HeatCheck Gaming's Unicorn Derby Awarded Maximum 3-Star Quality Ranking Ahead of Launch on Stake

TORONTO, ON, June 24, 2026 -- Boba Mint Holdings Inc. ("TNJ" or the "Company") is pleased to announce that Unicorn Derby, the first game developed by its HeatCheck Gaming division, has been awarded a 3-Star Quality Ranking by the Stake Engine review team, the highest ranking available on the platform.

All games approved for publication on Stake Engine receive a Quality Ranking ranging from 0 to 3 stars, with 3 stars representing the highest possible designation. According to Stake Engine guidelines, a 3-Star ranking is awarded only to studio-quality games demonstrating exceptional creativity, uniqueness and attention to detail. Games receiving a 3-Star ranking are eligible for optimal positioning throughout the Stake casino and inclusion in the featured New Releases section.

Unicorn Derby is a fantasy-themed slot game set in a magical kingdom where players can trigger exciting unicorn races that award multipliers across the game board. Featuring unique racing mechanics, multiple bonus modes and colorful fantasy visuals, the game is designed to deliver a fun and highly entertaining player experience.

"It's extremely rewarding to have the quality of Unicorn Derby validated by the Stake Engine review team, who are known for maintaining exceptionally high standards," said Andrew Shore, Chief Executive Officer of Boba Mint Holdings. "We believed we had built a great game, and receiving the highest possible rating reinforces that belief. To receive this level of recognition on our very first release is a significant achievement for the company and places HeatCheck alongside some of the industry's leading game studios. We view this as an exciting start for our casino gaming division and look forward to building on this momentum with future releases."

The Company believes the 3-Star designation provides strong validation of HeatCheck's game development capabilities and establishes a solid foundation for its growing portfolio of casino titles. HeatCheck intends to continue developing premium casino games exclusively for Stake while focusing on unique concepts, innovative mechanics and high production quality.

The achievement marks an important milestone for HeatCheck Gaming as it continues executing its strategy of building world-class casino games for one of the world's largest online casino platforms. With Unicorn Derby expected to launch shortly, the Company looks forward to expanding its presence within the rapidly growing Stake Engine ecosystem.
