I will look to see if I have any more photos of this game. I know Monopoly Cash Flow plays on the dual BB1. This was released at the same time. This article states they are unlinked, which I assumed meant no progressive linked. So I got excited to know if this would work as well. Never seen this game in person.

New Multi-Line, Multi-Coin Non-Linked Video Participation Products
In June, WMS launched its first multi-line, multi-coin MONOPOLY themed participation game, Once Around Deluxe(R), designed on the CPU-NXT(TM) operating system in the Bluebird(R) cabinet to tremendous initial acceptance. At G2E, WMS will showcase its two newest multi-line, multi-coin CPU-NXT-based MONOPOLY participation games, MONOPOLY Cash Flow(TM) and MONOPOLY Reel Riches(TM). In the MONOPOLY Cash Flow bonus round, players are awarded free spins during which they accumulate as many properties as possible to maximize their bonus winnings. In the MONOPOLY Reel Riches bonus round, players roll the dice to advance MR. MONOPOLY around the game board to collect winnings by building houses and hotels as he advances.
