How To Hustle – Learn Coin Flip Tricks From A Sleight Of Hand Expert


This is the second in a three-part series on how
to turn yourself into “the house” and reap the benefits of a mathematical edge
in games that are less than fair but seemingly place the odds in the players’
(suckers’) favour.

I must re-iterate that these games are for
entertainment purposes only and as always, while I encourage you to play for
affordable stakes, it’s always good to share the secret when the game is over
so your suckers can enjoy the same benefits with fresh fish on another day.

Here we will take the flip of a coin and turn it
to our favour with some ingenious games that ultimately push the money in your

The Fun Of Coin Flips

I’ve written elsewhere about the master of crooked coin flips AKA “The Flipper” and the many ways he would manipulate a coin toss or secretly know the outcome.

It’s also possible to buy (or have made) a
“wobbler” – a coin that has been re-milled on the edge with a slight angle
towards one side so that, when spun on a hard surface, it favours one side more
than the other and, in many cases, the work is so heavy it’s almost impossible
to force a losing spin!

Such gaffs can be fun, and the above variation
was my preferred method for securing a free lunch by spinning a coin and asking
someone to call heads or tails while still spinning.

The bet was for who would pay for lunch and if
they called the winning side, I’d scoop up the coin and say, “I’m only kidding,
I wouldn’t force you to pay for this!”

But if they called the losing side I’d let it

What follows are games played entirely with fair coins and can be a great ongoing game or distraction between other gambling sessions and have been used as such by smart players and grifters for decades.

Coin Hustle #1 – Eight Coins Out

With eight pennies, propose a simple bet that
once all are flipped, spun or tossed in a random fashion, you will pay two to one
any time that the player throws four heads out of the eight coins.

A simple calculation makes four heads (or tails
if preferred) the most common outcome of eight 50/50 flips but in fact the odds
are absolutely in your favour, since you win if the result is one, two, three,
five, six or eight heads (or tails)!

I prefer to do this in a cup or glass (a glass
attracts attention and more suckers in the right scenario) and simply and
fairly spread out the coins once upended onto the table without changing how
they landed.

This is such a simple proposition that you can
play this edge for hours both winning and losing but always being ahead.

And if you can’t find any takers for a
two-to-one proposition like this, you’re probably not cut out for this kind of
friendly swindle!

Coin Hustle #2 – Threesomes

The same proposition can be made with just three coins and again is based on encouraging a simple fallacy.

With just three coins, point out that there are
only four possibilities when all three are flipped at random:

  1. Three heads.
  2. Three tails.
  3. One head and two tails.
  4. Two tails and one head.

Now state that if they fall all heads or all
they win, and you will pay two to one on any reasonable bet but if
the coins land with any other outcome they lose.

Personally, I prefer to randomise the coins in a
glass or cup but the result is three individual 50/50 propositions. You may
prefer to simply flip one coin three times, but the result is the same.

Think about this for a minute.

If there are only four outcomes, then you are
essentially offering them two to one on a 50/50 situation and that’s madness.

But be warned that if they’re smart enough to
think it over they will exit the logic trap you set up at the beginning and
realise that there are actually six losing outcomes and only two
winning possibilities
since each of the three coins has a 50/50 outcome.

You lose when the coins land:




You win if the coins land:







Think of it as individual rolls and it makes
sense but the beauty of rolling three coins at once is that this is harder to
intuit and many people will be blinded by your two-to-one offer on a game that
is actually three to one against the player.

Coin Hustle #3 – Penney’s Game

Finally, let me share a brilliant bit of mathematics that will guarantee a powerful edge almost by magic if you follow some simple rules.

As stated above there are eight possible
outcomes when flipping three coins and each outcome should be as likely as the

But for this version, only one coin is flipped
repeatedly until a chosen three-flip combination appears.

So, if the chosen combination is TAILS, TAILS,
TAILS, a single coin is flipped until three tails have appeared in a row. So it
might be flipped 10 times before this occurs in three consecutive flips.

Similarly with any selected possible outcome –
such as TAILS, HEADS, HEADS or HEADS, TAILS, HEADS – you keep flipping coins
and recording the outcome until three consecutive flips produces one of the
wagered results.

I hope you got that.

It can be confusing, but just keep flipping and
noting down the result until one of the wagered three-coin outcomes happens and
whoever bet on that combination is the winner.

So where is the scam?

Walter Penney discovered that a simple calculation based on your opponent’s choice of three-coin combination will place the odds firmly in your favour in the worst case, and seven to one in your favour for the best case scenario!

The secret is to make sure they choose their three-coin
combination first and then you state your three-coin combination based on their
choice as follows.

Whatever combination they choose, consider it as
A/B/C so if they nominate HEADS, HEADS, HEADS:




If they pick TAILS, HEADS, TAILS, then:




And so on.

Your nominated three-coins should be X/A/B
where X = the opposite of B.

I know this sounds complicated so let’s look at a
couple of quick examples.

For the two examples above X/A/B would be TAILS,
HEADS, HEADS (if the sucker nominates HEADS, HEADS, HEADS) and TAILS, TAILS,
HEADS (if the sucker wants TAILS, HEADS, TAILS).

So, another way of saying this is that you take
their choice (A/B/C) remove C (their third flip option) and simply add the
opposite of B (their second flip option) to the beginning of your three-coin

This means that X/A/B for their choice of HEADS,

Play with this for while with all the
combinations mentioned in the previous coin flip game above (Threesomes) until
you can quickly calculate X/A/B for all outcomes, then flip a coin to see how
often your three-coin combo will win against theirs.

Sure, it sounds complicated but all advantages
in gambling require a little extra work and understanding and if you can
decipher these instructions, you have a powerful winning strategy for a
seemingly simple game.
