Sadly, you missed the wizard win.
Nintendo is offering a chance to try Splatoon 2 for those on the fence again.
A special Splatoon 2 demo is now available on the eShop, which will be live starting tomorrow at 10 a.m. and ending on Monday at 9:59 a.m (Eastern). All of the multiplayer functions will be included, and downloading the demo will trigger an email with a 7-day Switch Online free trial.
Progress from the demo will be carried into the final game, and during the demo period the game will be 20% off if purchased digitally.
