This research examined how jackpots, large EGM prizes that pay out infrequently, influence the behaviour of EGM gamblers. The study also examined the effect of jackpot expiry on EGM gambling behaviour. Jackpot expiry refers to where a jackpot is no longer available after a fixed period of time or number of spins. This research was undertaken through Central Queensland University and funded by Gambling Research Australia.
The prize amount grows incrementally with every new bet placed
The prize is fixed, and does not increase with each bet
The prize will be payed out after a fixed interval, that is not known to the player
The prize is paid out randomly
The prize amount is hidden from players
The exact combination of symbols that will trigger the jackpot is unknown to the player
The prize can be won on one of several machines, allowing for higher prizes. This type of jackpot may operate within a venue (local area) or over several venues (wide area).
This study involved experiments using a simulated gaming machine and observations of EGM gamblers in venues.
Participants played a simulated gaming machine on a laptop computer, which was programmed to provide a fixed sequence of wins and losses for twenty spins. After this point, all spins would result in a loss.
Participants gambled with real money – the compensation given to them for participating in the study.
The simulation part of the study involved four experiments:
Each of the experiments was designed to allow comparisons between the types of jackpots studied. The researchers measured average bet size, speed of betting, total spins played and final payouts.
The researchers also asked about the player's overall enjoyment of the session. In some experiments, the researchers also measured physiological arousal as a result of the gambling.
The researchers followed 234 participants as they gambled in three Queensland gaming venues. The researchers observed machine characteristics, including jackpots available on the machine, and play characteristics. Half of the participants were primed to think about winning a jackpot before the observations.
The experimental component of this research found that:
The observational component of this project found that:
