Must-hit-by explained
Must-Hit-By Progressives: Counters, Ceilings and Limits
A ceiling tells you where a feature or jackpot must occur under the game's rules. It does not tell you what your next spin will return, or make the amount on the display your money.

What the ceiling means
A monetary must-hit-by progressive displays a growing jackpot and a stated upper boundary. The award can occur before that boundary. Once awarded, the progressive normally returns to its reset value and a new cycle begins. Read the rules for the particular jackpot: an award ceiling is different from a display cap.
A hidden-trigger design is one possible implementation. GLI's progressive-jackpot testing standard describes both random events on individual plays and hidden thresholds selected within a range. The standard is a technical reference, not evidence that a particular casino's installed game uses one implementation.
A jackpot total alone does not establish a must-hit-by rule. The game title, award label and applicable rules need to agree. A feature counter may instead count collected symbols; a deadline for that feature does not make its variable bonus payout a fixed monetary jackpot.
Calculator assumptions
The current calculator models a monetary progressive using its current number, must-hit-by ceiling, counter rate and base payback. These are the four visible inputs. The counter-rate field uses dollars wagered per one-cent increase, not a percentage contribution. Those units cannot be interchanged.
The custom calculation uses a midpoint estimate for the award. Presets can use a different assumption, and the result names the method being used. A midpoint is a model assumption, not a promise that the jackpot will occur halfway through the remaining range. The tool does not discover the game's hidden trigger or independently verify its distribution.
The displayed estimate depends on the base payback and counter rate supplied. Default values are labeled as assumptions. An unknown return should remain unknown; a value from a different game or denomination cannot establish this one's return. A jackpot ladder or a photo cannot, by itself, supply every missing input.
The result displays an estimated base-game cost and expected return for the selected model. It does not expose a seed-value or bet-per-spin control, solve a combined multi-tier jackpot model, or calculate a variance-based bankroll. A calculation can be arithmetically consistent while its inputs still do not describe the real game.
Reading the display
Keep the current amount, the corresponding award label and any printed ceiling together in the same view. A Mini label beside one figure and a Major ceiling beside another are not one matched pair. A photograph that cuts off the label can leave an apparently clear number ambiguous.
Check whether the display uses dollars, credits or collected symbols. Denomination, selected bet and eligibility rules can affect what the figures mean. Similar cabinet art does not show whether the counters are independent, shared across a bank, or tied to one wager selection.
A counter that looks still during a short observation is not proof of a fault or a fixed jackpot. Display precision, the increment size and the game's rules affect visible movement. On a linked jackpot, other players can also change the shared display; that movement is not a measurement of the contribution from your own wager.
The counter-reading explainer separates the displayed object from the assumptions attached to it. Preserve the complete screen context when comparing a photo with a guide.
Two different meanings of trigger
The game's hidden award trigger and a guide's qualifying condition are different things. The first is part of the game mechanism. The second is an assessment made from stated rules and evidence. A guide condition does not reveal or change the hidden trigger.
There is no universal percentage of the way to a ceiling that establishes a valid conclusion for every game. The distribution, contribution mechanism, base-game return and eligibility can differ. A rule of thumb cannot replace missing information about the installed version.
Likewise, a counter near its ceiling does not establish the amount a player will ultimately receive after accounting for wagers. A feature deadline, a possible award and net session outcome answer different questions. Keep those distinctions when reading any calculator result or jackpot photograph.
Stopping and sunk costs
You can stop at any time. Earlier wagers are already spent; they do not create ownership of a future jackpot or an obligation to continue. Describing a possible future award as money you have already earned is misleading.
An expected-value estimate describes a model average, not the outcome of a particular session. It cannot justify overriding a spending limit, extending a session, or trying to recover losses. A loss limit limits further spending when followed; it does not ensure reaching an award first.
If the relevant feature is awarded and the display resets, the earlier reading is no longer current. The new screen must be understood on its own terms. Resetting does not establish a universal best or worst machine ranking.

Different counters and mechanics
The Buffalo Link guide illustrates a green collected-symbol counter above the reels. That count concerns a feature; it is not a dollar jackpot input. A photo of the jackpot ladder instead of the counter would answer a different question.
The Phoenix Link guide also distinguishes a collected-symbol reading from the monetary prizes on the screen. Related names, repeated symbols and the word “Link” do not make two machines use interchangeable rules.
Accumulated state and must-hit-by deadlines are separate concepts. A feature can store progress without being forced to trigger at a particular displayed total. Do not infer a verified mechanic solely because a game is absent from this site's catalogue.
Manufacturer and version
A manufacturer's name identifies the maker, not a universal jackpot model. Its different games, denominations and configurations may have different rules. Neither a familiar logo nor a familiar cabinet supplies a missing ceiling, return percentage or trigger distribution.
The manufacturer directory groups the machine guides we actually hold. Use the machine title and version to distinguish those records. The directory does not claim that every product from a listed manufacturer is covered, or that every listed game supports the monetary calculator.
An estimate is not a loss limit
Coin-in is total money wagered, including any returned credits wagered again. Net loss is different. Expected base-game cost is a modeled average, and cash available is a personal spending constraint. None is a substitute for the others.
Multiplying an average cost by an arbitrary number does not produce a guaranteed bankroll or a verified probability of avoiding ruin. Those claims would require a supported model of the return distribution and its assumptions. The current calculator does not provide that model.
A bounded progressive counter does not place the same bound on a person's losses. Payout size, qualifying wagers, other participants in a linked system and base-game outcomes all affect what happens during a session. Do not treat a ceiling as a promise to recover money already spent.
Frequently Asked Questions
Does must-hit-by mean the next spin will win?
No. A published ceiling describes the relevant feature or jackpot boundary. It does not reveal the next result, a particular player's payout, or whether that player's session will be profitable.
Does every must-hit-by game use the same trigger distribution?
No universal distribution is established here. A hidden trigger and a visible ceiling do not by themselves prove that all remaining trigger values are equally likely. A calculator's midpoint assumption must not be presented as a verified rule for every game.
Can I enter a collected-symbol count in a dollar-jackpot calculator?
No. A symbol count and a monetary jackpot have different units and may trigger different kinds of features. A result produced with incompatible inputs does not describe the machine.
Does the calculator measure my machine's return?
No. It calculates from the inputs and assumptions provided. Its base-payback and counter-rate assumptions are not measurements of a particular installed game.
Do earlier wagers require me to keep playing?
No. Money already spent does not create an obligation to continue or a guarantee of recovery. You can stop at any time. An expected-value estimate is not a reason to exceed a spending or time limit.
Is there a universal bankroll multiple that guarantees reaching a jackpot?
No. Expected wagering, expected base-game cost, cash available and maximum possible loss are different quantities. This calculator does not calculate a variance-based bankroll or a risk-of-ruin guarantee.
