Fan tan: buttons under a dome, counted by fours, from the Macau text

The page we opened is the Portuguese text of Despacho Regulamentar Externo n.º 58/2004, on the Macau gaming bureau site. The secretary named on the page is Tam Pak Yuen. The date on the dispatch is 12 May 2004.

The dispatch replaces Portaria n.º 211/80/M of 15 November. This file uses the 2004 text.

The Chinese text of the same dispatch loaded on the bureau's English path. It agrees on the 5 percent commission. This note follows the Portuguese wording.

Not a reel and not a bracket

The regulation is a count of buttons. It is not a slot math sheet, and it is not a fan contest with a prize for picking a winner. If a lobby tile uses the same two words for a reel game, that tile is a different product.

The casino games hub is the cluster page. This file has no affiliate link. We did not sit at a table, open a casino account, or time a cash-out.

The tools are a wooden or plastic wand, buttons with holes, two metal domes, and a table with two to four glass boards. The dealer separates a random set of buttons with one dome, covers that set, and places it in front. The other dome covers the buttons left aside.

Bets open only after that cover step. They close when the dealer rings the bell and says, out loud, that the covered buttons will be counted.

The dealer lifts the front dome and counts with the wand, four at a time. The winning number is what remains. If nothing is left, the result is four.

A light for that number comes on, and the buttons leave the table. A broken button is left out of the count. The text never prints how large the pile must be.

A studio copy of fan tan can use other equipment and other pays. We did not open a studio card, so that pay list stays not published. The screen number game is the draw-rule note.

The regulation says the winner keeps the stake and also receives a prize. The prize is not a replacement for the stake. Read every multiple that way.

Fan is one number, and the prize is three times the stake. Nim is two numbers, one to win and one to push, and the prize is two times the stake.

Nga covers two winning numbers and one push, and the last number loses. The prize is half the stake. Sé-Sam-Hong is three numbers, and the prize is one third of the stake.

Kuoc is the simple chance, two numbers, and the prize is one time the stake. A push returns the stake. The text does not print a commission on that return, so this note does not add one.

The Chinese lines read 3 to 1 on Fan, 2 to 1 on Nim, 1 for 2 on Nga, 1 for 3 on three numbers, and 1 to 1 on the corner. That is the same set of multiples.

The Portuguese line says 5 percent of the prizes revert to the bank. The Chinese line says the house takes 5 percent of the payout odds. Both sit on top of the prize, not in place of a published percent edge.

An edge needs the chance of each remainder. The dispatch never prints those chances. It does not say 1, 2, 3, and 4 are equally likely.

This page will not invent that fraction. A fan tan edge stays unpublished on purpose. The price a game keeps is the idea, once a probability is actually on the page.

A minimum stake is not published, and neither is the speed of a count. Nothing on the dispatch is a provably fair seed. A pit card that adds a figure is the source, not this file.

The two-card drawing game is a different banked game with its own drawing rules. A table streamed with a dealer is the lobby category a studio version would sit in. Neither page supplies a button-game edge.

The dispatch prices a chance against the bank. A house in another city can post another list. This site's wheel prices a stake against other players, and the fee is in the rules here.

Do not paste a fan tan multiple onto the wheel. The three-times prize belongs to the 2004 text.

How PvP compares: the button count pays a prize from a regulation. Roulette pays from a 33-pocket wheel, 16 Purple, 16 Silver, and 1 Green.

Purple and Silver pay 2x, then 5 percent comes off that winning payout, so a hit keeps 1.90 times the stake. Sixteen divided by 33, times 1.90, minus 1, is about −0.0788.

That is the 7.88 percent edge on those two pockets. Green pays 14x. This page does not quote a Green edge.

A settled round can be checked on the fairness page. The check matches this site's commit. It does not audit a Macau table.

Balances are US dollars, funded with Bitcoin or with USDC or ETH on Base. Cash-out minimum is $20 in BTC, USDC, or ETH.

We did not time a cash-out. The joker-card deal is the two-side card game.

These pictures are arithmetic on the dispatch, or a fee from this site. None of them is a fan tan result we watched.

Example 1 — Fan on $20. The prize is three times the stake, $60, and 5 percent of that prize is $3.

The player keeps the $20 stake and $57 of the prize, $77 in all. That $77 requires the single number to win. The dispatch does not print how often it wins.

Example 2 — Kuoc on $20. The prize is one time the stake, $20, and 5 percent of that prize is $1.

The player keeps the $20 stake and $19 of the prize, $39 in all. A push is a different case, and the text does not cut 5 percent from a returned stake.

Example 3 — Purple payout. A $10 Purple stake that wins pays 2x, which is $20. Five percent of that payout is $1, so the player receives $19.

One Purple win does not reveal the 7.88 percent edge. Most Purple stakes lose.

A glass dome and a wand do not prove the 2004 prize list. Read the card on the table you are at.

• [ ] Confirm you are 18, or older if the pit sets a higher age.
• [ ] Confirm the game is buttons counted by fours, not a slot and not a fan contest.
• [ ] Bets are closed when the bell rings, if this dispatch is the rule in use.
• [ ] A remainder of zero is scored as four, if the card says so.
• [ ] Fan is three times the stake plus the stake, only if the card prints that.
• [ ] The 5 percent cut applies to the prize, not invented onto a push.
• [ ] Leave the chance of each remainder unpublished when the card is silent.
• [ ] Leave a studio pay list unpublished when you have not opened it.
• [ ] Do not treat a streamed multiple as the 2004 prize.
• [ ] Set a loss stop before the first stake.
• [ ] If the count becomes a chase, call 1-800-GAMBLER.
• [ ] Recompute a round on this site's fairness page, and do not ask it to audit a button table.

A fan tan chance can lose the stake. The three-times prize is a price for one winning number, not a plan, and the 5 percent cut makes the net prize smaller than the headline multiple. The regulation does not owe the next count a remainder.

Do not play if you are under 18. The dispatch we opened does not print a minimum age, so the door you are standing at can be stricter. Do not play where the game is illegal.

Do not stake rent, savings, or money with a due date. Do not play to get even. Why a cold run is not a credit is the general point.

This page is an editorial note, not a statute reading for your city, and not a coupon. This site does not offer the button game.

If play stops being a bounded spend, call 1-800-GAMBLER and open responsible gambling.
