Slots Tutorial: The rate of wins on multi-line slot machines.
> DR. HARRIGAN: This is a slot machine game called Moneystorm. It’s a popular game in Ontario. It’s a multiline game. What that means: you can wager on one line, or multiple lines. If you’re wagering on one line, it’s just the middle line, which normally means you need two or three symbols starting from the left before you can in a prize. But you can choose wager on to up to 20 lines, so if you wagered on two lines, then a winning prize would be if you had two or three symbols on this line or to or three lines on this line, or both.
Similarly, you could go up to three lines, and all lines would be in play. And, incredibly, you’ve got 20 different lines that you can wager on. And when you’re wagering on 20 lines, you have a very high chance of winning something, because one of those lines or two or three of those lines could win something. So, let’s just take a couple spins. [music] [winning sounds] Here I have a small win, I wagered 20 and I won 6.
[music] [winning sounds] This is an interesting one, I’ve had quite a few line wins. Each of the line wins is 2, so I have a total win of only 18, but we have a lot of wins within that 18. So, on my wager of 20, I have a net loss of two but I have 9 individual wins. The other thing we can do, is we can change the number of credits wagered per line.
So I was wagering on the previous spins 1 credit per line, for a total of 20 credits. If I press 2, I’m wagering 40 credits. Similarly, I could press 3,4, or 5 and be betting 60, 80 or 100 credits.
Each Moneystorm game in Ontario makes about 125 000 dollars per year. One thing that’s interesting about these machines, given that they make a lot of money, is how often you win something. When you’re wagering on 20 lines on Moneystorm, you’re winning something on about every second spin.
We did a trial, we played the machine for 10 000 spins and we got roughly 5000 wins of ‘something’. Many of those wins are less than the wager, but they’re still a ‘hit’ of some kind. It’s incredible to us, to think about the effect on the player of winning ‘something’ so often, and yet it’s the machine that’s evidently making the money, and not the player.
