Parimutuel betting (from the French: "Pari Mutuel" or mutual betting) is a betting system in which all bets of a particular type are placed together in a pool; taxes and the "house-take" or "vigorish" are removed, and payoff odds are calculated by sharing the pool among all winning bets.
 In some countries it is known as the Tote after the totalisator, which calculates and displays bets already made.
A betting pool, sports lottery, sweep, or office pool if done at work, is a form of gambling, specifically a variant of parimutuel betting influenced by lotteries, where gamblers pay a fixed price into a "pool" (from which taxes and a house "take" or "vig" are removed), and then make a selection on an outcome, usually related to sport.
 In an informal game, the vig is usually quite small or non-existent.
 The pool is evenly divided between those that have made the correct selection.
 There are no odds involved; each winner's payoff depends simply on the number of gamblers and the number of winners.
 (True parimutuel betting, which was historically referred to as pool betting, involves both odds calculations and variable wager amounts.)
