Niu Niu Rules

What Niu Niu is and where it is played

Niu Niu, which you will also see written as Bull Bull, is a card game that splits your five cards into a three-card hand and a two-card hand, then compares them against the dealer's. It is popular in southeastern China and Cambodia, and the casino version at Hoiana in Vietnam is a variant of that traditional game³. The name comes from the Chinese word for ox or bull, and the "niu" hands that give the game its structure are named after it.

In practice you will meet Niu Niu in three settings. It is a home and social game played for small stakes across the region. It is a casino table game: Hoiana in Vietnam spreads it under the name Hoiana Niu Niu, and City of Dreams Manila has offered a version called Super Niu Niu⁴. And it is a live-dealer game streamed from studios, where the same rules play out on your phone or laptop. Okada Manila also runs Super Niu Niu Plus, a side-bet version where you wager on other players' three-card hands or the dealer's, with side bets from PHP 100 and payouts up to 150 times².

Niu Niu belongs to the same family of nine-point card games as Pok Deng in Thailand, Bai Buu in southern Vietnam and Oicho-Kabu in Japan: all of them count card values toward a target and compare hands against a dealer rather than against each other. You can read more about that family in our guide to nine-point card games.

How a round is dealt and the objective

The game uses a single deck of 52 cards, and five cards are dealt to each player and the dealer each round¹. Once you look at your cards, your job is to set them into a three-card hand and a two-card hand. The objective is simple: end up with a higher-ranking hand than the dealer after you have arranged your cards¹.

The three-card hand is the foundation. If you can make three of your five cards total 10, 20 or 30, you have a valid Niu hand, and the remaining two cards determine how strong it is. If you cannot, you have a No Hand, and the round is decided by your single highest card instead.

In the casino version, you must place a wager on the "Even" area to take part, and you then have the option to add wagers on the "Double" and/or "Super Niu" areas¹. Settlement is made box by box, starting from the dealer's right-hand side and working left, and losses on the Double and Super Niu wagers may be taken from the insurance amount you placed in the reserve area⁴.

How the cards count

The point values are easy to remember. Kings, Queens and Jacks each count as 10, an Ace counts as 1, and every other card counts at its face value¹. So a 7 is worth 7, a 3 is worth 3, and a Queen is worth 10.

This is the same counting convention used across the nine-point family. In Hoiana Niu Niu, K, Q and J each count as 10, an Ace counts as 1, and every other card counts at its face value⁵. The three cards do not need any particular total beyond 10, 20 or 30 to qualify; the ranking from 20/10 at the top down to 11 at the bottom applies to the two-card remainder⁵.

For ranking single cards, the order is K, then Q, J, 10, 9, 8, 7, 6, 5, 4, 3, 2 and finally A¹. This matters for tiebreakers, which we cover below.

What makes a valid hand

A valid Niu hand needs three of your five cards to total exactly 10, 20 or 30¹. The remaining two cards then decide the strength of the hand, and their total gives the hand its name:

• Niu 1: the two remaining cards total 11¹
• Niu 2: the two remaining cards total 2 or 12¹
• Niu 3: the two remaining cards total 3 or 13¹
• Niu 4: the two remaining cards total 4 or 14¹
• Niu 5: the two remaining cards total 5 or 15⁶
• Niu 6: the two remaining cards total 6 or 16¹
• Niu 7: the two remaining cards total 7 or 17⁶
• Niu 8: the two remaining cards total 8 or 18⁶
• Niu 9: the two remaining cards total 9 or 19⁶
• Niu Niu: the two remaining cards total 10 or 20, so both halves of your hand end in zero¹

A worked example: you hold 7, 8, 5, King and 4. The 7, 8 and King total 25, which does not work. But 7, 8 and 5 total 20, which is valid, and the King and 4 left over total 14, making your hand Niu 4. If instead your leftover cards were a King and a Queen, they would total 20 and you would have Niu Niu, one of the strongest hands in the game.

If neither you nor the dealer can form three cards totaling 10, 20 or 30, the round is a No Hand for both sides, and the highest single card among your five decides it¹.

Hand rankings from Hoiana Niu Niu down to No Hand

The full ranking from the Hoiana rules, top to bottom¹:

1. Hoiana Niu Niu: four of a kind, four identical cards. This is the premium hand and the only one that does not need a three-card total of 10, 20 or 30⁸
2. Ultimate Niu Niu: all five cards are J, Q or K¹
3. Niu Niu: three cards totaling a multiple of 10, other two cards totaling 10 or 20¹
4. Niu 9 down through Niu 8, Niu 7, Niu 6, Niu 5, Niu 4, Niu 3, Niu 2, Niu 1, in that order¹
5. No Hand: no three cards total 10, 20 or 30¹

The two-card totals rank in the order 20/10, then 19/9, 18/8, 17/7, 16/6, 15/5, 14/4, 13/3, 12/2 and finally 11¹. That is why Niu 9 (leftover total of 9 or 19) beats Niu 4 (leftover total of 4 or 14): the higher the two-card total, the better the hand, with 10 or 20 at the top.

Note that the two special hands sit above everything. A hand of four matching cards, or five picture cards, outranks even a Niu Niu, and both pay the biggest multiples on the side bets.

Tiebreakers: highest card, then suit

Ties are common because two-card totals collide often, and the rules resolve them in two steps.

If your card total equals the dealer's, the highest ranked single card decides the winner. If the highest ranked card is also the same, the suit of that highest card decides it¹. The suit order is spades, then hearts, then clubs, then diamonds⁷.

So if both you and the dealer have Niu 6, and your highest card is a King while the dealer's is a Jack, you win. If you both hold a King as your high card, the spade beats the heart, the heart beats the club and the club beats the diamond.

The same logic applies to No Hand rounds: when neither side can form a valid three-card hand, the highest single card of the five is compared first, and the suit of that card breaks any remaining tie⁷. In the home version described by Ha Tien Vegas, if both players have Niu Niu, the higher two-card hand wins, then the higher single card within it, then the suit⁹.

The three bets: Even, Double and Super Niu

The casino game runs on three betting areas, and the structure is what makes it different from the home game¹:

• Even is the required bet. You must place a wager here to participate in the round⁸. It pays even money when you beat the dealer.
• Double is optional. It pays according to your hand strength, from even money on weak hands up to 3 to 1 on the top hands.
• Super Niu is optional and pays the biggest multiples, from even money up to 12 to 1.

The Double and Super Niu wagers can each be equal to or less than the Even wager, but never more¹. So if you bet 100 on Even, your Double and Super Niu bets can be anywhere from nothing up to 100 each.

The catch, and the thing every first-time player should understand before sitting down, is that the Double and Super Niu bets are not settled with just the chips you put on them. If you lose the round, the dealer may draw on an insurance amount you must place in a reserve area, which is why your maximum possible loss is much larger than your visible stake. That system is covered in the next two sections.

The reserve: the money you must set aside

If you bet on Double, you must place an insurance amount equal to twice that wager in the reserve area of the layout. If you bet on Super Niu, the reserve is 11 times that wager⁸. The reserve sits on the table alongside your bets and is not part of your wager; it is collateral.

This is the number to plan around. When you place a Double or Super Niu wager, you must also set aside a reserve on top of your bet, and that reserve is money genuinely at risk: if you have a losing hand, it may be forfeited in full, forfeited in part, or retained, depending on what the dealer holds⁷. So a round where you add these wagers puts more of your money on the table than the chips you place in the betting areas suggest.

If you win the round, the reserve comes back to you in full along with your winnings. If you lose, the reserve may be forfeited in full, forfeited in part, or retained, depending on how strong the dealer's winning hand is¹. The stronger the dealer's hand, the more of your reserve the house takes.

Payouts: 1 to 1 on Even, up to 12 to 1 on Super Niu

Here is the full payout table from the Hoiana rules. The 5% commission applies to winning Double and Super Niu payouts above even money; the Even bet pays flat 1 to 1 on every winning hand except Niu 6, where a 50% commission applies¹.

The pattern is clear: the Super Niu payout tracks your hand number exactly, so a Niu 7 pays 7 to 1 and a Niu 9 pays 9 to 1, with the special hands paying above the scale. The Double bet only starts paying more than even money from Niu 7 upward, and the Even bet is flat regardless of how strong your hand is.

A worked example: you bet 100 on Even, 100 on Double and 100 on Super Niu, and you win the round with Niu 9. You collect 100 on Even, 200 on Double minus 5% commission, and 900 on Super Niu minus 5% commission, plus your three stakes back, and your reserve is untouched. The same round won with Niu 3 would pay just 100, 100 and 300.

At Okada Manila, the Super Niu Niu Plus side bets work on a different mechanic: you bet on the three-card hands of other players or the dealer, with side bets starting at PHP 100 and payouts reaching 150 times².

When the reserve is forfeited, partly taken or retained

When you lose a round, the dealer's hand determines what happens to your reserve. The stronger the dealer's hand, the more the house takes.

For the Double bet reserve, the full amount is taken when the dealer's winning hand is Hoiana Niu Niu, Ultimate Niu Niu, Niu Niu, Niu 9, Niu 8 or Niu 7. When the dealer wins with Niu 6, Niu 5, Niu 4, Niu 3, Niu 2, Niu 1 or No Hand, the reserve is retained and returned to you¹.

For the Super Niu reserve, the scale slides with the dealer's hand⁶:

The outcome depends on the dealer's winning hand. On the Double reserve, the full amount is taken if the dealer has Hoiana Niu Niu, Ultimate Niu Niu, Niu Niu, Niu 9, Niu 8 or Niu 7, and it is retained if the dealer has Niu 6, Niu 5, Niu 4, Niu 3, Niu 2, Niu 1 or No Hand. On the Super Niu reserve, the full amount is taken when the dealer has Hoiana Niu Niu, and it is retained when the dealer has Niu 1 or No Hand¹.

This is why the game's real risk is not the wager you place but the reserve behind it. A losing round against a strong dealer hand can cost you up to 11 times your Super Niu bet on top of the bets themselves.

Playing at home, at a casino table or with a live dealer

The home game is the original. In its traditional form, players split five cards into three and two and compare against the dealer, with the same hand logic but usually simpler settlement: winners are paid, losers pay, and there is no reserve system at all. The Ha Tien Vegas rules describe this version, where both players' Niu Niu hands are compared by two-card value, then highest card, then suit⁹. Stakes are whatever the group agrees, and settlement is instant.

The casino table game adds the three-bet structure and the reserve. That is the version spread at Hoiana, and it is the one to study before playing, because the reserve rules mean your exposure is far larger than the chips in the betting circles¹. Ask the dealer about table minimums before you sit, and note that the Double and Super Niu bets are optional: you can play every round on the Even bet alone and never post a reserve.

The live-dealer version follows the casino rules but plays out on a streamed table, often with several seats and side bets on other players' hands, as with Super Niu Niu Plus at Okada Manila². We cover how these online versions work, and where they are legal, in our guide to playing Asian games online.

Wherever you play, the core skill is the same: look at your five cards and find the three that total 10, 20 or 30. Everything else, the rankings, the tiebreakers and the payouts, follows from that one arrangement decision.
