Netmarble is launching a collaboration promotion between its mobile idle RPG 'Stone Age Idle' and Google Play.

Running until May 31, players can participate by purchasing Google Play gift cards at GS25 stores nationwide and registering through the 'Our Neighborhood GS' app. Stamps are earned upon logging into the app and accumulating GS ALL POINT rewards; payments made via GS PAY will receive stamps automatically. For cash or credit card payments, stamps can be earned by scanning a QR code or entering a mobile phone number.

Depending on the purchase amount of the Google Play gift card, players can receive essential in-game items for Stone Age Idle, such as Blue Gems, capture tickets, and pet summon vouchers, limited to one redemption per account.

Stamps collected during the event can also be used to enter a draw for prizes, including a 500,000 KRW Google Play gift card. In-game items and prizes will be distributed in bulk after the event concludes, and the event may end early if the budget is exhausted.
