Detection, versions, stakes, and what happens when the table turns.
What exactly is the DonutSMP rig mod?
A Fabric client mod that controls gambling outcomes on Donut SMP. It hooks the client render path for blackjack, the paper game, coinflips, dice, slots and roulette, then applies your configured odds before the result is drawn. Nothing leaves your machine. It is a client-side rigging mod — no proxy, no second account, no server component.
Does it work on Donut SMP blackjack?
Yes. The mod reads the dealer hand from client-side entity state and reorders the draw to match your win rate. You can set a hard natural rate, a dealer-bust rate, and a bust guard that keeps you at or under 21.
Can the rig mod be detected?
The mod does not modify outgoing packets and writes nothing to chat. Server-side anti-cheat compares what the server sent against what the client reports — both are identical here. What changes is only what your client renders.
Which versions are supported?
Fabric 1.20.1 through 1.21.4, and Quilt on the same range. Forge is not supported. The installer picks the right build from your loader version.
How does the paper game rig work?
The paper game resolves a rarity tier before the reveal animation. The mod preselects the tier and holds it through the full cycle, so the animation is honest and the result is yours.
Is it free?
Yes. No account, no licence server, no payment, no telemetry. 240 KB jar.
Will my account get banned?
Run sane odds. The mod is invisible at the network layer, and the only signal left is win rate. A 65–80% profile looks like a good night; 100% at every table looks like a pattern.
Does it work on other servers?
It is tuned for Donut SMP's gambling plugins. Any server that resolves wagers client-side is readable, but the presets and the paper game logic are built around Donut SMP.
Where do I report a crash?
Check that you are on Fabric, not Forge or a modded launcher profile, then confirm the jar hash on the download page. Version mismatches are the cause of almost every crash report.
