Slots & Gaming Machines
Gambling slots
Gambling slots is a non-technical term for reel-based casino games where symbols on spinning reels determine prizes, including online and remote versions.
- Regulatory term
- UK guidance uses 'slots' for reel-based casino games, including non-traditional reels.12
- Online stake limit (GB)
- Maximum stake per game cycle: £2 for ages 18–24, £5 for 25+.3
- How it works
- Outcome determined by random-number generation mapped to reel stops at the moment of play.4
- Licensing
- Remote slots are treated as casino gaming under the Gambling Act 2005, not a separate licence type.1
Key points
- The term 'gambling slots' is not a distinct category in UK regulation; it refers to the same reel-based games as 'slots'.12
- Modern slot machines use random-number generation to determine reel positions, making each spin independent of previous results.4
- UK guidance classifies remote slots as casino gaming, meaning they fall under the same licence requirements as other casino products like roulette or blackjack.1
- The Gambling Commission defines slots as games where moving or changing symbols are displayed on reels or reel-like representations, and the player can win a prize from the resulting arrangement.3
