An unpublished ceiling is still a ceiling, just one nobody can check
A maximum win multiplier is a ceiling on a single spin's payout. It is not a target. Whether or not the studio ever states the number, somewhere inside Sweet Bonanza's math model that ceiling exists, because every RNG slot Pragmatic Play builds runs on a pay table with a fixed upper bound. The studio choosing not to state that number does not remove the ceiling. It removes a reader's ability to check it against anything the company actually said.
The same page is just as quiet on hit frequency. A high theoretical ceiling paired with an unstated hit rate tells a reader nothing about how often any of it is likely to matter across a normal session, and Sweet Bonanza's own page leaves that question exactly as open as the maximum win question.
That distinction matters most to anyone comparing two titles by their headline potential. A stated 25,000x on Sweet Bonanza 1000 and an unstated ceiling on the original are not comparable on equal footing, even when a review page shows a number for both, side by side. One of those numbers came from the company that built the game. The other did not, however many places repeat it.
