Lua scripts
Free Lua dice bot scripts
11 betting systems written as dice bot scripts, each with the full source, a step-by-step explanation and the streak math for its default settings. Every script sets chance and nextbet and defines a dobet() function that runs after each roll, the same shape DiceBot scripts use.
You can run any of them for free in the DiceSim simulator, which rolls provably-fair dice in your browser. Nothing is wagered and you don’t need an account.
The scripts use the global names from Seuntjie’s DiceBot (chance, bethigh, nextbet, previousbet, balance, win), so they read the same in bots built on that API. They also read their settings from params, which only DiceSim provides: replace params.name or value with the value before pasting a script into another bot.

How to use a script
- Open a script and press Run it in the simulator. The script loads into the editor with the template’s starting balance.
- Set the starting balance and seeds in the config panel and the number of rolls in the control bar, then start the run. You can edit the code too; the draft is kept in this browser.
- Read the balance chart, and open the Bets tab to check individual bets. The Stress Test tab runs the same script on five different seed pairs at once.
- Try other values for the
paramssettings with the Auto-Tuner, and compare the risk numbers with the dice calculator. - Every global the scripts use is documented in the Lua reference.
