Definition of Double or Nothing
The expression could be translated as "Either you double or you get nothing". This is the philosophy of these sit'n'gos (since yes, this variant, often identified as DoN, is almost exclusively played in sit'n'go). The principle is simple. It is a sit'n'go which will often have 10 players. There will be sit'n'gos as much at 1 euro as at 1000 euros. Once the sit'n'go is launched, we will play until there are only 5 players left, which is half of the entries. All the eliminated players will win nothing and the 5 remaining players will double their investment.
The Double or Nothing sit'n'gos strategy
Unlike other types of tournaments or sit'n'gos that have an accumulation logic, Double or Nothing sit'n'gos will have a chip preservation logic, which will result in you playing conservatively. The majority of players in these games are very tight (which could be a counter-argument to encourage you to play aggressively). You'll never hit big jackpots quickly in these sit'n'gos, but for beginners who would like to learn the basics of poker, this could be a good school for them.
