Basketball
It is hard to think of something more in basketball online free games than throwing a ball into a basket. Sometimes, there are additions to the regular scheme ‘player-ball’. They can be: drawing auxiliary line, on which the ball will roll into the basket from its current position (the game ‘Dunk Line’ hardly knows the regular acts of throwing it); in ‘Finger Basketball’, it seems that baskets are not the main thing – most importantly it is to not allow it hit the floor and manage to tap while it is below the given line but over the floor. But yes, mostly, it is about the regular scheme mentioned upper and ability to unlock new balls and features.
