Colossus Bets
Colossus Bets is a London-based pool betting provider founded in 2012, licensed by the UK Gambling Commission (account 31514) and credited as the pioneer of Cash Out technology.
Rather than a slot studio, Colossus Bets builds pool betting and cash-out mechanics for sportsbooks and racing platforms, a niche product suited to bettors who want partial exits mid-event rather than fixed-odds wagers.

Colossus Bets Casinos — Games, Fairness and Where to Play
Colossus Bets is a pool betting provider, not a slot or table-game studio in the conventional sense. Its products centre on pooled wagers, jackpot bets and partial cash-out mechanics rather than reels or live dealer tables, which shapes what a player should expect from any casino or sportsbook that lists it.
Who Is Colossus Bets
Colossus Bets was founded in 2012 and operates out of the United Kingdom, according to its official website (https://www.colossusbets.com). The operator holds a licence from the UK Gambling Commission under account number 31514, with the exact remote operating licence recorded by the regulator as 031514-R-314905-020, per colossusbet.uk.com. Its chief executive is Bernard Marantelli, as reported by Yogonet in a 2019 licensing article.
Beyond its home licence, Colossus Bets holds a totalizator licence from the Oregon Racing Commission, obtained in 2019 according to Yogonet, allowing North American betting operators to connect to its horse racing pools through its own microsite technology. That expansion made Colossus Bets the first operator to offer Cash Out on racing pools in the United States, per the same report.
Games and Signature Mechanics
Colossus Bets' signature mechanic is partial Cash Out on pool bets — the ability to lock in a return before an event or race series concludes rather than waiting for the full result. Industry coverage describes Colossus Bets as "the pioneer of Cash Out," a claim tied to its 2018 partnership with Matchbook on a slot-style cash-out product called Fortunes of Arabia, according to igamingsuppliers.com.
The provider's broader portfolio includes jackpot-style pool betting launched with Mr Green in 2018, partial cash-out technology built for Tote Ireland on horse racing pools in 2015, and Mega Margin pools betting deployed with Ladbrokes for Australian and National Rugby League matches in 2015. These are pooled-stake products, structurally different from a slot's fixed paytable, and its lotto-sized jackpots combine leg-by-leg Cash Out with crowdfunded syndicates on racing, as described by Yogonet.
RTP, Volatility and Fairness
Colossus Bets does not publish an RTP or volatility profile in the way slot studios do, because its core products are pari-mutuel pools and cash-out bets rather than reel-based games with a fixed payout table. Fairness for this type of product rests on licensing and pool mechanics rather than a certified RNG return figure.
Colossus Bets operates under a UK Gambling Commission remote operating licence (031514-R-314905-020, account 31514), the same regulator that oversees consumer protection standards for operators marketing to UK players.
Where to Play Colossus Bets Games
The casino selection above this article lists operators in our catalogue where Colossus Bets products are available; Play Fortuna is currently the entry carrying it, holding a Curaçao licence, with 13 active bonuses offering wagering from 20x and match up to 175%. Colossus Bets sits at position 508 of 512 providers in our catalogue ranked by number of casinos carrying them, with a single listed casino behind it. For scale, Hacksaw sits near the top of that same ranking with 126 casinos carrying it, while providers at the bottom of the list — including Colossus Bets, Jili, D-Tech and Black Pudding Games — are each carried by a single casino.
- Availability — confirm the casino's live product page actually lists Colossus Bets pool or cash-out markets before signing up.
- Licence — check which regulator covers the specific casino, since license standards differ from Colossus Bets' own UK Gambling Commission authorisation.
- Region — pool betting products can be geo-restricted independently of the casino's general licence.
- Cash-out terms — read how partial cash-out is priced before an event settles, since this is not the same mechanic as slot volatility.
For readers comparing where to open an account, the Trusted Casinos hub and the New Casinos directory cover licensing and track-record checks that apply regardless of which provider a casino carries, and the Play Fortuna review details the one operator in our catalogue currently listing Colossus Bets.
Common Misconceptions
- "Colossus Bets is a slot studio" — it is a pool betting and cash-out technology provider; its products are pari-mutuel pools, not reel-based slots.
- "Cash Out means guaranteed profit" — cash-out pricing reflects the pool's current state and offered rate, not a fixed or favourable return.
- "A UK Gambling Commission licence guarantees a specific win rate" — the licence covers conduct, fund protection and consumer standards, not a promised payout.
- "Pool bets behave like fixed-odds bets" — payouts on a pool depend on how other participants staked, which differs fundamentally from a fixed-odds or slot paytable.
Verdict on Colossus Bets
"Colossus Bets is a pool betting specialist built around cash-out mechanics, better suited to bettors who understand pari-mutuel pricing than to players looking for a conventional slot catalogue."
Colossus Bets fits a narrow player profile: those who follow racing or sports pools and want the option to exit a position before settlement, under a UK Gambling Commission licence dating to a 2012 founding. It is not the choice for a player seeking slot mechanics, RTP tables or live dealer games, and the single listed casino in our catalogue reflects how niche that product remains within the wider online casino market.
Gambling is entertainment, not a way to make money or fix finances. Set deposit and time limits, take regular breaks, and use self-exclusion tools if play stops feeling like fun. Licensed operators provide these tools — using them is a sign of control, not weakness. Learn more on Responsible Gambling →
