Introduction

A must-hit-by jackpot, sometimes called a mystery jackpot, is one that is guaranteed to hit by a certain point. There are two good things about a large jackpot:

  1. The jackpot itself is larger.
  2. The probability of winning it is greater.

As with any progressive game, at some point the jackpot becomes large enough to sway the odds in the player's favor. This page will examine these 'target points' on some new slots by WMS with mystery jackpots. If you're interested in must-hit-by progressives on Ainsworth slots, please see my separate page on that.

This page assumes that a jackpot is equally likely to trigger anywhere between the starting value and must-hit-by maximum. This seems to be true for all makers except AGS. The reader should be warned that AGS must-hit-by jackpots tend to hit near the must-hit-by-point. For example, on a version of River Dragons, where the large jackpot starts at $4,000 and must hit by $5000, I calculate the average point it does hit is $4,945.49. So, please do not apply the information in this page to AGS machines.

General Rules

Following are generally how must-hit-by progressives work.

  1. The jackpot starts at a defined minimum amount.
  2. A point at which the jackpot will hit is randomly chosen on a uniform distribution between the starting value and maximum possible jackpot.
  3. A certain percentage of money bet, known as the 'meter rise,' will be directed towards the jackpot.
  4. When the meter crosses the predestined win point the player will be awarded the jackpot.

The WMS jackpot games are different from the usual Mystery Jackpot games in two ways:

  1. There are two jackpots.
  2. The meter rises by the amount won, not the amount bet.

On the WMS games, it is my understanding that the Minor jackpot starts at $25 and must hit by $50. The Major jackpot starts at $200 and must hit by $500. Based on my own play, the rate of meter rise, for each meter, is 0.00582 times money won.

These two images below show two versions of the pertinent rule screen on the WMS games.

Math

The general formula for the Target Point can be given as:

Bally slot machine repair manuals. For slant-top games it will be located below the armrest on the right hand side. On upright games, the tag is located on the lower right-hand side.

Must hit by slot machines t = m × (h + r) / (h + 2r), where:

t = Target Point
m = Max jackpot
r = Rise of meter rate
h = House edge of game (taking into consideration the average value of the progressive)Musthit By Slot Machines

An unknown piece to this equation is h, the house edge of the game. No casino is going to tell you exactly what a given slot machine is set to. So, you may have to resort to industry averages. The following table shows the averages for Clark County, Nevada (where Las Vegas is). You can see for penny slots, which Mystery Progressives tend to be on, the overall house edge is 10.77%.

Although the information is a bit dated, you may wish to also consider the returns of random games I sampled in my page on Slot Machine Odds in Las Vegas. All things considered, I think it is safe to assume a house edge of 8% to 12% in Las Vegas. The nicer the casino and closer to the Strip the casino is, the higher the house edge will generally be. Outside of Vegas, you're on your own.

WMS Target Points

The math for the WMS games gets rather complicated because of the two jackpot and that they go up by amount won, not amount bet. So, you'll have to take it on faith that the tables below are correct.

AGS Warning

This page assumes that a jackpot is equally likely to trigger anywhere between the starting value and must-hit-by maximum. This seems to be true for all makers, except AGS. The reader should be warned that AGS must-hit-by jackpots almost never hit until they are near the must-hit-by point. For example, the large jackpots are supposed to hit by $5,000, but it is rumored in the advantage player slot community that they rarely hit below $4,990. So, please do not apply the information in this page to AGS machines.
