What Is Fish Prawn Crab?

Fish prawn crab — known in Chinese as Hoo Hey How (魚蝦蟹) and in Malay as Ikan Udang Kepiting — is a traditional dice-based betting game that has been played across Southeast and East Asia for centuries. The game uses three six-sided dice, each face displaying one of six symbols: fish (鱼), prawn (蝦), crab (蟹), rooster (雞), gourd (葫蘆), and coin (錢). Players place bets on which symbols they believe will appear when the dice are revealed, and winnings are paid based on how many of the three dice show the betted symbol.

Historically, the game was a fixture at Chinese New Year celebrations, temple fairs, and festive gatherings throughout Southeast Asia. Physical versions used a covered bowl containing the three dice, which a dealer would shake vigorously before lifting the cover to reveal the result. Digital versions replicate this experience with animated dice reveals and, at live casino platforms, physical dice shaken by an actual dealer and broadcast via streaming video.

The fish prawn crab game's enduring appeal stems from its extreme accessibility. The rules can be explained in under a minute, there are no complex betting systems to master, and the pace of play is fast. For experienced gamblers, the range of available side bets adds a layer of variety that prevents the game from feeling repetitive over extended sessions.

At Singapore online casinos, fish prawn crab is often grouped with fish hunter shooting games in the "fishing" or "Asian games" section of the lobby, reflecting the shared cultural heritage of this game category. Its presence alongside fish hunter titles makes it a natural option for players looking for variety during a session.

Fish Prawn Crab Rules Explained

Understanding the core rules of fish prawn crab before placing real money bets is essential. The following breakdown covers the standard rule set used at virtually all Singapore online casino versions of the game:

The symbols: The six symbols on each die face are fish, prawn, crab, rooster, gourd, and coin. Each symbol appears on exactly one face of each die, so the probability of any single symbol appearing on a given die is 1/6. With three dice, the combined probability that a given symbol appears on at least one die is approximately 42.1%.

The betting layout: Before each round, players place bets on the betting layout by choosing one or more symbols. There is no restriction on which symbols you can bet simultaneously. Some players spread bets across two or three symbols to increase their coverage of the possible outcomes, though this also increases the total stake per round.

Winning conditions: If one of the three dice shows your chosen symbol, you win 1:1 (you receive your stake back plus an equal amount). If two dice show your symbol, you win 2:1. If all three dice show your symbol, you win 3:1. If none of the three dice shows your symbol, your stake is lost.

Multiple bets in one round: You can place bets on multiple symbols simultaneously. Each bet is evaluated independently against the dice result. For example, if you bet S$10 on fish and S$10 on crab, and the dice show fish, fish, crab, your fish bet wins 2:1 (S$20 profit) and your crab bet wins 1:1 (S$10 profit).

The house edge: The standard house edge on a single-symbol bet in fish prawn crab is approximately 7.87%. This means the casino retains about S$7.87 on average for every S$100 wagered on single-symbol bets over time. This is higher than most fish hunter shooting game RTPs but lower than many traditional casino table games such as American roulette.

How to Bet on Fish Prawn Crab

Beyond the basic single-symbol bet, many digital versions of fish prawn crab offer additional betting options. Understanding these expands your strategic range and adds variety to your sessions:

Single symbol bet: The foundational bet — wager on one of the six symbols. Pays 1:1, 2:1, or 3:1 depending on how many dice show your symbol. House edge approximately 7.87%. The most straightforward option and suitable for all experience levels.

Two-symbol combination bet: Bet that two specific named symbols (e.g., fish and prawn) will both appear among the three dice. The probability of this occurring depends on which two symbols you select and is lower than a single-symbol bet. Payouts for combination bets are typically in the 6:1 to 8:1 range.

Any pair bet: Wager that any two of the three dice will show the same symbol (regardless of which symbol). This bet has a relatively high frequency of occurrence and typically pays 3:1 to 6:1 depending on the variant.

Specific triple bet: Bet that all three dice will show a specific named symbol (e.g., all three dice show crab). The probability of this outcome is 1/216 per specific symbol. Payouts are typically in the range of 150:1 to 180:1, making this the highest-risk, highest-reward bet in the standard fish prawn crab rule set.

Any triple bet: Wager that all three dice will show the same symbol, without specifying which. The probability is 6/216 or approximately 2.8%. Payouts are typically around 24:1 to 30:1.

For most players, particularly beginners, sticking to single-symbol bets is the most sensible approach. The payout structure is transparent, the house edge is known, and the gameplay is easy to follow. More experienced players who enjoy higher variance can explore the combination and triple bets once comfortable with the game's rhythm.

Fish Prawn Crab Strategy — Tips to Win

Because fish prawn crab is fundamentally a game of luck with no skill-based influence on dice outcomes, strategic thinking focuses on bet management rather than gameplay tactics:

Stick to single-symbol bets for better value. Despite the 7.87% house edge, single-symbol bets offer the most balanced risk-reward ratio in fish prawn crab. The combination and triple bets carry higher house edges in most versions of the game. For extended play sessions, single-symbol bets minimise the rate at which the house edge erodes your bankroll.

Avoid spreading bets across all six symbols. Placing bets on all six symbols simultaneously may feel like it guarantees a win, but it does not. In a round where the three dice show three different symbols, three of your six bets win at 1:1 and three lose. Your net position depends on how much you staked on each symbol. Spreading thin across all symbols generally produces a net loss because the house edge applies to the total amount wagered.

Set a budget and bet size before playing. Decide your session budget and use it to determine your per-round stake. A common approach is to bet no more than 2% to 3% of your session budget per round. With S$100 to play with, that is S$2 to S$3 per round. This pacing gives you 33 to 50 rounds of play — enough to experience multiple outcomes and bonus moments in live dealer versions.

Use the live dealer version for atmosphere. Many Singapore online casinos offer live fish prawn crab with a real dealer shaking physical dice on camera. The live format adds significant entertainment value and replicates the social atmosphere of traditional festive play. While the odds are identical to RNG versions, the live experience is often more enjoyable for extended sessions.

Treat fish prawn crab as entertainment, not investment. With a house edge near 8%, fish prawn crab is not a game where long-term profitability is realistic. Approach each session as an entertainment expenditure — a budget you are willing to spend for the enjoyment of playing — rather than as an attempt to generate income. This mindset keeps the experience positive regardless of outcome.

Responsible gambling: Fish prawn crab's fast pace and simple mechanics can make time pass quickly during a session. Set a time limit alongside your budget limit, and step away when either is reached.
