I was there on Sunday afternoon. At that time all four machines were in play, and not by collectors. The hotel guests were playing to get a souvinir of their visit and they seemed to be going fast. While I was there, they refilled one machine with 200, and all the other machines were down at least 3/4 of the way. I estimate that they have gotten rid of about a third of the run of 1750 of the first design. The tech that I spoke with could not give me an answer regarding why they are only putting in one design. If I were to hazard a guess, I would say that the casino, does not want to run out of a design and have complaints about only having one or two designs left in the machines, when it shows that there are three designs. With a run of 1750, they can be thru that design and into a new design within a couple of weeks, three weeks on the outside. Plenty of play on the machines and few complaints except from collectors. I averaged somewhere between $15 and $20 a strike on the machine I waas playing. Good luck playing.
