There are 4 ways to earn free diamonds, some easier than others:

  1. Earn up to 30 diamonds per achievement.
  2. Watch video ads in game bank (iOS & Android games only).
  3. Play puzzles and earn 5 diamonds.
  4. Catch morphs during events for 1 occasional diamond.

Watch Video Ad in Bank

Big Fish Games often offers diamonds in payment for watching a video ad. It’s an easy way to gain free diamonds! This feature is available for tablet games (iOS/Android/Kindle) only; it is not available for Windows PC games.

Your Coins & Diamonds

To find the ad, open the Bank — the blue plus sign at the top right of the screen, next to your coins and diamonds.

The Bank opens with various amounts of diamonds you can purchase. The video ad looks like a film reel icon with a diamond. If you don’t see this icon, try closing and re-opening the Bank. Tap the ad and wait for the video to complete before you close it. Close the Bank and you will receive your diamond(s). 

Bank & Diamonds

The numbers indicate how many times you can watch and collect diamonds, and how many diamonds you earn each time. In the example above, I can earn 1 diamond, 5 different times. Wait 10 minutes before viewing another ad. 

As of August 2020, the game began offering 10 diamonds at a time, 3 times per day. Each allotment is based on the game’s 24-hour clock. For more information, see Gifting Periods & Timers.
