I just played Random and got 8,858 sP. Below that, it says Back To Game Room or Leave An Alert.

I've never seen this before. What does leaving an alert do? o_O

- If you click it it sends you an alert/reminder that you can play it again. Just like the training center :)

I think maybe it puts an alert in the right-side column, like a Mail alert?

So, when I click it, it'll give me an event when I can play again? That's cool! :D

Yep :) It will say Alert! You can now play random again and random is clickable :) Very handy

If you click on it, it will leave you a reminder of when you can play again.
