The game’s stamp collections, which are earned by playing the various slot titles on offer through Jackpot World, are one of the key features of the game. 

According to Jackpot World, the introduction of the Classic Bonus Stamp feature has resulted in a 10% increase in players participating in stamp exchange events. One of the key aspects of the new feature allows players to complete their collections, swapping out any existing stamps for the new Classic Bonus Stamp edition. 

Jackpot World Producer Emma Li commented: “Jackpot World's mission is to delight our players with an out-of-this-world experience when playing their beloved Stamp Collection. As an innovator in the mobile game space, we never stop exploring new ways to engage with our players and enhance the gaming experience.  

“From its inception, Jackpot World has been designed to spread fun around the world and with the brand-new Classic Bonus Stamp feature, we are enhancing the experience for players everywhere.” 

Jackpot World’s portfolio of slots titles, which include 777, Fortune Babies, Fortune Tree, Mighty Tiger and Penguin Quest, also offer a range of bonuses and free spin mechanisms.  

Although largely free-to-play, the game also offers in-play purchases, for players who desire to boost their coin levels or stamp collections. 

However, as it’s not a real-money gambling service, Jackpot World is not restricted by the regulations of most territories, and is available to play internationally.
