Nintendo has introduced a program called Game Trials that allows Nintendo Online Subscription members to try out Mario Tennis Aces for free.

Game Trials is a system where you effectively borrow a Nintendo-chosen game for a limited time, and all progress saved for if you buy it - at a discounted rate.

From August 7 to August 13, the first Game Trial game is Mario Tennis Aces. The trial grants full access to the game, which will then also be on sale at a 33% discount for those who like what they play and want to fully own it. The sale will last until August 30th.

How to Play for Free - Game Trial Access

To access the free trial, you'll need to be a Nintendo Switch Online member, which costs $3.99 a month or $19.99 a year. Once you are subscribed to the membership, you can access the Game Trial by creating a Nintendo Account and access the eShop, and going to the "Nintendo Switch Online" section - which will include a section for all available Game Trials.
