Gambling games discrepancy

Postby Kagazahn В» 09.03.2020

.

It's a common sight on casino floors: patrons jumping from slot machine to slot machine before eventually hunkering down at a game that's due for the next big payout. But can players -- even the regulars who frequent a particular property -- really tell the difference between the house edge on one game from that of another?

At least not according to a series of recent studies led by Anthony Lucas, a UNLV Hospitality College professor and former gaming industry operations analyst. For the past several years, Lucas and colleague Katherine Spilde from San Diego State University have taken to casino floors on multiple properties in the U. Their results contradict long-held beliefs by casino operators about a player's ability to detect differences in how much -- and how often -- a slot machine pays.

This is where our work takes on a Moneyball-like aspect -- questioning the wisdom of widely held beliefs when data show that a new way of thinking may be better. In their latest study, the UNLV-led research team compared two pairs of reel slot games at a "locals" casino in suburban Sydney, Australia, where all wagering occurs on electronic gaming devices. Their process is relatively straightforward: take two identical slot machines, positioned in similar places on a casino floor, but vary the par -- the percent of total coin-in that the machine keeps over time.

But in the short term, this rarely happens, increasing the difficulty of par detection. For this study, researchers compared the daily performance of pairings for the games "Tokyo Rose" and "Dragon's Fortune X" over a nine-month period. The pars within each pairing ranged from 7. Researchers measured daily coin-in for each machine as well as its T-win, a formula that multiplies coin-in and par to calculate a machine's expected value, or its theoretical win.

If, over the course of the nine-month test, regular players could detect a difference in the pars, this comparison would reveal whether and how much players migrated from higher par to lower par games.

As Lucas predicted, differences between the high and low par games remained stable throughout the length of the study, which meant that there was no statistically significant indication of play migration. And while the lower par machines had more coin-in over the course of the study period, the T-win was greater on average for the high par machines.

The positive impact from the elevated T-win on revenue for the higher par machines more than compensated for the decline in coin-in on those machines. The results were also consistent with findings from the team's previous studies, which analyzed 11 pairs of games over days at gaming properties in U.

Pars are an important factor for casinos looking to optimize revenues, as the bulk of slot revenues come from reel slots, and a lion's share of a casino's overall profits come from slot operations.

While there are exceptions to this rule, it is true for most of the world's casinos. That's where industry perspective is mixed, as operators have expressed concerns that short-term gains from higher pars could lead to long-term losses as players leave perceived "tight" slot floors for the greener pastures of their competitors. To account for this concern, researchers extended length of time from previous work, from six months to nine months.

They also expanded the difference in pars between matched pairs from 4. In a concurrent study, the researchers compared the Australian data with four, two-game pairings at two similarly situated casinos in Mexico. Par differences for those games were even more drastic -- ranging from 7. Despite these factors, in both instances the results still found no evidence of players moving away from higher-par machines to their low-par counterparts, and the high-par games continued to post substantially greater revenues.

The contrast of monetary wins minus monetary losses revealed a gambling response detectable at the single-subject level in the ventral striatum and vmPFC.
