Editorial method
How Spinning House is researched, checked and corrected
We see the casino floor and the poker machine as one story. We build that story from primary papers. We skip the press releases.
Where the facts come from
Our primary sources are patent records, municipal and state gaming archives, and the published technical histories written by, or about, the manufacturers themselves. A claim about a 1963 payout mechanism, for instance, is checked against Bally's own engineering literature, not a later summary of it.
Each fact we publish is cross-checked against at least two source types before it appears. Where a patent record and a manufacturer's history disagree on a date or a detail, we say so in the text rather than quietly choosing a side.
What we leave out
We do not cover contemporary odds, current promotions, or operator marketing of any kind. If a claim cannot be traced to a dated document or a surviving object, a patent number, an archive folder, a machine still sitting in a collection, we leave it out, however tidy it would look on the page.
- Review cycle
Twice a year, or sooner
Every page is re-read against its sources each June and December, and again immediately if an error is reported.
- Correction method
Fixed in place, with a note
We correct the text itself and add a visible note stating what changed and when, rather than quietly editing or filing a separate errata page.
- Sourcing bar
Dated document or surviving object
A claim stands only if it traces to something specific we can point to, not to a general impression of how the story usually goes.
Independence and funding
Spinning House carries no advertising and no affiliate links. We take no payment, in any form, from a gambling operator, machine manufacturer or venue. The site is funded solely by the editor's own research work, which is also how we can afford to say, in plain prose, when the record is thin!
