Double Zero Roulette wheel layout

According to Wikipedia, in MOST casinos

the layout of Single-zero wheel 0-32-15-19-4-21-2-25-17-34-6-27-13-36-11-30-8-23-10-5-24-16-33-1-20-14-31-9-22-18-29-7-28-12-35-3-26

and the layout of a Double-zero wheel 0-28-9-26-30-11-7-20-32-17-5-22-34-15-3-24-36-13-1-00-27-10-25-29-12-8-19-31-18-6-21-33-16-4-23-35-14-2

I have only ever seen a single wheel layout as above, in casinos in NZ, Australia, Macau, Malaysia and Singapore

My local casino in NZ has now introduced double zero roulette with the layout identical to that of a single zero wheel, but with the 00 between 5 and 10

The Crown Casino in Melbourne, Australia, according to their published rules may off double zero roulette with the 00 as per the sequence above, or may use the standard single wheel layout as above but with the 00 next to the 0

I am wondering why there are different variations in the double zero layout. Of course the house edge is unchanged but it seems strange that there are so many ways to present ther double zero wheel.

Can anyone enlighten me??

Trademarks, patents, or copyrights, perhaps?

Yes possibly, but its strange that there seems to be only one kind of single 0 wheel but many variants of the 00 wheel

Without spending time to research it, perhaps single 0 is in the public domain; and double 0 is not? It's been more than 120 years, but the "Happy Birthday" police are still out enforcing that copyright!

A penny here, a penny there; it all adds up...

In Monte Carlo they had an automatic roulette wheel with the double zero layout but with the double zero removed. So there were 2 red pockets next to each other.

I don't believe the reason is copyright because there is no copyright on a game that is centuries old. Maybe these roulette wheels are cheap Asian products. I have a little cheap automatic roulette toy with the single zero layout but they put the zero between 32 and 15 instead of 26 and 32. So my best guess is that they screw it up all the time or that a manufacturer wants his very "own" version of roulette, like a signature to distinguish itself from other mass products.

That makes it a trademark. If they see it elsewhere, they can sue for that. Less expensive than trying to get a patent or copyright, but with the same devastating legal effects if violated. A collector friend says that GI Joe dolls have some kind of anatomical defect on one of the hands. If someone tries to make a direct copy, it will be caught. If a collector does not see the defect, it's a fake.

The wheels are all genuine quality ones that I have seen everywhere I have been in a casino, no cheap imitations for sure.
