Slots Wiki

If you’re new to any subject it can be especially helpful to be able to access a list of those terms and phrases which are obvious to the familiar but can be a little odd for those who are not.  Online slots are no different and that’s why we’ve put together this comprehensive list of terms which we’ve called a ‘Slots Wiki’.  There was some argument over the title but this won out over ‘Slotspedia’, Slots Glossary’ and the slightly boring ‘Slots Terminology’ and perhaps we’ve invented a new term.

Anyway, read on to fill in the gaps in your knowledge about some of the more mysterious slots terms and phrases.
