Must-Hit-By vs Persistent State Slots: Understanding the Two Main AP Types
Must-hit-by and persistent-state slots create edges in different ways. Here is how to scout them, price them, and avoid the obvious traps.
Two Different Hunts
Most slot AP opportunities fall into two buckets: must-hit-by progressives and persistent-state games. They both can be profitable, but they ask for different skills.
MHBs are more obvious. You read a number and compare it to a cap. Persistent-state plays are more visual. You need to know what the game is saving from one player to the next.
If you confuse the two, you will either overpay for obvious meters or miss quiet plays sitting right in front of you.
Must-Hit-By Progressives
How They Work
A must-hit-by jackpot is guaranteed to pay before a posted amount. A Major might reset at $250 and must hit by $500. As players wager, the meter climbs.
The AP question is simple: is the meter high enough that the expected jackpot value beats the cost of pushing it?
What You Need to Know
- Current meter value
- Reset value
- Must-hit cap
- Meter movement rate
- Base game RTP
- Bet size and bankroll risk
Common trap: A meter near the cap can still be bad if it moves slowly or the base game is expensive.
Examples
- Ascending Fortunes / Stack Up Pays: Multiple capped meters with different reset points.
- Dragon Link: Grand jackpot opportunities can be valuable, but competition is heavy.
- Quick Spin Platinum: Multiple progressives with tighter ranges.
Scouting Notes
MHBs are easy to scout and easy for other APs to see. If a number is obviously close, assume someone else noticed it too. Re-checking later can be better than forcing it now.
Persistent-State Games
How They Work
Persistent-state games save progress on the machine. A meter fills, symbols collect, or a feature gets closer. When the last player leaves, that progress stays.
The opportunity is to find a machine where someone else paid for most of the setup.
What You Need to Know
- What screen or meter matters
- How far the state is from reset
- Average bonus value
- Typical coin-in to trigger
- Whether the state can stall or disappoint
Persistent-state math is less clean because the payout is not always fixed. That is why screenshots and game-specific notes matter.
Examples
- Regal Riches / Prosperity Link: Colored meters persist and become playable at known thresholds.
- Buffalo Link: Collected symbols can create a playable state.
- Dragon Link / Autumn Moon: Orb collections can carry between players.
- 2-Minute Drill: Field progress persists.
Scouting Notes
Persistent-state plays are where a trained eye gets paid. A casual player sees a normal screen. An AP sees that the previous player left too early.
Side-by-Side
| Must-Hit-By | Persistent State | |
|---|---|---|
| Main signal | Jackpot amount | Saved progress or collection |
| Ease of scouting | Easier | Harder |
| Competition | Higher | Lower |
| Math clarity | Cleaner | More game-specific |
| Beginner fit | Good | Good after study |
Which Should You Learn First?
Start with MHBs if you need fast feedback. You can learn the meters and practice passing bad numbers.
Start adding persistent-state games once you can recognize cabinets quickly. That is where the floor gets less crowded. Most players will not know what they are looking at.
Practical Takeaway
MHBs reward number discipline. Persistent-state games reward pattern recognition. Learn both, but do not evaluate them the same way. A visible jackpot cap is a different animal from a half-hidden meter state.
