Skill
Those games online are for mastering some skills. Or showing them. They also develop particular skill you have to demonstrate and can be: shooting an aim, typing fast (and with a little mistakes, certainly), figuring out puzzles and jigsaws, throwing a ball into a basket (with different obstacles and level of toughness), playing billiard for free, jumping, building, trying to go through a space tunnel (this one is very tricky, we have to say), killing monsters from bazooka, assembling a constructor, drifting, collecting items for speed, trying to run away from other players and more.
