Definition
Indoor soccer, also known as indoor football, is a variant of association football (soccer) that is played within an enclosed arena. The playing surface is typically artificial turf or a hard surface, and the area is bounded by walls or dasher boards that may be used in play. The game features a reduced number of players per side, a smaller field of play, and modified rules compared to standard outdoor soccer.
History
The origins of indoor soccer trace back to the mid‑20th century in North America, where the sport emerged as a year‑round alternative to outdoor soccer in regions with harsh winter climates. Early organized indoor leagues appeared in the United States and Canada during the 1960s and 1970s. The format was subsequently adopted in other countries, leading to the development of distinct indoor soccer leagues and tournaments worldwide.
Rules and Gameplay

| Team size | Typically 5 to 7 field players plus a goalkeeper | 5 players total, including a goalkeeper |
| Ball | Size 5 ball, slightly less bounce than outdoor ball | Size 4 ball, low‑bounce, reduced pressure |
| Match duration | Two halves of 20–25 minutes, often with a running clock | Two halves of 20 minutes, stoppage time added |
| Substitutions | Unlimited “on‑the‑fly” substitutions | Unlimited “on‑the‑fly” substitutions |

Rule sets may vary between leagues, with some indoor soccer competitions employing hybrid rules that blend elements of traditional soccer, futsal, and ice‑hockey style play.

Popularity and Geographic Distribution
Indoor soccer enjoys considerable popularity in North America, particularly in the United States and Canada, where it serves as a recreational activity during colder months and as a competitive sport with semi‑professional leagues. In Europe, the indoor variant most widely recognized is futsal, which is played in countries such as Spain, Portugal, Brazil (though the latter is outside Europe), and the United Kingdom. South America, especially Brazil and Argentina, has a strong futsal culture that is often conflated with indoor soccer. The sport is also present in Asia and Oceania, primarily as a training tool for youth development and as a leisure activity.
