One-wall handball, also known as 1-wall, wallball or international fronton, is a wall game (indirect style) where the player hits a small rubber ball with their hand against a wall. The goal of the game is to score more points than the opponent. The player then hits the ball, and the ball bounces off the wall and the floor within court lines, if the opponent fails to return the ball, the player scores a point. The sport was created to bring together varieties, such as American handball, Basque pelota, Patball, Gaelic handball, Pêl-Law (Welsh handball) and Valencian frontó.

Courtfield

International fronton uses the most basic courtfield layout of the indirect style: one wall where the ball must bounce.

This only wall, the fronton, is wide and high. From the left and right corners two lines are drawn on the ground, long, that mark the place into which the ball may bounce, this is the courtfield.

There must be some free space out the courtfield for the players to play balls that are risking to bounce twice.

At from the fronton wall there is a line on the ground, the fault line. The serving player must throw the ball before that line, and the ball must surpass it after bouncing on the fronton.

At from the fronton there is another line on the ground, the back line, which the ball may not bounce from.

In agreement with American handball (and unlike Basque pelota and Valencian frontó) there is no left or back wall, the ball may bounce on the lines, and, specially, there is no line on the fronton for the ball to ball over.

Ball

The One Wall ball / International fronton ball ('big ball') is a synthetic one, without any default colour. According to the GAA Handball 1-Wall playing rules (as of January 2019, which is in line with United States Handball Association playing rules), the ball used shall be in line with the following: The material should be rubber or synthetic material. Colour is optional. Size is 1 and 7/8-inch diameter, with a variation of 1/32-inch, +/-. The ball shall be 61 grams, with a variation of 3 grams, +/-y Rebound from free fall, 70-inch drop to a hardwood floor is 48 to 52 inches at a temperature of 68 degrees F.

This ball is also used in the 'Big Ball' grades at the World Handball Championships organised by the World Handball Council. The one-wall ball is widely available - manufacturers of the one-all ball include O'Neills, Decathlon 'Urball' brand, MacSports 'Challenger' brand & Sky Bounce. The 'small ball' (mainly used in 4-Wall American handball/Gaelic handball competitions) is also used in the 'small ball' one-wall/wallball grades at the World Championships.

Rules Two players (1 against 1) or four players (2 against 2) play to score points until one of them attain two sets (composed by 21 points).

In case of a tie, 1–1 sets, a third set is played, where the first service is done by the winner of the previous set.

Players strike the ball with the hand so that it bounces on the fronton and falls into the courtfield. Whoever fails to do so commits a fault and so loses a point, then the opponent serves.

A fault is committed if: The player hits the ball with any other part of the body but the hand. The ball does not bounce on the fronton. The ball's first bounce on the ground is out the courtfield. The player strikes the ball after a second bounce on the ground.
