How the Odds Engine Works

Step 02

Set Your Token Budget

Use the slider or type directly to set how many tokens you plan to spend. The engine supports budgets from 0 to 100,000 tokens.

Step 03

Toggle Dupe Refund

Enable duplicate refund to factor in Blooket's sell-back mechanic. This uses a precomputed effective cost that lowers the price per box.

Step 04

Read Your Exact Odds

The calculator returns three real-time probabilities: Epic+, Legendary, and Chroma. These are exact — not averages, not simulations.

Step 05

Run Full Simulation (Optional)

For deep analysis, run a Monte Carlo simulation in a web worker. This runs thousands of iterations off the main thread.
