WWE chest odds calculator
Explore the published reward pool for your Town Hall. These are approximate scenarios, not promised rewards or personalized odds.
What the calculation assumes
For a constant independent drop probability p across n chests, the chance of at least one selected reward is 1 − (1 − p)ⁿ. The expected count is n × p. An expected count is an average across repeated scenarios; it is not inventory you have earned.
Supercell lists Contract Chests as 9.10% in its headline rates and 9.09% in its detailed tables. The calculator preserves both as a small result range. Other rates are also rounded; the displayed pool totals may differ slightly from 100%. We do not silently normalize them.
Champ Medals are only available during Equipment Blast. This source does not explain redistribution before or after that event, so those Town Hall pools remain unavailable outside the published scenario. The calendar's conflicting September 8–9 start labels do not establish a precise activation time.
Ownership exclusions and individual skin chances are not specified in the captured tables. Hero Skin is an aggregate reward category, not an equal chance for each named skin. Personalized ownership adjustments remain unavailable. A Contract's 24-hour access period is separate from the global challenge deadline.
