In floorball, the objective is to get a plastic whiffle ball into a net with the aid of the stick past a goaltender.

Field Players
Typical equipment for a floorball player consists of a pair of shorts, a shirt, socks and indoor sport shoes.  In addition to that, players are allowed to wear shin guards, eye protectors and protective padding for vital areas.  Players, except for the goalkeeper, also carry sticks.  A floorball player is also known as a 'floorballer'.

Sticks
A floorball stick is short compared with hockey; the maximum size for a stick is 105 cm.  As a stick cannot weigh any more than 350 grams, floorball manufacturers produce sticks that are often made of carbon and composite materials.

Goalkeepers
Goalkeepers wear protection that is very limited; padded pants, a padded chest protector, and a helmet.  The goalkeeper can also wear other protective equipment, but bulky padding is not permitted.  Some of this other protective equipment includes knee pads, jocks (for men), and gloves.

Ball
A floor ball weighs 23 grams with a diameter of 72 mm.  It has 26 holes in it; each of which are 11 mm in diameter.  Many of these balls now are made with aerodynamic technology, where the ball has over a thousand small dimples in it that reduce air resistance.  It looks like a whiffle ball.

Rules
Each team fields six players at a time on the court, one player being a goalkeeper.  A floorball game is played over two 25-minute halves with a continuous clock.  Time is stopped for injuries and stoppages in the final minute of the game.  Each team is allowed a timeout of 30 seconds. 

Checking is disallowed in floorball. Controlled shoulder-to-shoulder contact is allowed, but ice hockey-like checking is forbidden.  Pushing players without the ball or competing for a loose ball is also disallowed, and many of these infractions lead to two minute penalties.  The best comparison in terms of legal physical contact is soccer, where checking is used to improve one's positioning in relation to the ball rather than to remove an opposing player from the play.  In addition to checking, players cannot lift another opponents stick or perform any stick infractions in order to get to the ball.  As well, players may not raise their stick or play the ball above their knee level, and a stick cannot be placed in between an opponent's legs (to avoid tripping).  The rules of floorball are based on safety of the players.

When a player commits a foul, or when the ball is deemed unplayable, play is resumed from a free hit.  A free hit involves a player from one team to start play from the place where the ball was last deemed unplayable.  A comparison of this is a free kick in soccer.  For many fouls, such as stick infractions, a free hit is the only discipline provided.  However, at the referee's discretion, a penalty may be worth either two or five minutes.  At that point, the player who committed the foul sits in the penalty area, and his team is short handed for the time of the penalty.  If an 'extreme' foul is committed, such as physical contact or unsportsmanlike behavior, a player may receive a 10 minute penalty or even be removed from the game.
