I have been a long time never come across here. when I came before, only a few but now they have varied coins for deposit. they did hard for development.
As for the promotions and stuff, there are few currently ongoing promotion if you check this page https://chips.gg/events but yeah this thread should have been updated about it as well 
If the user doesn't have time to check the website. They should follow on twitter also to fast get the information about events and promotions.
