What reviewers look at.

Engine games are reviewed by people before they are published. Passing the automated maths and compliance checks is not enough on its own: the review decides whether a game goes live.

In our experience, presentation carries most of the weight. Reviewers respond to consistent art, animation that feels finished, and features that give players a reason to keep spinning. Generic or mismatched visuals are the fastest way to a low score.

In our own submissions, each game received three separate reviewer scores, and publication depended on the combined score clearing a threshold. A score can arrive without detailed notes, so we prepare the case for a game before it is submitted, not after.

Our guide How Engine review works covers the scoring, a pre-submission checklist and what to do after a low score.

What we deliver.

• Slot art and animation. A symbol set, backgrounds, UI and title art, animated in Spine, designed to hold up at review. See slot game art.
• A web-sdk frontend. The game client built on the Engine web-sdk with PixiJS and Svelte, responsive for mobile and desktop. See slot game development.
• A math-sdk model and RTP lock. The model built in the Engine math-sdk pipeline, simulated, reconciled and checked against the platform rules. See slot math and RTP.
• A review-ready package. The upload, the game description Engine asks for, and a short written quality case that explains the game to the reviewers.

You can hire us for the whole game or for the part you are missing, for example art for a game whose maths you already have.

How it works.

1. Concept check. We look at the theme, mechanic and target section of the lobby, and flag anything likely to fail review, such as themes that could appeal to under-18s.
2. Maths and greybox. A working model in the math-sdk and a playable greybox on the web-sdk.
3. Art, animation and frontend. Production of the final game, reviewed in playable builds.
4. Packaging and submission support. The upload, the description and the quality case, ready for you to submit under your publisher account.

Where a game lands in the lobby matters as much as how it scores. Publishers who have shared their results report that a game in a smaller, less crowded section can hold players far longer than a similar game in the main slot catalogue, where many new titles arrive every day. We plan the concept with its likely section in mind.

The economics, plainly.

Stake describes the commercial model on its own Engine page as a 10% GGR revenue share on approved games: publishers earn 10% of the gross gaming revenue their games generate. Stake also lists Engine games as exclusive to Stake, and in September 2026 it announced distribution to other operators.

That is the trade for not needing your own licence, legal entity or per-game certification. Engine games are listed as exclusive to Stake, so check the current publisher agreement for ownership, exclusivity and revenue terms before you submit, and plan your portfolio around what that agreement allows.

Our position.

Arcabo Games is an independent studio, not affiliated with Stake or Easygo. We build games for Engine ourselves, which is where our view of the review comes from, and we help other publishers do the same.
