You may have seen that RS are trying to promote a new game through Steam, named as above.
I'm not going to go in to the concept but you basically spend a few minutes a day using points that you have gained - by not doing a great deal. These points allow either level up's or move workers on a particular skill, which in turn give's more points.
Anyway, here is a small script allowing you to leave the game running whilst afk yet still gain levels by clicking them.
Don't forget to select the RS Idle client from Simba!
