Casumo is a UKGC-licensed casino app available on iOS and Android. With an iOS App Store rating of 4.3 stars and an Android rating of 4.1 stars, it scores 4.5/5 in our independent assessment. The app loads in an average of 2.0s on a 4G connection — fast by UK standards — and the download size is 110 MB on iOS and 74 MB on Android.

The welcome bonus is 100% up to £25 + 20 Spins with a 10x wagering requirement and a minimum deposit of £10. This sits at the January 2026 UKGC maximum wagering cap, which is fully compliant. At a 4% house edge across typical slot games, the expected value of the welcome bonus is £15.00.

Beyond the standard welcome offer, Casumo offers an app-exclusive bonus: Reel Races — app-first access. This is only available to players who use the mobile app, not the desktop browser version.

Game Library

Casumo offers 3,000+ games accessible from the mobile app. The app includes a full live casino section with roulette, blackjack, and baccarat tables streamed in real time — all accessible on 4G without buffering issues in our tests. The app is casino-only — there is no sports betting section.

Payment Methods and Withdrawals

Deposits are accepted via Visa debit, Mastercard debit.

Withdrawal processing time is 0–24 hours. For verified accounts, withdrawals are typically processed well within this timeframe. We strongly recommend completing KYC immediately after registration — not when you want to withdraw — to avoid any delays.

App Features

Casumo supports dark mode for OLED battery saving.
