Okay, back to the penny machine with the MP that starts at $9 and must hit by $10. It doesn’t matter if you are betting a block of 100 coins (pennies), a block of ten coins, or betting just one coin at a time, if the RNG has selected coin number 476, then when you get to and bet that coin number you will win the money in the meter.
Through Nevada Gaming Control stats we know that penny slots return anywhere from 86 to 94%, depending on location. But let’s say the machine in our example has a sign on it that says “This machine returns 90% to players.” What else can we tell about the machine?
Clocking the meter is pretty easy. If the meter rises 5 cents for every $5 in action it’s a 1% meter. How much of the payback is represented by the Mystery Progressive and how much of the payback is represented by the line pays?
In the case of the MP, since we know the coin number to trigger the MP is chosen at random, then we add the lower and upper parameters together and divide by two.
$9 + $10 = $19
$19/2 means the average MP awarded is $9.50
How much action does it take to move the meter from $9 to $9.50? It’s pretty easy. Since $1 in action puts a penny in the meter then $50 in action moves the meter to $9.50. So then we take the $9.50 average hit and divide it by $50.
$9.50/$50 = 19%
So we now know that we have a machine where the line pays represent 71% of the payback and the MP represents 19%.
MP’s come in a myriad of games, paybacks, upper and lower parameters for the Mystery Progressives, and meter speeds. If the meter speed in our above example were .5% then it would take 200 coin-in to move the meter one penny. The line pays would represent 80.5% of the payback and the MP 9.5%. And if the meter speed is 400 coin-in to move the meter one penny it would be a .25% meter. Then the line pays would represent 85.5% and the MP 4.25%.
