In more detail

A good slot site is judged on four things beyond its licence: how many slots it carries and from which studios, which RTP versions of those slots it runs, how its welcome offer treats slot players, and how quickly it pays. Our slots score follows the first; the reviews cover the rest. Coral, Ladbrokes and PlayOJO are level, so between those three the welcome offer is the fairest tie-breaker.
