Double or nothing
Encyclopedia
Double or nothing in a betting situation is where the loser of a bet gets another chance at the bet. When a "double or nothing" bet is requested by the loser, if the winner accepts, then they play again. If the loser of the initial bet loses again, then the winner gets double the original bet. But if the loser of the initial bet wins, then he owes nothing. For example, if you owe someone $20 from a bet and you place a "double or nothing" bet with them and lose again, then you owe them $40; but if you win, then you owe them nothing. After the second bet, either the loser owes the winner DOUBLE the original bet OR NOTHING, hence the phrase. This is the dictionary definition of this phrase.

There is a variant to the above where the loser of the second bet pays the winner double the original bet regardless of who won the first bet. However, this is a less common usage of this phrase.

In a regular poker sit’n’go it is correct to play with the intention of accumulating 100% of the chips in the game, thereby placing 1st and securing for yourself the maximum possible prize money. In a double or nothing poker sit’n’go it is now no longer relevant if you finish the game with 100% of the chips or only 1% of the chips, as long as you are still in the game once 50% of the players have been eliminated. Because of this difference in prize structure, a double or nothing poker sit’n’go requires significantly different poker strategy than a regular poker sit'n'go.
