What percentage of the overall theoretical payback percentage is contained in the bonus round feature of video slots? While many of the games are entertaining (even for me though my games of choice are poker and certain table games - I really enjoy the spinning streaks games from WMS), I have noticed that since my wife starting playing video slots (exclusively) instead of reel slots, it is nearly impossible to cover her play. In fact, her “donation” to the casinos is usually 2-3 times the amount compared to her pre-video slot days. I am sure this is not an isolated event! I look forward to seeing the numbers……………..

Bonus frequency tends to be about once every 100 to 200 spins. The average win tends to be about 25 to 50 times the bet. The earlier games tended to have more frequent, but smaller, bonuses.

Thanks! That will give me a range to play with. When you stated "earlier games", how many years back were you thinking?

Wizard/MathExtremist/Anyone else! - Regarding your assumption above, and forgetting about small payouts for a moment, if i bet $.25 for 100 to 200 spins I would end up betting $25 to $50 and only win back $6.25 to $12.50. A sure loser.

But how do you translate this with max/multi-line betting? If I bet 5 lines at a time, does this count as 5 of the 100 to 200 "spins" or just one of the 100 to 200 spins?

In other words, if I bet $1.25 (all 5 lines) on a quarter 5-line WOF machine and that counted as 5 spins, then I should hit the bonus wheel after pressing the spin button 20 to 40 times (100/5 to 200/5). That would cost me $25-$50, but at $1.25 a bet my bonus wheel payout would be 25 to 50 times $1.25 -- or $31.25 to $62.50. Seems like I should be making a regular profit under those assumptions, all other payouts aside, correct?

Seems like a huge swing in terms of profitability which i find hard to believe. So the question is: When you bet 5 lines does it only count as one or five of the 100 to 200 spins? The implications seem enormous...

I'm not very familiar with the community bonus Wheel of Fortune. However, the bonus frequency in that game I think is tied to an individual event, like getting both halves of a wheel symbol. I could easily be wrong, but I think that what matters is the speed of play, but not the amount bet per spin. You're rewarded for betting more per spin by getting more when I bonus hits.

(Thanks Wizard)

I was actually referring to just the simple little bonus wheel on top of the non-community WOF games, where you get anywhere from 25 to 1000 credits on the spin. You get to spin that wheel when you get three "Spin" symbols in a row. (I am referring to the machines currently at McCarran by the way).

When you say the "bonus frequency in that game is tied to... " are you referring to Wheel of Fortune games in general, or did you specifically mean community Wheel of Fortune games?

Also, anything behind the speed of play hunch? Are you suggesting that the game recognizes it when you play more rapidly and changes its bonus frequency? In other words, rewards people that bet more per hour?

On all WOF games that I know of, the bonus is triggered by a symbol combination. This includes the community WOF games. The difference on the community games is that players can play the bonus at the same time if they so choose.

On WOF community game, there is nothing behind the speed of play. Obviously, though, if you play more games in an hour, you will get more bonuses in an hour. This is different from other community games in which your rate of play matters because the bonus is a "mystery" trigger, meaning that it is not triggered by a reel combination.

If a bonus is triggered by getting a certain number of symbols on a payline, then the bonus is awarded more frequently as you wager on more lines. In this case, the pay in the bonus is usually scaled by the number of credits wagered on the bonus initiating line. So, wagering 5 lines is a lot like playing 5 games, except they are not independent. Playing 5 games at one line gives you the opportunity to win the bonus 5 times, but wagering 5 lines gives you 5 times the probability of winning the bonus once.

Sometimes, though, a bonus is triggered by "scatter" symbols, which do not need to appear on a payline, just anywhere on the reels. In this case, the bonus frequency remains the same regardless of lines played or bet per line, but the average win in the bonus is scaled according to your total wager.

Some exceptions can be made to the above statements on games that require the player to play all lines, or on Multi-Way type games (those advertised as 243 ways to win).

Thank you CrystalMath! very helpful.

So playing five lines doesn't give you an advantage at all then, other than hoping you hit a big bonus quickly so you can walk away on the good side of Lady Variance?

Correct, you don't generally gain an advantage, but playing more lines makes the game more interesting.

On my favorite game, the bonus frequency is about 1 in 1400 for playing one line. It would be very boring waiting for that bonus. Instead, the manufacturer wants you to have more fun by playing all 15 lines, which makes the bonus frequency more line 1 in 90 games.

Is this new? When I played non-community WoF ($1 machines at Golden Nugget back in 2008, IIRC), I'm pretty sure only the third reel had the Spin symbol on it (you might be confusing it with the Jackpot symbols, which look a lot like the Spin symbol).

(Then again, I am referring to three-reel non-video. For all I know, there's a 5-column video version as well.)

EDIT: I just saw this post about these being five-reelers.

Related question: if you are playing multiple lines and three bonus symbols appear on two or more lines in the same spin, is the bonus multiplied accordingly? If not, you might want to take that into account when calculating expected bonus payouts.

If a bonus is triggered by a line combination, then you must get the bonus for both overlapping lines or have the bonus multiplied by 2. One example is Money Storm. On that game, you get free spins for getting 3 or more Tornadoes on a reel. You get something like 3 spins for 3 Tornadoes, 6 spins for 4 Tornadoes, and 15 spins for 5 Tornadoes. If you initiate the bonus on overlapping lines, it issues the sum of the free games awarded on each line.

I don't know of any WOF games that work like that, but there are many, many, varieties of WOF since it has proven to be the best and most well recognized slot ever.

thanks.
any idea what the frequency of a bonus spin of the wheel is on a simple, progressive quarter Wheel of Fortune machine? (that wheel on top of the machine with 10 to 1000 in credits)

Not sure if this is new as I live in LA and don't frequent Vegas enough. I played a quarter, three reel, five-line, non-community, progressive WOF at the Southwest Terminal at McCarran, waiting for my layover. They were arranged in banks of eight machines.

It DEFINITELY had a Spin symbol and you needed three in a row in any direction to spin the bonus wheel. It ALSO had a Wheel of Fortune symbol to win the progressive jackpot.

May I ask which game is your favorite?

Also, do you know if there is high or low variance with slots? In other words, if i were to put $1000 in a non-progressive slot machine that returned 95% I know it would eventually grind down to zero, but what would the theoretical max swings be on the small play assuming I don't hit the big jackpot. Could I find myself up $500 or $400 or 300 or $200 or $100 along the way before probability took me the other way to a loss...

Not sure if that's clear, I guess I'm just trying to figure out what a good lucky run is with small play, assuming I dont hit the big jackpot...

Is it true that on a multi-line slot machine, say 25 lines, that the payoff for each line is equal? And if you are the big hits on each line equal ? Or is there no standard, just the overall edge ?

Yes, each line has the same odds. There are exceptions for games like Davinci Diamonds, where the top lines get scored more often. Otherwise, the big hits should happen on each line with equal chance.
