Design Your Own Draw Environment
Whether you need a loot box simulator, event raffle, or team assignment tool β just enter item names and assign probabilities. The tool validates that all probabilities sum to exactly 100% before running, preventing setup mistakes. Run between 1 and 1,000 trials to compare your theoretical odds against actual draw frequency in a live statistics table.
Frequently Asked Questions
Can I use decimal probabilities like 0.5%?
Yes. Decimal values are supported as long as all items sum to exactly 100%.
Will 100 trials always match my set odds exactly?
No β it is random, so results converge toward the set odds over many trials but will vary each run.
What if I leave an item name blank?
Blank names auto-fill as "Item N". Only items with a valid probability value are included in the draw.
