No-Limit, Pot-Limit and Fixed-Limit Poker

Betting limits: what they control

Betting limits are the rules that dictate how much players can bet or raise during a hand⁴. They are not about who can play or how much money you bring to the table. They are about the size of each individual bet and raise, and they shape everything else about the game: how fast the pot grows, how much bluffing costs, and how much of your stack you can put at risk on a single decision.

The three structures you will see in card rooms and online are:

• No-limit: you can bet any amount up to your total chips⁴
• Pot-limit: your bets can be up to the current size of the pot⁴
• Fixed-limit: you can only bet or raise by a predetermined amount⁴

Before going further, one practical point that applies to all three structures: verbal bets are binding. If you say "I bet $5" and then push out a different amount of chips, the dealer goes with the amount you said, not the chips¹. So knowing the limit structure matters before you open your mouth, because in a no-limit game a careless "I'm all in" is enforceable.

No-limit: bet any amount up to your stack

No-limit is the structure most people picture when they think of poker. The term refers to a betting structure where players are allowed to bet or raise any amount at any given time⁹. Texas Hold'em is often played as a no-limit game, which means it has no maximum bet⁶, and the popular form of the game is abbreviated NL Hold'em for exactly this reason¹⁰.

The rules are simple at both ends:

• The floor: the minimum bet is the size of the big blind. In no-limit Omaha, for example, the minimum bet is the same as the size of the big blind¹¹.
• The ceiling: there is none. Players can bet any amount they wish, including their entire stacks, as long as the minimum bet is placed². Betting everything is called moving all-in.

In Macau's official Texas Hold'em rules, on tables with no betting limit set, a player may bet all the chips they hold at the table, at or above the minimum bet⁵. The same rules note that on unlimited tables there is no limit on the bet or raise amount, and when only two players remain in a hand, the raise amount is unrestricted⁵. Omaha's official Macau rules carry the same all-in provision: nothing stops a player from putting all their remaining chips on one outcome¹².

A raise in no-limit must be at least equal to the previous bet or raise in that round⁵. So while you can bet any amount, you cannot make a token raise of one chip over a large bet; your raise has to match the last one in size at minimum.

No-limit Omaha exists too, though it is far less common than the pot-limit version. In No-Limit Omaha, betting has no limit and a player can go all-in at any time, removing the pot-limit betting structure that defines PLO³.

If you are new to the game itself rather than just the structure, the Texas Hold'em rules page covers the blinds and betting rounds that these limits sit on top of.

Pot-limit and fixed-limit: the other two structures

Pot-limit

In pot-limit, bets can be up to the current size of the pot⁴. It is a betting structure where the maximum allowed bet or raise is a pot-sized bet, and Omaha is the game commonly played this way⁹. The largest bet you can make is governed by the pot size in front of you², and you can never bet an amount higher than the pot¹⁰.

How do you calculate a pot-limit bet? The formula used in Pot-Limit Omaha is that the pot size is always equal to the money already in the pot, plus three times any outstanding bet¹³. That sounds odd until you unpack it: when you announce a pot-sized raise, you first call the outstanding bet, and the "pot" you are entitled to raise to includes that call plus the original pot. The three-times figure is the shortcut that produces the correct maximum. In practice, online games calculate it for you, and in live card rooms you can announce "pot" and the dealer will work out the figure.

Pot-Limit Omaha spreads its betting across four rounds: preflop, flop, turn and river¹³. If a player chooses to raise, the raise must be at least the amount of the previous bet or raise in that same round¹¹. The structure makes the betting more controlled than no-limit: you cannot shove a stack that dwarfs the pot on the first card, but the pots still grow quickly, because each pot-sized bet roughly triples what is already there.

Fixed-limit

Fixed-limit is the tightest of the three. Players can only bet or raise by a predetermined amount⁴, set by the game rules⁴. In Fixed Limit Texas Hold'em, your bets are limited to predefined sizes that the blinds dictate², and betting is restricted to a set amount each round¹⁴.

Macau's official Texas Hold'em rules spell out how the blind sizes drive the bets: in fixed-limit games, the first two rounds use the small blind amount and the last two rounds use the big blind amount⁵. So in a 10/20 fixed-limit game, you bet 10 on the first two streets and 20 on the last two, and nothing else.

The result is a game where bluffing is cheap relative to the pot, big hands get paid in small fixed installments, and you cannot lose your whole stack on one bad decision. 7 Card Stud is generally played as a fixed-limit game, meaning the maximum a player can bet is set by the house, with no going all-in⁷. Razz is the same: a fixed-limit game with five betting rounds, and no community cards or betting all-ins like in Hold'em⁸.

The cap: maximum raises per betting round

The cap is the maximum number of raises a player is allowed to make in a betting round, usually three or four¹⁵. It exists to stop two players from raising each other into infinity in a fixed-limit game, where every raise is the same small size and neither side ever has to commit much to keep going.

The cap sits on top of the betting structure, not instead of it:

• In fixed-limit games, Macau's official rules for both Texas Hold'em and Omaha set a maximum of three raises per betting round⁵. Fixed-limit Omaha allows a pot to be raised a maximum of three times per betting round, with the bet or raise equal to the size of the blinds¹¹. Liêng, a Vietnamese three-card game, uses the same idea in its fixed-limit form: a maximum of three to four raises per round, with bets only in predetermined amounts¹⁷.
• In no-limit games, raises are unlimited¹². Because each raise must be at least as big as the last, the action resolves itself: one player eventually bets enough that the other must commit a serious portion of their stack or fold.
• Heads-up is different again: when only two players remain, the raise amount is unrestricted even in limit games¹².

Note that the cap counts raises, not the opening bet. The first bet in a round is a bet, not a raise, so the cap limits how many raises can follow it.

There is a second, unrelated use of "cap" you may run into online: a cap game is one where there is a limit placed on the maximum amount of chips that can be wagered postflop⁹. That is a table rule about total wagered chips, not the raise count, and it appears mostly in high-stakes no-limit games where operators want to bound the risk.

How the cap works in practice

Here is a typical fixed-limit round with a three-raise cap:

1. Player A bets the fixed amount, say 10. This is a bet, not a raise.
2. Player B raises to 20. Raise one.
3. Player C raises to 30. Raise two.
4. Player A raises to 40. Raise three. The cap is reached.
5. From here, players may only call or fold for the rest of the round. Betting reopens with the next card.

If only two players are left in the hand, the cap is lifted in many rule sets and they can keep raising¹².

The cap also shows up in house-banked poker games, though in a different form. In Macau's progressive jackpot poker rules, a raise must be exactly double the ante bet, no more and no less, and if the player chooses not to raise, the spot is treated as a loss and the dealer takes the cards and the ante¹⁸. The raise payouts are capped by the house: four of a kind pays 1 to 20 and a straight flush pays 1 to 50, but neither may exceed the house's pre-set maximum per round¹⁸. These are casino table games against the house rather than player-versus-player poker, but they show the same principle: fixed amounts, fixed raises, and a ceiling on what any single round can cost or pay. You can read more about that family of games in casino poker games against the house.

One more practical note for live play: since verbal statements are binding and the dealer goes with the amount you say rather than the chips you place¹, announce your bets clearly. In a capped round, saying "raise" when you meant to call can commit you to the last legal raise.

Which limit structure suits which game

Each major poker variant has settled on a structure that fits how it plays:

The reasons are mostly historical and practical. Hold'em has only four betting rounds, so no-limit betting gives strong hands room to build big pots. Omaha deals four hole cards, which makes hands run close together in value; pot-limit keeps the gambling controlled while still allowing large pots. Stud games have five betting rounds, which would make no-limit play extremely swingy, so fixed amounts with a cap keep the game orderly.

Pot-Limit Omaha cash games run at stakes such as 50/50 blinds¹⁹, and no-limit Hold'em cash games run at blinds such as 50/100/200 and 100/200 with maximum buy-ins of 100,000¹⁹. The structure names appear in the game labels themselves: NLHE for no-limit Hold'em, PLO for pot-limit Omaha, and FL or just "limit" for fixed-limit games. "Limit" on its own describes a poker game with a fixed-limit structure, where betting and raising are in fixed amounts¹⁵.

If you are weighing which format to try first, the cash games vs tournaments page explains how chips and buy-ins differ, which interacts directly with how much the betting structure can hurt you.

Where the three structures appear in Asia

Across Asia's live and online poker scenes, the same three structures appear everywhere, attached to the same games:

• Macau casino poker rooms run Texas Hold'em under official rules that cover both no-limit and fixed-limit tables, with the fixed-limit version betting the small blind in the first two rounds and the big blind in the last two, and a three-raise cap per round⁵. Omaha tables in Macau follow the same cap, with all-in allowed in unlimited games¹².
• The Philippines has a large licensed poker room sector, with operators holding PAGCOR gaming licenses to run poker rooms²⁰, and the games spread are overwhelmingly no-limit Hold'em and pot-limit Omaha, matching the global standard.
• Vietnam has its own fixed-limit tradition through Liêng, a three-card game that comes in both fixed-limit and no-limit forms¹⁷.
• Online poker serving Asian players lists all three structures side by side. Japanese-language Hold'em pages describe the game as no-limit²¹, and Omaha pages describe it as mainly pot-limit²¹. No-Limit Omaha exists online as a niche alternative that strips out PLO's pot-limit structure³.
• House-banked poker tables in Asian casinos, such as progressive jackpot poker in Macau, use fixed amounts and fixed raise rules rather than any player-chosen bet sizes¹⁸.

For a first visit to a card room, the practical takeaway is this: check the structure before you sit down, because it is usually written in the game name. NL or no-limit means your whole stack is always at risk. PL or pot-limit means the pot sets your ceiling. FL, limit, or a game with fixed bet sizes means your per-round exposure is bounded, and the cap of three or four raises closes each round quickly.
