Glossary
Definitions for terms that appear in our studio-led UK casino comparisons.
UKGC
The UK Gambling Commission licenses and regulates commercial gambling in Great Britain. Licensed operators must meet standards for fairness testing, customer fund protection, and responsible-gambling tools.
RNG
A Random Number Generator drives outcomes in digital slots and virtual table games. Licensed software is tested by independent labs to confirm results are unpredictable and unbiased.
RTP
Return to Player is the theoretical percentage a game pays back over millions of spins. A 96% RTP slot still produces losing sessions in the short term — it describes long-run maths, not a session guarantee.
Volatility
How swingy a slot's payouts are. High-volatility games pay less often but can produce larger hits; low-volatility games return smaller wins more frequently.
Wagering requirement
The number of times you must bet bonus funds (sometimes deposit plus bonus) before withdrawing winnings tied to a promotion. Always check game weightings.
Live casino
Real dealers streamed from studios — typically Evolution, Playtech Live, or Pragmatic Live — running blackjack, roulette, baccarat, and game shows with physical cards and wheels.
Game studio
The software company that builds a title. NetEnt, Pragmatic Play, and Blueprint are studios; Grosvenor or NYSpins are operators that license those games for UK players.
GamStop
A free UK self-exclusion scheme covering all licensed online operators. One registration blocks access across brands for your chosen period.
Megaways
A licensed reel mechanic (originally Big Time Gaming) where each spin can change the number of symbols per reel, altering ways to win. Many studios license the engine for their own themes.
Affiliate link
A tracked URL that tells an operator a visitor arrived from a comparison site. United Slot Cabinet may earn commission if you later register; it does not change our scores.
