App & PWA Guide

Spinboss Casino does not have a native app in official app stores, but you can enjoy the full experience through a progressive web app (PWA). A PWA behaves like an app once installed from your browser. To install it:

• Important: Use Chrome on Android or Safari on iOS.
• Visit the website and wait for a banner or pop-up asking “Add to Home Screen” – tap it.
• If the banner doesn’t appear, open the browser menu and select “Add to Home Screen” or “Install App”.
• Once installed, the PWA launches in full-screen mode with faster loading and push notification capabilities.
• No app store download needed, and it updates automatically.

Welcome Offer Explained

New players at Spinboss Casino are eligible for a welcome package that typically includes a 100% match bonus on the first deposit up to a certain amount plus free spins. The exact offer may vary, so check the promotions page for current details.

Here is a worked example assuming you deposit €100 and the welcome bonus is a 100% match up to €200 with 50 free spins on a specific slot:

Note: The wagering requirement applies only to the bonus amount (€100) unless stated otherwise. You must wager €3,500 before any bonus winnings become withdrawable. Free spin winnings are usually credited as bonus funds with their own wagering requirements—read the terms carefully.

Worth Knowing

When choosing games, pay attention to the theoretical return to player (RTP) percentage. Video slots generally have RTPs between 94% and 97%, with some titles reaching 98% or higher. Look for games with RTP above 96% for better long-term value. Classic table games like Blackjack (with basic strategy) often have RTPs exceeding 99%, while European Roulette has about 97.3%. Avoid keno and scratch cards as they typically have lower RTPs (around 90–95%). Progressive jackpot slots usually have lower RTPs (sub-95%) because the jackpot contribution is taken out of the base game payout.

How long do withdrawals usually take?

Can I play on my mobile browser?

What documents are needed for verification?
