Four engine templates
Classic pay-lines, cascading tumbles with multipliers, all-ways pays, and cluster pays — each a locked, tested maths model you can retheme without touching the payout maths.

SlotBot turns one sentence into a complete, playable casino slot: hand-crafted-looking symbols, an animated mascot, bonus features, verified maths and a server-authoritative engine — generated end-to-end in about twenty minutes.
- Server-authoritative outcomes
- Exact rational maths
- RTP verified by simulation
- Export & self-host
How it works
From one line to a live game in five stages
Every build runs the same production pipeline. You watch it happen live — thumbnails land as they're generated, and the game is playable the moment verification passes.
-
01
Describe the theme
One sentence is enough. Pick an engine template, a bonus module, an art style and a mood — or let SlotBot suggest a brief for you.
-
02
Theme expansion
Gemini expands your idea into a full theme manifest: eleven symbol slots, palette, background, mascot personality, feature flavour and localisation strings.
-
03
Parallel asset generation
Symbols, backgrounds, reel frame and splash art are generated in parallel; the mascot is animated from reference frames with Veo or Seedance and chroma-keyed into a lightweight animated AVIF.
-
04
Assemble & verify
Assets are hashed and promoted into
game.yaml. Schema validation, immutable math-hash checks and a deterministic smoke simulation gate every build. -
05
Play, tweak, export
Spin it instantly in the studio, edit any layer — math, features, effects, cast, layout — then export a playable release or a container image.
What you get
Everything a real slot needs. Not a mock-up.
Pluggable bonus modules
Free Spins with retriggers, Hold & Win with locked prize coins and respins, Pick & Click with server-held prizes — plus ante bet, bonus buy and collectables.
Animated mascots & Spine rigs
An idle loop and a win celebration are generated as video, keyed and normalised into crisp animated AVIF. Optional Spine rigs give you a skeletal character you can pose and re-animate.
A maths lab, not a guess
Exact rational payouts, predictive RTP profiles, million-round Monte-Carlo simulation, hit-rate bands and release-evidence reports — all reproducible from a seed.
Built on a real engine
Server-authoritative from the first spin
SlotBot doesn't render a pretend slot in the browser. Every spin is resolved by a game host with a wallet, a round store and an ordered event stream — the client only presents what the server decided. That's the same architecture a regulated studio ships.
- Integer minor units and exact bigint rational arithmetic — no floating-point drift in payouts.
- Immutable math hash — a retheme must produce the identical hash, so art can never change odds.
- ~95 feature mechanics in the catalogue: wilds, scatters, multipliers, tumbles, respins, jackpots and more.
- Pseudo-localisation out of the box, with translated copy generated alongside the theme.
- Canvas-2D web client as a single custom element — no heavy game framework, plays on any device.

Generate first. Then take the wheel.
Every layer of a generated game is editable in the browser, and every edit is verified before it can be played.
Math model editor
Tune reel strips, paytables and feature weights; predict RTP instantly, then confirm with a full simulation.
Feature & effects layers
Swap bonus modules, add jackpots and collectables, and apply event-driven canvas effects — anticipation, big-win, tumbles.
Cast & media lab
Regenerate any symbol or background, re-animate the mascot, upload your own art, and manage the whole asset set with provenance.
UI layout & viewport
Portrait, landscape, immersive chrome, cabinet mode — layouts are templates, so a game fits every screen.
Live build progress
Streamed build events show each job's status, previews and retries as they happen. Pause for review, approve, resume.
Export & deploy
Download an assets pack, a self-contained playable release (node server.mjs), or a container image ready for any cloud.

FAQ
Questions, answered
Is the output actually playable, or just concept art?
Playable. Each build produces a compiled game bundle, generated assets, and a running game host. You can spin it in the studio immediately and export it as a standalone server.
Where do the images and animations come from?
Symbols, backgrounds and splash art are generated with Google's Gemini image models. Mascot animations are generated as short video clips (Veo or Seedance), then chroma-keyed and encoded to animated AVIF. Every asset records its provider, model and prompt.
How do I know the maths is right?
Payouts use exact rational arithmetic. Every build runs schema validation, a math-hash equality check and a deterministic smoke simulation; release builds require ten-million-round evidence within RTP and hit-rate bands.
Can I use my own art or tweak the design?
Yes — upload your own assets, regenerate individual pieces, or edit any layer (maths, features, effects, layout, cast) in the studio. Edits are re-verified before play.
Who can access the studio?
The studio at app.slotbot.dev is currently invite-only while we run private builds. If you have an access code, hit "Try it now".
