Origine = Belgique Roundnet (also known as Spikeball) is a ball game created in 1989 by Jeff Knurek, inspired primarily by concepts from volleyball.

If it's a 3v3 game then the team has 4 hits to return the ball to the net[6] After the serve, there are no boundaries of play.

Materials needed for roundnet include a trampoline-like net, and a small ball with a 12-inch circumference.

For 2v2 games, players line up in a square around the net with their partner to one side, and a member of the opposing team on the other.

To determine who serves first in the match, teams will participate in a game of rock paper scissors/ A coin flip or an odd/even call.

To account for harsh sunlight, wind, or any other condition outside of the game; players will rotate serving positions ninety degrees every five points.

If they catch, swing at and miss, or drop the tossed ball, it results in a service fault.

If the teams could not determine whether the ball hit the rim or a pocket, the play is replayed.

If the ball hits the net again, a double bounce is called, and a point is given to the assuming receiving team.

If the defensive player makes an attempt to play at the ball if they do not have possession, they lose the point.

Even if the player hit a "kill shot", they will lose the point if they touch the set before the ball makes contact with the ground.

As is common with similar games such as ping-pong, tennis, and volleyball, teams can only win by two points.

Some potential modifications include splitting the play field in half (thus simplifying the game), only using one hand, or something called "Takes two to fwango"[14] which forces players to hold hands greatly increasing the difficulty of the game.

[citation needed] Some more potential game modifications include: Many competitive teams and players master these four fundamental skills: serve, pass/dig/set, attack (spike), and the body block.

These skills are standard practice for high-level advanced, premier, or pro division players.

[22] The server stands behind the 7 foot serving line, in attempt to hit the ball onto the net.

The servers objective is to hit a clean serve that results in a bad touch or a possible "ace".

Players usually use a combination of wrist snap, arm swing and rotation to deliver certain types of attacks.

[13] Players are permitted to enter the NHZ to bump or set the ball, as long as they are not performing the final hit of their possession.

Playing with the NHZ is an official rule of the International Roundnet Federation, but it is ignored by most casual Spikeball players.

[20] A "God-block" is when a player uses any part of their body, for example their hand, to deflect the ball back onto the net in one touch usually resulting in a "kill", in this case it would be called a "God-hand".
