Although Brain Age: Nintendo Switch Training is a game that doesn’t support online play, there is one important feature in the game that requires a Nintendo Switch Online subscription.

Brain Age: Nintendo Switch Training allows players to email themselves reports of their brain’s age and other activity to their PC and smartphone.

In order to make use of this email report feature, you must have a Nintendo Switch Online subscription. It wouldn’t work without a subscription.
