This is something I have cogitated on for a long timw. Why are never odd numbers of decks used? Why do no casino offer 3, 5 and seven deck games? The only exception is the odd one deck game. Doesn't make any sense to me.
... in continuous shufflers. There either are or have been a few 5 deck games in Las Vegas CSM's. I've never seen odd numbers of decks used for blackjack in any other context, except for single deck games.
... has 20-25 5 deck tables. Also 1 and 2 decks. No 4, 6, 8 ...
Bowler, WI also has 5d.
The only thing I've never seen is 3d. I think 3d is just big enough they'd have to use a shoe, so you'd lose the sales "pitch," yet you'd be shuffling all the time.
What's the reason of why odd deck games are so rare? I can see why, regarding the shuffle masters, since it might have something to do with the design and efficiency of using odd decks. But, in "non-shuffle masters games", does anybody know the reason?
