Fish Prawn Crab Odds: The House Edge Behind Hoo Hey How

Fish Prawn Crab looks like a coin flip: three dice, one chance in six each, so half the time your symbol should show. It doesn’t work that way. On the classic single-symbol bet, the banker keeps 7.87% of everything staked, and you lose 57.9% of all rounds outright. Below we show the full odds, why the game feels like 50/50, how the online versions in our directory compare, and how to check any paytable yourself in 30 seconds.

How Fish Prawn Crab is played

The game goes by many names. In Malaysia, Singapore and Hong Kong it is Hoo Hey How (魚蝦蟹, “fish-prawn-crab”). In Vietnam it is Bầu Cua Cá Cọp. The British sailors’ version is Crown and Anchor, and the American carnival version with numbered dice is chuck-a-luck.

The rules barely change between versions, as described in Wikipedia’s Hoo Hey How entry:

1. A mat shows six symbols (sets vary: fish, prawn, crab, rooster, gourd, plus a coin, deer, stag or tiger).
2. You put your stake on one or more symbols.
3. The banker throws three dice, each marked with the same six symbols.
4. If your symbol shows on one die, you win 1:1. On two dice, 2:1. On all three, 3:1. If it doesn’t show, you lose the stake.

Takeaway: it is one bet repeated three times on the same dice — and that overlap is where the edge hides.

Fish Prawn Crab odds: every result on one symbol

Three dice give 6 × 6 × 6 = 216 equally likely results. We counted every one of them in Python (checked 31 Oct 2026). Here is what happens to a 1-unit bet on, say, Fish:

That is an RTP of 92.13%. The same figures appear in the Crown and Anchor and Hoo Hey How entries on Wikipedia and on the Wizard of Odds chuck-a-luck page.

Your symbol shows at least once in only 91 of 216 rounds — 42.1%, not 50%.

Takeaway: RM100 staked on the classic table costs you RM7.87 on average, and most rounds are straight losses.

Why it feels like 50/50 (and isn’t)

The intuition goes: “Three dice, each has a 1-in-6 chance, so 3 × 1/6 = 1/2. Even money on a half chance is fair.” Half of that is true. On average your symbol does turn up 0.5 times per round. The trap is in how those appearances are spread out.

The 108 vs 125 count

Picture all 216 results played once, with RM1 each time:

1. Count every die that shows your symbol across all 216 results. There are exactly 108 — that is the “half” from 3 × 1/6.
2. Each of those matching dice pays you RM1. So the game pays out RM108 in winnings.
3. But those 108 matching dice are bunched together. Doubles and triples put two or three of them into a single round, so they cover only 91 rounds.
4. That leaves 125 rounds with no match at all, each costing RM1.
5. RM108 won minus RM125 lost = −RM17 over 216 rounds. That is the 7.87%.

A fair game would need as many losing rounds as matching dice. Because doubles and triples “waste” dice on rounds you were already winning, the losing rounds always outnumber them by 17.

What bigger triple payouts do to the edge

Some tables pay more when all three dice match. The Wizard of Odds lists the edge for each triple payout, keeping 1:1 and 2:1 for one and two matches. We re-checked every row with our own count:

The formula is simple: with 1:1 and 2:1 kept, the edge is (20 − triple payout) ÷ 216.

The VIP Fish Prawn Crab figure in our directory

In our directory data (checked 31 Oct 2026), VIP Fish Prawn Crab by Hotdog Gaming is a table game listed at an RTP of 97.21%, with bets from 5 to 2,000. The provider describes it as three dice and six symbols, an “enhanced version” with “more betting options”.

That 97.21% is the provider’s figure. We don’t know which bet it applies to, and we have not seen its paytable. To reach roughly 97.2% on the single-symbol bet, a triple would need to pay about 14:1. That is maths, not a claim about the real game. Check it yourself:

1. Open the game’s paytable or help screen.
2. Find the payouts for one, two and three matching dice on a single-symbol bet.
3. Calculate: (75 × one-match payout + 15 × two-match payout + three-match payout − 125) ÷ 216.
4. The result is your edge on that bet. A negative 0.0787 means 7.87%.
5. Compare it with the listed RTP. If they differ, the headline figure belongs to another bet. Our RTP calculator turns any RTP into expected cost per session.

Win Win Fish Prawn Crab is a slot, not the dice game

Win Win Fish Prawn Crab, also by Hotdog Gaming, only borrows the theme. In our data it is a 10,000-ways slot with an RTP of 96.72%, volatility 2 out of 5 and a max win of 3,672×. Its results come from reels, not three dice, so the table above does not apply. A slot’s RTP is spread over rare big hits, so it plays very differently from a 1:1 dice bet.

Takeaway: the edge depends entirely on the triple payout, so read the help screen before you trust any headline RTP.

Fish Prawn Crab tips that don’t work

Search for “fish prawn crab tips” and you will find betting systems. None of them change the maths:

• Cover all six symbols. With RM1 on each, every die pays one of your bets. Three different symbols: you get RM6 back on RM6 — break even. A double: RM5 back. A triple: RM4 back. You can never come out ahead, and you still lose 7.87% on average.
• Follow the “hot” symbol. Dice have no memory. Fish showing three rounds in a row says nothing about the next roll — the same gambler’s fallacy we tested for slots.
• Two-symbol combination bets. If your table offers one at 5:1, both symbols appear in 30 of 216 results. That is a 16.67% edge — more than double the single-symbol bet.
• Bet sizing systems. Doubling up or flat betting changes how the swings feel, not the 7.87% you pay on every unit staked.

Takeaway: there is no Fish Prawn Crab strategy that beats the house edge. The only lever is the paytable, and you don’t control it.

Fish Prawn Crab vs sic bo and roulette

Sic bo uses the same three dice, so its single-number bet is mathematically the same as a Fish Prawn Crab symbol bet. Here is what each costs, using the figures from our sic bo house edge guide and roulette house edge guide:

What does 7.87% feel like? We calculated the exact distribution for 100 rounds of RM10 on one symbol (RM1,000 staked). The average result is −RM78.70. You finish ahead 22.5% of the time, exactly even 2.7%, and behind 74.7%. After 1,000 rounds, the chance of being ahead drops to 1.3%.

Takeaway: the classic game is one of the most expensive common dice bets. The longer you play, the more surely the edge shows up. Our guide to why the house always wins explains why.

Play it as a family game

For many families this is a festival game, not a casino game. Saigoneer lists bầu cua among the board games most tied to Tết. Houston Landing reported Vietnamese-American families playing it at home for small cash bets during the 2025 Lunar New Year.

At home, the banker role usually rotates, so the edge moves around the table. Online, the operator is always the banker, rounds come much faster, and there is no end to the evening. A few ground rules help:

1. Keep stakes small enough that losing all of them is fine.
2. Take turns as banker at home games.
3. Decide before you start when you will stop.
4. Don’t move from the family table to an online version to “win it back”.

If chasing losses sounds familiar, take our two-minute gambling problem self-check.

Takeaway: RM20 between cousins is entertainment. Hours of fast online rounds is where the 7.87% adds up.

Are Bầu Cua Cá Cọp odds the same as Fish Prawn Crab?

Yes, if the payouts are the same. The symbols differ by region, but three six-sided dice and 1:1 / 2:1 / 3:1 payouts give the same 7.87% edge.

Is there a Fish Prawn Crab strategy that works?

No. Every bet has a negative expected value, and dice have no memory. Covering all six symbols can never win money; at best you break even on a round.

Why is the VIP Fish Prawn Crab RTP higher?

The provider lists 97.21%, but we don’t know which bet that figure covers. Open the game’s paytable, find the single-symbol payouts and use the formula above to get your real edge.
