JUNE 5, 2026 – Netmarble, a leading developer and publisher of high-quality games, announced that its mobile idle RPG StoneAge Idle Adventure has launched a special pre-event celebrating the game's upcoming 100th day of service since launch.

Ahead of the game’s milestone, Netmarble is hosting a 100-Day Celebration Push Event through June 18. Players can earn up to 44,000 Blue Gems, one of the game’s core currencies, simply by logging in and claiming push rewards.

Netmarble has also prepared seven commemorative coupon codes packed with rewards. By entering coupon codes released through June 18, players can obtain 9,000 Blue Gems, 700 Pet Summon Tickets, 500 Capture Tickets and 500 Speed Up Tokens.

Meanwhile, a recent update introduced the new Rate Up Pet “Kingor.” A Water-type melee Pet, Kingor charges toward the farthest enemy within range, disrupting enemy formations and creating opportunities on the battlefield. As combat continues, Kingor recovers itself and gradually becomes more powerful.
