Virtual Regatta Inshore gives you access to races, VR challenges, private races and Relax challenges, even if you don't have an account. However, an account is required to enter any of the "eSailing World Championship" challenges.
When you start Virtual Regatta for the first time, you receive a nickname automatically that looks like "Boat-XXXX".
As a guest, you have access to all the features of Virtual Regatta Inshore, you can change your game settings, earn barrels when you complete races, and have an ELO ranking.
Your guest player profile is tied to the device or browser you use to play. If you play from your mobile device for instance, you will not see your progress on your computer, and vice versa. This is why we recommend that you create an account: it will allow you to see your track record and credit balance on every device you play on.
Also, you can't change your nickname and personal info without creating an account.
