Who Owns Proper Bet and Its Sister Sites?
Even after reviewing Proper Bet, it seems that not a great deal is known about the owners behind the casino, aside from the fact that they operate from a base in the English city of York. Proper Bet is licensed and approved by the UK Gambling Commission (#100990).

Proper Bet Sister Sites Timeline
Proper Bet was launched in the UK in August 2026, delivering a sports-casino hybrid via the Playbook Engineering platform. This makes them one of the newest entrants in the platform network.
Proper Bet vs Sister Sites Comparison
The Proper Bet sister sites, so to speak, have the same general layout and design, with a unique skin and visuals for each. Mind you, their game libraries differ quite markedly…

By and large, all Proper Bet sister sites have both sportsbook and casino games. Bet St George is another brand that seems to focus strongly on sports betting, aside from Proper Bet. The RTP and house edge differ from casino to casino despite using the same platform solution.
Game Library Analysis
At the time of writing, Proper Bet has only just launched, and we suspect their game library is yet to be fully formed.

Of their Playbook stablemates, the range is significant: from Bet St George’s minuscule selection of 86 games to StarSports’ near 2,500 strong library.
Slots are the mainstay of the Playbook, erm, playbook, so don’t expect a huge collection of table games and live casino titles at the Proper Bet sister sites – nor will you get a particularly intuitive search filter like volatility, with name and provider typically the only parameters available.
While limited, there are also a handful of titles in the Crash/Instant game categories. So there is something for everyone on these sites.
Unique Feature Analysis
Drops & Wins are the focal point of the Proper Bet sister sites promotions, although there’s a handy ‘Casino Club’ promo at AK Bets, which provides rewards when you stake specific amounts per week.
Of the other brands, London Bet and BetWright are two of the most interesting with their Capital Gains and Bangers N'Cash loyalty programmes. You’ll get rebates on your staking each week in the shape of free spins, free bet credits and more.

Proper Bet Sister Sites Withdrawal Times
We’re still taking a good look at Proper Bet and testing out its withdrawal speeds. Hopefully, it follows in the footsteps of its Playbook sister sites, as these brands are generally quite fast at completing payouts.
For example, London Bet processed our Visa withdrawal instantly, while AK Bets took a still-rapid six minutes and PricedUp took just under 40 minutes. Other Playbook brands take a little longer, but the general theme is quick withdrawals across the board.
Proper Bet Sister Sites - Our Verdict
Otherwise, we can recommend some of their sister sites if you’re looking for immediate action: StarSports leads the way in terms of pure gaming quality and quantity.
London Bet gets a thumbs up as well for its quick withdrawals and loyalty programme, while AK Bets’ Casino Club is another way to add value to your play.
