Update: played for years and stopped. Now noticing ads on top of ads. An ad may randomly play, then suddenly after video ends, you return to the app to find "watch video to unlock this card". Ridiculous! Ad revenue keeps apps afloat, however it does not TAKE OVER where there is more AD PLAY than GAMEPLAY available. Ads are 2-1 gamplay ratio here! Ap is dishonest about prize restocking. Prize section will look different per user. Was tested. When you near a prize..it will change to out of stock.
