Slot studio

The stone that locks the arch.

Keystone Studios builds HTML5 slots that hold under pressure. Every title sits on Stonecraft, our in-house engine — the piece the rest of the game leans on.

A second title is in the yard. It ships when it locks.

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.

  1. 01

    Maths first

    The board has to tell the truth. Features earn their place in the model, not on a mood board.

  2. 02

    Stonecraft underneath

    One in-house engine. Titles share a spine so the next game does not start from rubble.

  3. 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.
