Tennis polo
The sport is played on a grass field between 80 and 100 yards long and 50 to 65 yards wide. The goal area is a semicircular line with an 11-yard radius and the penalty mark at 13 yards from the goal. An experimental rule has a second semicircular line on the field with a 17-yard radius. Generally, a field for gridiron football or soccer can be used.
International rules football
The rules are designed to provide a compromise or combine between those of the two codes, with Gaelic football players being advantaged by the use of a round ball and a rectangular field measured about 160 yards long by 98 yards wide (Australian rules uses an oval ball and field), while the Australian rules football players benefit from the opportunity to tackle by grabbing between the shoulders and thighs and pulling to the ground, something banned in Gaelic football. The game also introduces the concept of the mark, from Australian rules football, with a free kick awarded for a ball caught from a kick of over 15 metres, where the kick must be in the forward direction if originating from a teammate.
A player must bounce, solo (kick into one's own hands) or touch the ball on the ground once every 10 metres or six steps. A maximum of two bounces per possession are allowed, while players can solo the ball as often as they wish on a possession. Unlike in Gaelic football, the ball may be lifted directly off the ground, without putting a foot underneath it first. Players however cannot scoop the ball off the ground to a team-mate, nor pick up the ball if they are on their knees or on the ground. If a foul is committed, a free kick will be awarded, though referees (called umpires in Australian Rules) can give the fouled player advantage to play on at their discretion.
The game uses two large posts usually sets 6.5 metres apart, and connected 2.5 metres above the ground by a crossbar with a goal net that could extend behind the goalposts and attached to the crossbar and lower goalposts, as in Gaelic football. A further 6.5 metres apart on either side of those and not connected by a crossbar are 2 small posts, known as behind posts, as in Australian rules football.
