Flinger is a game played with rubber discs and is similar to boules.The aim of the game is to throw the large discs as close as possible tothe small target disc. The game can take place practically on any kind of surface and is not limited by space. The playing field is only defined for competitions. Flinger is usually played by two players or two pairs of players until one of them reaches 13 points. The game is played with 8 large rubber discs and one small target disc. In the beginning, every player is given 4 large discs. If pairs are playing, each player receives 2 large discs of the same colour. The right to start the game – by tossing first, is defined by lot. The player who scores at least one point after both of them have thrown all the discs tosses the small target disc. Each player throws one disc at a time and continues throwing discs until their disc gets the closest to the target. After that, it is the opponent's turn to toss discs following the same rule. When one of the players has run out of discs, the other one throws their remaining discs, unless they have already scored 13 points. When the players have no more discs, the discs that are closer than their opponent's to the target are counted, with each winning disc scoring 1 point.

The game has its origins in Istria, where many years ago it was played by herdsmen. Most often, they called it ‘škuljanje’. The game had simple rules and took place on a meadow where players would throw stones of different forms and weight to a target stone. In Slovenia, the tradition of ‘škuljanje’ has been well preserved at the Škulja Sport Society (ŠD Škulja). In the time of rubber and plastics, ‘škulje’ (stones) were replaced by rubber or plastic discs which were at first available only in Italy. In the course of time, this ‘holiday’ game with rubber discs has become known all around Slovenia. The first serious open tournaments with prizes, rules and reported results were played in 2005 in the Gorenjska region. Since the number of enthusiasts of the game quickly increased, the need to set up an umbrella organisation and to unify the rules arose. In view of this purpose, the first sport society which at the moment acts as a Flinger Organisation of Slovenia, was established on 2nd July 2008 in Češnjica pri Podnartu. The president of the society is Mr Igor Dornik, and the Slovenian name of the game ‘prstomet’ (flinger) was suggested by Mr Tomaž Travnik. The rules for competitions were set out by the members of the society.

Discs for competition are made of a special rubber mixture. The colours of the discs are red and blue, exceptionally also green and yellow. They have the form of undulatory discs with five linked rings and a hole in the middle. The outer diameter measures 100mm (+- 2mm), while the diameter of the hole measures 15mm (+- 1mm). A disc weighs approximately 75g; the tolerance depends on the accuracy of the producer. The small target disc can be yellow or green. It has a form of an undulatory disc with three linked rings and a hole in the middle. The outer diameter measures 65mm (+- 2mm), while the diameter of the hole measures 15mm (+- 1mm). The small disc weighs approximately 30g; the tolerance depends on the accuracy of the producer.

Competition surfaces must be uniform throughout all the lanes.  The lane must be at least 1.5m wide and 10m long. The boundary lines have to be marked along the court's entire length and width, with a max. 5cm wide strip, string, colour or chalk. On the outside of the starting point of each lane, there must be a marked area (Picture – mark: A) within which a player stands with at least one foot. This area must be as wide as a lane and 0.5m long. The lanes must be marked at 5 and 10m with the game being played within these areas. The playing field (all the lanes together) must be separated from the remaining area with a safety strip (Picture – mark: B). At the beginning of the lanes, the distance to the safety strip must be min 2.5m, at the end 2m, and on both sides min. 1m.
