What is the maximum number of free entries I can earn per day/week/month?

There is No maximum, however each member is limited to a Minimum of 45 Free Entries in a Calendar Month, with additional promotions for Birthdays, etc. It is possible to earn many more Free Entries by joining the V.I.P. version in the Avazoo App. This will open up many additional opportunities to earn a lot more Free Entries for V.I.P. members than members who stick with using the basic Free version of the app.
