a player is expected to keep track of the betting action. Losing track of the amount needed to call, called the bet to the player, happens occasionally, but multiple occurrences of this slow the game down and so it is discouraged. The dealer may be given the responsibility of tracking the current bet amount, from which each player has only to subtract their contribution, if any, thus far. To aid players in tracking bets, and to ensure all players have bet the correct amount, players stack the amount they have bet in the current round in front of them. When the betting round is over (a common phrase is "the pot's good"), the players will push their stacks into the pot or the dealer will gather them into the pot. Tossing chips directly into the pot (known as splashing the pot), though popular in film and television depictions of the game, causes confusion over the amount of a raise and can be used to hide the true amount of a bet. Likewise, string raises, or the act of raising by first placing chips to call and then adding chips to raise, causes confusion over the amount bet. Both actions are generally prohibited at casinos and discouraged at least in other cash games. Acting out of turn Most actions (calls, raises or folds) occurring out-of-turn—when players to the right of the player acting have not yet made decisions as to their own action—are considered improper, for several reasons. First, since actions by a player give information to other players, acting out of turn gives the person in turn information that they normally would not have, to the detriment of players who have already acted. For instance, say that with three players in a hand, Player A has a weak hand but decides to try a bluff with a large opening bet. Player C then folds out of turn while Player B is making up their mind. Player B now knows that if they fold, A will take the pot, and also knows that they cannot be re-raised if they call. This may encourage Player B, if they have a good "drawing hand" (a hand currently worth nothing but with a good chance to improve substantially in subsequent rounds), to call the bet, to the disadvantage of Player A. Second, calling or raising out of turn, in addition to the information it
