I don't understand how to install this mod, how to do a MYSQL Query or how to make a single page that runs it.

I want a "Game Station" page under explore that has image links to various minigames' own pages. Slot machine being one.

This mod is for v1.2.x.

Old mods are not going to work in the newest version of Mysidia without significant changes. Even if I tell you how to make the table in the database (open up phpMyAdmin, open the SQL tab, and copy and paste the query given by the OP), you still won't be able to use this mod as-is. Someone will have to open it up, look it over, and bring the code up to date.

Ah. Well it was the database thing and where to put the slotmachines images and folder that was troubling me the most. I'm quite happy to have a fiddle and see if I can upgrade the php myself.
