02 / Studio
Named for the stone that cannot be missing.
A keystone is the wedge that locks an arch. Remove it and the span fails. We build that way: maths, engine, and feel as one load path.
01
Maths first
The board has to tell the truth. Features earn their place in the model, not on a mood board.
02
Stonecraft underneath
One in-house engine. Titles share a spine so the next game does not start from rubble.
03
Feel that holds
Mechanics that compound across a session — not a costume wrapped around a single bonus.
Engine
Stonecraft
Our in-house TypeScript and WebGL slot framework. Built for Stake Engine, written so a title can move from math model to live board without a second architecture.
