Game design
What a licensed slot can’t do
The Gambling Commission’s technical standards (RTS 14) set how online games must behave.
No spins faster than 2.5 seconds
There must be at least 2.5 seconds between starting one spin and starting the next. You have to press and release the spin button (or take an equivalent action) each time.
No turbo, quick spin or slam stop
A game can’t let you speed up the time it takes to show the result. This applies to all online casino games.
No celebrating losses
A game can’t play win sounds or animations when you get back the same as, or less than, you staked.

A slot that lets you bet more than £5 a spin, or offers turbo spins, isn’t following UK rules. If you’re in Great Britain, that usually means the site isn’t licensed by the Gambling Commission. Here’s how to check a casino’s licence.
