Squarelets
To mark World Blood Cancer Day in 2026, we were very excited to share that DKMS teamed up with Chaos Cookie to create a special edition of their flagship cosy mobile puzzle game, Squarelets.
Chaos Cookie is an independent, UK-based game studio dedicated to designing and developing engaging and mindful digital experiences – offering moments of calm, creativity, and connection through play.
The special DKMS partnership edition of Squarelets followed The Adventures of Little Red Blood Cell and guided players through the process of joining the stem cell register, while highlighting its importance.
The Adventures of the Little Red Blood Cell
This creative, medical-themed twist on the classic Little Red Riding Hood challenged players to complete special puzzle levels to progress through the story, raising awareness for blood cancer and the registration process.
The DKMS charity bundle
Alongside the free narrative event, Chaos Cookie also launching an exclusive DKMS Charity Bundle priced at £2.99. The bundle included five unique in-game hero skins inspired by real DKMS merchandise, as well as a superhero cape and cotton swab accessory.
Chaos Cookie generously committed 50% of developer net proceeds from every bundle sold directly to DKMS UK, which went directly towards the £40 cost of processing and registering a new potential blood stem cell donor.
“I love spending the day solving complex puzzles and building connections, but nothing is more impactful than the biological match that DKMS work to find every day. Chaos Cookie is proud to support DKMS because we believe that when we apply the right logic and a dedicated community to a global health challenge, we can literally change the impact for people everywhere.”
We are incredibly grateful to Beatka and the team at Chaos Cookie for finding such a creative way to bring our mission to the gaming community.

A huge thank you again to Beatka and the whole team at Chaos Chookie for your creativity, passion, and commitment to supporting our cause. And to every single person who downloaded the game, played the charity levels and helped spread awareness.
Partnerships like these show that life-saving awareness can happen anywhere, even through a mobile game.
