How did you choose these must-hit-by machines?

Each machine is scored on its advantage-play trigger, data completeness, and mechanic, then ranked by which offers the strongest repeatable edge — full criteria are in the 'How we ranked these' note above.

Are these must-hit-by slots actually a play?

Yes — every machine on this list has a real advantage-play trigger or persistent state that, under the right conditions, swings the math in the player's favor. None of these are theme picks. Each entry links to a full guide with the play-at threshold and exit rule.

How often is this list updated?

We re-rank when machines are added, when verification status changes, or when a machine is retired — so the list stays current.

About this list

Must-hit-by progressives are forced to pay the jackpot before a stated ceiling. When the counter sits high, the math swings in the player's favor — these are the machines we track most closely.

How we ranked these

We pulled every must-hit-by machine in our database, then sorted by trigger value (the threshold where the counter is meaningfully close to the cap). Lower triggers mean a quicker decision and faster sessions; higher triggers mean a fatter top tier when the counter heats up.
