The game limit is a definition that is dependent on the financial aspect of the game you are involved in. There are two types of online poker games if we look at poker from the money point of view: there are the low-limit games and the high-limit games. The high-limit games are the games where lots of money are being played and bet. Low-limit games are on the other side, they are games with little money involved online sports betting.
Betting structures are based on limits imposed on each bet made in the game. Looking at this aspect we can distinguish four types of games:
1. The fixed-limit games
These games are sometimes named the structured limit games. Wherever there is such a game it means the players will only bet the amount that was set previously. Of course a bet is equal to the small blind and the big blind is double. For more information, when naming such a game, people use terms like $2/$4, $15/$30 games. This way the player who wants to enter the poker room knows from the start what he or she will be betting on. Lets say you are playing in a $2/$4 game. This means you will bet $2 at a time, this being the amount that will be placed as a bet on the flop and pre-flop, with the exception of the big blind of course. On the turn and on the river however the bets will double and each bet value will be $4. There is also a limit of batches per round. Every player is only allowed 4 bets per round. That means something like betting once, calling a re-rising, and being raised again.
Sometimes there are structured games that have three amounts in their name, like $2/$4/$8. The bets will be placed the same as described before, with the exception that when getting on the river, the bet gets doubled again, so from the initial $2 on the pre-flop and flop, it doubles on the turn to $4, and then it doubles again on the river for $8. But the players are not obliged to place that re-doubled bet on the river. They have an option here, they can either bet $4 or $8, whatever suites them the most.
2. The spread limit games
These are games that include the betting amount within an interval of values given by the name of the game. These game names will contain the numbers that limit the bets. For example in a $4-$8 game, players can place any bet as long as it is at least $4 and at the most $8. You can bet anything between $4 and $8 during any round.
We can find games that have four amounts in the name, like : $4-$8-$10-$12, this means that in the first two betting rounds, pre-flop and flop the player can bet between $4 and $8, on the third betting round, the turn, the player can bet anything between $4 and $10, and finally on the river the upper limit of the bets is increased to $12, so the bets can be anywhere from $4 to $12.
Although less encountered, there are games that have three amounts in their name, like: $4-$8-$10. This only means that until the river the batches are between $4 and $8, but once reaching the river the upper limit will increase and the batch can be placed using amounts from $4 to $10.
