Puzzle Games

Our goal is to create games that everyone can enjoy and love playing for years! To achieve this, we extensively evaluate product-market fit throughout the whole game development process.

Powered by Cutting-Edge Technology

We build games with our AI enhanced Puzzle Engine technology, which enables us to efficiently experiment, create and release game prototypes, features and content.
