Independent spirit.
Island roots.
Games, tools and training.
Built here in Puerto Rico.
Carved Stone Interactive is an independent game and software studio based in Puerto Rico. Its work spans entertainment, cybersecurity training and practical tools for people and businesses.
From Coquí Pop to GoToShoppersPR, Mi Nomina and HADES, each project is developed and maintained with its own audience in mind.
01 / Character
Made for its audience.
A game, a payroll application and a training lab serve different needs. Their design and language should reflect that.
02 / Curiosity
A clear purpose.
Find the next match, review employee hours or practice an investigation. Each project should make its core task clear.
03 / Care
Keep making it better.
We revisit our work, refine the details and bring our projects to new screens.
