# How does this work?

Maths goes wrong in the real world when we ASSUME certain parameters are CONSTANTS when they are VARIABLES.

This is how this trick works. We assume the cards above are constant.

Now look at both sets of cards again …………………

**Slot machine maths: **

**a lose lose date with the Pokies**

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:

### In Australia pokie machines must return between

# 85%

### and

# 90%

### 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.

# WRONG! WRONG! WRONG!

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

# NOTHING!

### 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.
