Slot machine maths:

a lose lose date with the Pokies

slot machine reels

According to Tom Vanderbilt in The Guardian ( Slot machines: a lose lose situation, 8 JUN 2013)

Once seen as a harmless diversion, hi-tech slot machines now bring in more money than casinos – and their players become addicted three times faster than other gamblers.

 Here’s how the math works:

slot machine 2

In Australia pokie machines must return between




of money gambled.

But here is the catch. If you start out with $300 that means, surely, you’ll go home with$255 in your pocket less some for the big payouts.


According to ex-gambler Tom Cummings you’ll probably go home with


In his article, Poker machine maths, (ABC, The Drum, 27 MAY 2011) it is not unusual for someone to start with $300 but put $3,000 into the  machine over 4 – 5 hours. 

Here’s the sting. According to the poker machine, $3,000 was gambled, and $300  was kept (by the slot machine). That means that the machine paid out $2,700… which is the 90 per cent return.

That’s one pension cheque gone for the week.

Warren Buffett has called

gambling in general a 

“tax on stupidity”


or a way of fleecing those who don’t do the maths.


Zombie Maths 12: Mean, Median and Mode

December 13, 2011

Zombies don’t bleed but Hollywood keeps splattering Zombies in FAKE BLOOD in movies. So every Zombie must know the cost of FAKE BLOOD.

So much FAKE BLOOD seems to be sold in America we have to use American volumes:

1 US fl oz = 29.6 ml

1 US pint = 16 US fl oz =  473 ml

1 US gallon = 8 US pints = 3785 ml = 3.79 litres

These are approx values as  manufacturers round off conversions from fl oz to ml.

Mathspig found 3 types of fake blood out there but Halloween Blood, Stage Blood and Movie Blood.

Based on all you need is love by Lennon/McCartney

No need for you to pray, you can learn how to do the maths

There’s nothing you can graph that won’t astound.

No x you can find that can’t be found.

No reason to sigh but you can learn how to love pi

in time – It’s easy.

All you need is maths, all you need is maths,

All you need is maths, maths, maths is all you need.
