I loaded 31bets on a Pixel 7 and an iPhone 13 over one weekend, and the lobby opened in under four seconds on 4G both times. The 31bets app keeps slots, live tables and the cashier in a bottom menu, so your balance sits one tap away. A provider filter lets you jump to Pragmatic Play or Evolution titles. The layout feels cramped on screens under 6 inches, and the terms for each promotion sit two taps deep in the offers tab. Those flaws aside, I found the same game count on mobile as on desktop, and I never needed to switch back to a laptop.
The 31bets app download for iOS needs iPhone or iPad software version 15 or later. On home Wi-Fi the install took me about 90 seconds. The process takes five steps:
Registration asks for your name, date of birth and address, and the cashier stays locked until you finish. After my first login I switched on Face ID in the settings menu, which saved me typing a password at every session. Blackjack and roulette tables rotate to landscape, and that suited my thumbs better than portrait. Apple sandboxes the app, so it cannot read other files on your phone.
You install the 31bets Android APK from the official website, so your phone needs permission to accept apps from outside Google Play. Open Settings, find the Security menu (Samsung phones list it under Apps, then Special access), and allow your browser to install unknown apps.
Android asks for storage and notification permissions on first launch. Grant storage so the app can save updates. Notifications are optional, and I switched them off. Download the file from the 31bets site and nowhere else, because a copy from a third-party forum can carry malware.
Here is the annoying part: the APK does not update itself the way a Play Store app does. I missed a version once and the app refused to open until I downloaded the new file. Check the site every couple of weeks, and keep 300 MB free before you update.
31bets matches your first deposit 100% up to £200 and adds 50 free spins. The wagering requirement is 35x on the bonus, so a £50 bonus means £1,750 in bets before you can withdraw. Slots count in full. Table games count for 10%, which makes blackjack a slow way to clear it.
Check the maximum bet rule before you spin. With bonus funds active, the cap is £5 per spin, and a single bet above it can void your winnings. Free spin winnings carry the same 35x requirement, which caught me out the first time.
The 31bets app took 15 seconds to load twice during my testing, and both times a weak signal on the train caused it. Switch to Wi-Fi or move to a spot with better coverage, then force-close and reopen the app. If an update fails, check your storage, since a new version needs about 300 MB free to unpack. Delete unused apps or photos and retry. Compare your Android or iOS version with the minimum listed on the download page as well.
My one login failure came from a mistyped password. Tap Forgot password, enter your email, and 31bets sends a reset link within a minute or so. If the error persists, uninstall and reinstall the app. Your account and balance sit on the server, so you lose nothing.
Live chat sits in the app menu. My first question got a reply in about two minutes, slower than I like, but the agent fixed a missing free spins credit in one session. Email suits longer problems such as a document upload, and my reply arrived the next morning.
