DAU / MAU

The count of unique players active in a single day (DAU) versus in a rolling or calendar month (MAU).

Definition

DAU and MAU are volume engagement metrics borrowed from consumer apps, counting distinct players who performed a qualifying action — login, wager, or deposit, depending on the definition — in the period. They describe the size of the active audience rather than its value, so they are always read alongside revenue metrics. The exact definition of 'active' matters and varies between operators, which makes cross-company comparison unreliable. The ratio of the two — DAU divided by MAU — is used as a stickiness measure.

Worked example

An operator with 25,000 players active on an average day and 250,000 active across the month has a DAU/MAU ratio of 0.10, meaning the typical monthly player visits on about 10% of days.

Why it matters

For a learner, it gives a plain-language sense of how many people use a product and how often. For a professional, these are useful engagement proxies but are definition-sensitive and value-blind, so they are never used alone.

Note: 'Active' has no industry-standard definition; whether it means login, wager or deposit differs by operator, so DAU/MAU figures are not directly comparable across companies.
