Other arguments aside, there is one other that is with the player all the way:-
RESPONSIBLE GAMBLING!
In setting the slot to default to $750 per spin every time the game is loaded, regardless of the players' own playing style. Have the casino demonstrated the right attitude to doing it's own part in promoting responsible gambling among players?
This situation is the classic "accident waiting to happen", since the casino has made the player responsible for checking each and every game to ensure that the default is a bet they are happy to make.
The RESPONSIBLE attitude would be to either retain the stake from the last session, or to set a default that the majority of players feel is not too far off their usual bet.
Can the casino argue that the majority of it's players would be comfortable making the odd $750 default bet through forgetting to set up the slot before taking their first spin?
The FIRST section in the standards expected of a CM accredited casino focus on this very topic.
Player and Responsible Gaming Focused
Must forbid underage play.
Must have a clean history of fairness towards their customers.
Must be able to take care of any player issue swiftly and professionally.
Must display information about responsible gambling, with links to relevant organizations.
Must offer and enforce spending limits in addition to both temporary and permanent self exclusion options.
Although there is no specific point dealing with the choosing of software bet defaults, the last one comes close.
Would setting a game to always load with a $750 stake be considered as "OK".
They certainly don't "offer" a service to the player that would protect them from accidental'y making that $750 spin, and they can't "enforce" something they don't offer.
Well, this is Main Street, and they recently lost their accreditation over their attitude to timely payments of player withdrawals. This is yet another move in the wrong direction.
We KNOW that the default bet is something the operator has control over, so this is no accident, they CHOSE to set the default this high for their players.
I have loaded many RTG slots, and the default is usually a max coin and max line bet between $2 and $10. I have not even found it POSSIBLE to push the bet past $125, as this seems to be the RTG default setting.
