21 Casino Review 2026
Table of Contents
21 Casino Overview
21 Casino opened its doors in 2017 under the AG Communications Ltd umbrella, a Malta-based operator that also runs Karamba. The site leans into its blackjack theme with a dark, sleek design but the real draw is the breadth of its slot catalogue and the speed at which it processes withdrawals. For UK players, the dual UKGC and MGA licensing provides a reassuring compliance foundation.
Ownership And Trust Context
Operated by AG Communications Ltd, a Malta-based company with a track record running multiple licensed casino brands across Europe including Karamba Casino.

Welcome Bonus Deep Dive
Decent Mid-Tier Value
The 121% rate is a marketing quirk tied to the brand's blackjack theme — in practice you're getting just over one-to-one matched. The 35x wagering sits at the industry average. It's a fair offer but not the most generous on the market.

Player Reviews
SpinVerdict Verdict
Good
21 Casino is a reliable mid-tier operator that punches above its weight on withdrawal speed and mobile usability. The 121% welcome bonus is a fun brand touch, though the 35x wagering is nothing special. For UK slot fans who value quick cashouts and a tidy interface, it's a strong choice.
Best For
- • Slot players wanting a large, well-organised game library
- • Players who prioritise fast e-wallet withdrawals
