Depends on if you are on mobile, steam, or switch platforms. I will say, for mobile, you can earn ~32 pizza gems per day. You can earn:

• 20 from PNN ads

• 10 from WPA Sponsor ads

• 2 from daily quest

For mobile, you can also purchase gems from the store using real money,

How many minutes of ads is that though

Ads can vary in length. On average, each ad is 30 seconds. You are looking at roughly 15 minutes worth of ads. I also updated the total above.

@Sypes how are you getting 20 pnn ads?

That is just the amount that the game gives you. You get 2 ads after every PNN segment, even if the segment is that there is no news. You do have to play the game day though. If you quit the day, you may be delayed on what PNN presents to you.

@FLIPSTATIC ENERGY the PNN news diamonds won't get lost after you watch the ads and quit the game before any customers, if this helps
