Futsal is a football-based game played on a hardcourt like a basketball court, smaller than a football pitch, and mainly indoors. It has similarities to five-a-side football and indoor football.

Five-a-side football is a version of minifootball, in which each team fields five players. Other differences from association football include a smaller pitch, smaller goals, and a reduced game duration. Matches are played indoors, or outdoors on artificial grass pitches that may be enclosed within a barrier or "cage" to prevent the ball from leaving the playing area and keep the game constantly flowing.
