Add a stamp card feature (sandwich card mechanic) to coin packages to increase transactions per buyer


  • Slotomania’s new Stamp It feature gives players a chance to earn a free coin package, ‘Buy 4 coin packages to get 1 free’ (image 1).
  • A Stamp It card is visible from the coin store with more information about the feature (image 2).
  • Players receive a stamp for each purchase. The estimated free coin prize is taken from the average of four purchases (image 3).
  • Once a Stamp It card has been filled, players are notified with a dialogue displaying the amount of the free coin package. In this example, the free coin package was worth $1.64 (image 4).
