In a no-limit game, a player is allowed to bet or raise according to the following rules: Some NL games do not have a maximum buy-in (effectively, 'infinite' max buy-in), but all NL games have a minimum buy-in and blind sizes. Minimum buy-ins for a NL game are usually in the range of 10-40 times the big blind. The size of the numbers being used to desribe the game usually give the context: while it's conceivable that someone may someday host a NL game with small and big blind sizes of $100 and $300, it's highly unlikely, and people playing at that level undoubtedly know what they mean when they speak to each other about a 100/300 game. In some cases, players may describe a no-limit game using just one pair of those numbers, such as describing a 2/5 NL game (small and big blind sizes of $2 and $5), or a 100-300 NL game (min and max buy-ins of $100 and $300). No-limit games are usually described with four numbers: the small blind size, the big blind size, the minimum buy-in, and the maximum buy-in. No-limit is generally not used as a betting structure for a particular variant that does not have blinds. No-limit (often abbreviated to just NL) is a type of betting structure for a poker game where the size of all bets and raises in any given betting round is essentially unlimited.
