How to Read a Must-Hit-By Slot Machine Meter
A must-hit-by meter gives you more information than a standard progressive because it has a stated upper limit. The useful skill is learning what the numbers actually tell you—and what they do not.
Start with the three visible numbers
When you find a must-hit-by progressive, identify three values before doing anything else:
- Reset or starting value. Where the jackpot begins after it awards.
- Current meter value. The amount displayed right now.
- Must-hit-by maximum. The posted upper value by which the award must occur.
Those three numbers tell you where the current state sits inside the jackpot's allowed range.
Step 1: Confirm that it is actually a must-hit-by meter
Do not assume every growing progressive is must-hit-by. Look for language such as Must Hit By, Must Award By, or an equivalent game-specific statement that establishes a maximum.
A regular progressive can rise without a published hard ceiling. A true must-hit-by meter gives you a bounded range.
Step 2: Read the current value—not the animation
Slot displays are designed to look exciting. Pots may glow, characters may move, and meters may appear almost full. For AP evaluation, the actual number matters more than how dramatic the graphics look.
Write down or mentally note the live meter value. Comparing exact numbers is much more useful than deciding that a display simply “looks close.”
Step 3: Calculate the visible remaining range
The simplest useful calculation is:
Remaining range = Must-hit-by maximum − Current meter
This tells you how much visible meter space remains before the published ceiling.
It does not tell you the exact number of spins remaining, the hidden trigger point, or whether the state is positive expected value.
Step 4: Compare the current state with the reset
A meter immediately after reset is very different from the same meter near the top of its range. Comparing the current value with both the reset and the ceiling helps you understand how advanced the state is.
You can think of the meter as answering two separate questions:
- How far has the jackpot progressed from its starting point?
- How much published range remains before the maximum?
Step 5: Confirm what wager qualifies
This is where beginners often make a costly mistake. A strong-looking meter is only relevant if the wager you are making actually qualifies for the jackpot or feature being evaluated.
Before using any strategy assumption, check:
- required bet level
- denomination
- whether the progressive is active at that wager
- whether every bet level contributes equally
- whether the jackpot or feature value changes with denomination
Step 6: Determine whether the meter is individual or shared
Some must-hit-by progressives belong to one machine. Others are linked across multiple machines or player positions.
If several players can qualify for the same award, another player may trigger it before you do. That matters when evaluating the practical value of the state.
Step 7: Understand what the meter does not show
A visible MHB meter usually does not directly tell you:
- the exact hidden trigger point
- the exact number of spins until the award
- the machine's complete base-game return
- the expected cost of reaching the trigger
- the exact breakeven entry point
This is why reading the meter is the beginning of an AP evaluation—not the entire calculation.
Why “95% full” can be misleading
It is tempting to convert every MHB state into a simple percentage and use one universal rule. That can be dangerous.
Two jackpots can both appear to be 95% through their displayed range while having very different:
- wager costs
- meter increment rates
- jackpot amounts
- base-game returns
- linked-player competition
- variance
The visual percentage is useful context, but it is not a universal entry criterion.
Must-hit-by is not a countdown
This deserves repeating because it is one of the most common misconceptions.
A meter close to its maximum does not mean the jackpot must hit within the next few spins.
The maximum tells you where the progressive is required to award by. The feature may trigger earlier, and the exact short-term timing remains uncertain.
How hidden trigger systems can work
One documented must-hit-by model uses a randomly predetermined award point somewhere between the starting value and the maximum. Qualifying contributions increase the meter, and the award occurs when play moves the progressive through that hidden point.
The Nevada Gaming Control Board describes an MHB configuration using a starting amount, a maximum must-hit-by amount, and an incrementation rate, with an RNG-selected predetermined award value.
That is useful for understanding the concept, but you should not assume every slot product uses exactly the same implementation without confirming the rules for the specific machine.
A practical scouting checklist
When you walk up to a must-hit-by game, use this sequence:
- Identify the jackpot or meter.
- Confirm the must-hit-by maximum.
- Read the current value.
- Identify the reset or starting amount if available.
- Calculate the remaining visible range.
- Check denomination and qualifying wager.
- Confirm whether the meter is shared.
- Verify the exact game/configuration before applying strategy.
Example: reading the state correctly
Suppose you see two identical-looking machines.
Machine A has only recently moved above the reset value. Machine B is much closer to the posted must-hit-by ceiling.
Machine B clearly has the more advanced visible MHB state. But that observation alone is not enough to say “play Machine B.” You still need to know the wager cost, qualifying bet, jackpot economics, competition, and game-specific entry criteria.
Examples of machine-specific must-hit-by mechanics
Must-hit-by concepts can appear as traditional dollar progressives or as game-specific counters.
For example, the Phoenix Link guide covers a persistent Phoenix counter with a stated 1,888 upper limit, while 88 Fortunes: Emperor’s Coins combines must-hit-by jackpots with additional visible Free Games meters.
The mechanics can look similar at a high level while still requiring different entry calculations.
What actually determines a play/pass decision?
The public meter reading gives you the observable state. The real AP decision asks a harder question:
That is why APWebsite separates public education from machine-specific entry criteria.

Frequently asked questions
What numbers should I read first on a must-hit-by machine?
Start with the reset or starting value, the current meter, and the posted maximum. Then verify denomination and qualifying wager.
How do I calculate the remaining meter range?
Subtract the current meter value from the must-hit-by maximum. This gives you the visible remaining range, not the number of spins remaining.
Does a high meter mean the machine is positive EV?
No. It means the state is more advanced relative to the meter range. Whether it is actually attractive depends on the economics of the exact game and wager.
Can a must-hit-by jackpot hit before the maximum?
Yes. The maximum is an upper boundary. The award can occur before the meter reaches that value.
Should I use the same entry percentage on every must-hit-by slot?
No. Different games can have different wager costs, meter behavior, returns, jackpot values, competition, and configurations.
