Arithmetic on the UK stake limits, not a record of wins.

What the figure means

A ceiling, and a remote one. Developers rarely publish the chance of reaching it. What it does show is the slot's shape: a very high maximum has to be paid for with long stretches of small returns.

How the big wins happen

Slot	What has to happen
Sweet Bonanza	Large multiplier bombs added together in free spins
Gates of Olympus	Cumulative multipliers in free spins
Book of Dead	The top symbol expanding on all five reels
Fishin' Frenzy	Many fishermen with high-value fish
Fluffy Favourites	Top symbols in tripled free games
