Only public tool settings are included.

Case EV comparison

Compare the published price and expected item value before opening. A higher RTP does not mean a likely win; it is a long-run average across the displayed odds.

How expected value is calculated

Expected value adds each final item's value multiplied by its published drop chance, including nested-case outcomes. RTP is expected value divided by case price.

An average, not a prediction

An average does not predict your next opening. Repeated openings do not guarantee the expected return, and displayed values can change.
