DoDo validator

Applicable only for devices having access to Google Play Store.



Validator is not a runnable application therefore it is not listed as an application to start, however it appears in the list of installable applications provided by Android Settings.



Just restart DoDo (the main application) to validate your purchase. That makes the application ad-free therefore henceforth you will need to be online only for accessing global tables.



Installation of Validator preserves saved games, settings, statistics, scoreboards and achievements.
