I just claimed the free 50 gems directly from the Facebook page.....even though I don't have a Facebook account.
If one link above doesn't work....try the other link
I just noticed that a pop-up window inside the game appeared but I had already claimed them.
If you are still having issues collecting your free 50 gems.....then I suggest that you contact Pixel support directly
There are 3 different ways to contact PIXEL SUPPORT.
Remember to check your email spam/junk folder for replies
Do NOT send multiple Pixel support tickets in quick succession...otherwise their spambot might eat them
1️⃣ You can contact Pixel support directly through your game settings menu
2️⃣ You can also contact Pixel support directly through this link
Do NOT type in the white search box....scroll down to the categories written in BLUE.
3️⃣ You can also send an email to Pixel Support directly through this email address
If you contact Pixel Support directly via the email address below....you MUST include your player ID number....which can be found in your game settings menu
