AP Glossary
WhatIsFloor?
The starting or reset value of a progressive meter — the lowest point it returns to after a jackpot hit. The distance between the floor and the current meter value indicates how much has been contributed by players since the last hit.
Why It Matters
Why this matters for advantage play
The floor anchors the math on every progressive AP play. The current meter minus the floor tells you how much player-funded excess has been deposited. That excess is what you're competing for, and the lower the floor relative to current meter, the more value sits in the pot.
Cross-Reference
Related terms
Ceiling
The maximum value a must-hit-by progressive can reach before it is guaranteed to pay out. The closer a progressive gets to its ceiling, the higher the expected value of playing that machine.
Reset Value
The value a progressive meter returns to after being won. Also called the floor or seed value. The difference between the current meter and the reset value represents the player-funded excess that contributes to advantage play opportunities.
Progressive Jackpot
A jackpot that increases with each bet placed, funded by a small percentage of each wager. Progressives can be standalone (single machine) or linked (multiple machines). When a progressive grows high enough above its reset value, the added value can push the total RTP above 100%.
MHB (Must-Hit-By)
A progressive jackpot guaranteed to trigger before reaching a specified ceiling value. MHB progressives are the most mathematically analyzable form of advantage play because the ceiling creates a known upper bound for expected cost calculations.

Frequently Asked
Common questions about floor
Yes. The terms are used interchangeably. Some manufacturers also call it the 'seed' value.
Watch the meter for a hit and record the value it resets to, or consult published par sheets for the game. On many cabinets the floor is also shown on a secondary screen or help page.
Not necessarily. High floors often signal slow meter-rate games where the gap between floor and ceiling is small, which can still leave most of the time at -EV unless the meter has climbed substantially.
