Question about slot machine returns

I have been playing some of the must hit by slot machines when the jackpots get to certain levels and I've been working through the math to figure out the +EV spots.

My question and my uncertainty is around the base return of some games (the Ex-jackpot return), which is a key factor in figuring out the cutoff points.

One question I have is whether the base return of the game varies based on the number of credits per spin. For example if a machine can be played at max lines anywhere from 40 cents to 2 dollars, does the base return usually vary or is it just multiplied by 5 as you go to max credits.

This is important because I know what the returns of classes of machines are like penny slots at my local casinos, but it would be really helpful to know how to interpret this information. The difference between an 85% return machine and a 90% return machine can be big for figuring out cutoff points.

I guess I am wondering if a standard slot machine like this is usually programmed to offer different odds depending on the number of credits bet, or whether the additional credits just act as a pure multiplier.

Any help would be appreciated.

Cant really answer the Math involved, but I can tell you about a recent experience I had. Found a machine at mohegan Sun that was at $46, and must hit by $50. At 40C a pop, I went through $100 fairly quickly, and I believe the Meter was at $47.50 when I left. I walked away from the machine fearing investing another $100 to make $50 would be a bad gamble at that point stuck $100 and counting.
Now, players are not dumb ( except maybe me ) ...but I'll play from now on if I find a must-hit mini at $48, or a must-hit major at $480. I know its rare to find anything that high...but...you can get burned by these near jackpot machines.
best...Tom

On the penny machines a lot of times it's just a pure multiplier so you're better off min betting. Also, the more you bet, the less valuable the progressives are since they are usually fixed as well. But in casinos there are always exceptions, usually you get a better percentage return the more you bet, but sometimes it's the same and sometimes it's even less. I guess the even less machines are designed to trap those that bet max when they hit something because normally the casino should be rewarding those that bet more, not penalizing them, but casinos are rarely run in ways that make good business sense. --- In vpFREE@yahoogroups.com, "vpplayer88" <vpplayer88@...> wrote:

The math is really simple if I understand Michey Crimm's post on the Quick Strike machine. This is a new play for to me, so I hope the experienced players will add to or correct this post.

If you find a machine at $46 your average win is $48 and your average cost is $40 if the base return is 80%. This assumes the bonus payout increases at .01 per dollar played (1% movement). 80% payback is the minimum payback allowed in many jurisdictions and the minimum still gives you a 4% edge. If the machine payback is 90% then your average cost is $20 and your edge 14%. There is no way to know the slot machine payback so just be conservative on your cutoff.

There's no technical reason preventing a slot machine's hold to be based on amount of coin-in. There may be rules/regulations or manufacturer resistance to making thing more complicated then need be.

I think the later is important for both the manufacturer and the casino operators. Keep it simple.

The idea casinos would reduce return @ full coin-in to "trap those that bet max when they hit something" is possible; but don't see it in the cards. Would have a hard time explaining to gaming commission why that is in the interest of the industry. If that caught on it would drive the crowd to reduce coin-in.

I'd also would like to know the answer.

Also, understand that all pick-a-square type bonuses are decided at coin drop. Mojo doesn't work. Would like to know the answere to that. Example "quick hits" bonus round.

Just got back from a week in Vegas. We did $30K action/day on VP and another ~$2K on slots. Three $1 Royals and Two 4A/w kicker. Came home ahead $6K. Lost almost $4K at main street station. Played no slots machines at MSS - no need to stay under radar at that joint.

Dave in Boston (with 4" of snow so far this first day back).
