Although you get a lot of chips this way, it’s both time consuming and tedious.
The usual process for me is go to the Free Pop Slots Chip page, make sure the app is closed, and if not, force-close it, click on the latest Pop Slots link, collect those chips, force-close the app, and repeat until all the available, non-expired links have been collected. One of the most frustrating aspects of collecting free Pop Slots Chips is that it’s buggy! Sometimes it doesn’t collect properly, sometimes it says it’s expired, and even if it does work, you have to force-close the device after clicking on every free Pop Slots chip link!
