Fastclick is a new optional feature in seterra that you can activate by putting "?fastclick=1" after the quiz url (for example, "https://online.seterra.com/en/vgp/3007?fastclick=1" is the link for the Europe: countries quiz with fastclick turned on). What this changes is that the game recognizes that the player has clicked a country when the click button is pressed, as opposed to when the click button is released (which is how it works without fastclick). Using this parameter is not only allowed on the leaderboards but also recommended by most top runners, as saving the time between clicking and releasing in every element ultimately allows for a reasonable timesave overall.

I'm pretty sure it falls under website since you still have to move your cursor from a country to another, but I can't confirm that because I'm not a mod.
