 10 days). Winnings from free spins are commonly added as bonus money with a 35x wagering requirement, and a max cashout cap such as €100 applies until you complete wagering. The spins usually have a short use-by window (often 24 hours after credit), and only count on the specified game.
Cashback and promotions: Kosmonaut Casino regularly posts weekly cashback, for example 10% on net losses up to €200, credited on Mondays, with a 10x wagering requirement and a €20 minimum loss to qualify. Ongoing promotions include reload bonuses (e.g., 50% up to €100 on weekends), slot tournaments with fixed prize pools (e.g., €5,000 across a leaderboard), and time-limited “happy hour” boosts on selected games. Current bonus terms depend on the promo page at the time of claiming, since eligible games, caps, and wagering can change from week to week.
A wagering requirement (also called a “wager” or “playthrough”) is the total amount you must stake on eligible games before Kosmonaut Casino lets you withdraw bonus money and any winnings made from it.
Open the site, tap Sign Up, enter your email and a password, then confirm your email link. If you want faster withdrawals later, complete identity verification right after registration.
Tap Log In in the top menu, then use “Forgot password” to get a reset link by email. The link expires, so request a new one if it stops working.
Yes—Kosmonaut Casino runs in a mobile browser, so you can play through Safari or Chrome. If your phone blocks pop-ups, allow them or the cashier pages may not open.
E-wallet payouts usually clear the same day after approval, while card and bank withdrawals take 1–3 business days. Delays happen when verification is incomplete or when the casino asks for extra documents to confirm the payment method.
Yes, the cashier accepts Visa and Mastercard, and the minimum deposit starts from €10. Your bank can still decline the charge if it blocks gambling-related transactions.
Choose the bonus in the cashier or promo section before you deposit, then meet the wagering requirement shown in the bonus terms. Most bonus money can’t be withdrawn until wagering is completed, and some games contribute less than slots.
Open your account bonus area and look for the progress bar or remaining amount. If it doesn’t update, log out and back in to refresh the session.
Use live chat for account and payment questions, and email support if you need to attach documents or screenshots. Keep the transaction ID from your cashier history so support can trace it faster.
Kosmonaut Casino accepts deposits from £10 up to £5,000 per transaction. The casino applies the same deposit ceiling across cards and e-wallets, while bank transfer deposits follow the same range but can take longer to appear on the balance.
Withdrawals start at £20 and go up to £10,000 per transaction. A daily cap of £20,000 applies to total withdrawals across all methods, so multiple cashout requests made on the same day are counted together against that limit.
