Quote:rsactuaryHere's a video that shows how the game plays with a bonus triggered at about 4:10:

As Babs mentioned, there are two types of bonuses: 1) the free spins bonus, where three scattered symbols (flags in the first game of this video) gets you 6 free spins. and 2) the "hold and spin" feature which is really the subject of my question.

As part of the normal game, the "orbs" or fireball symbols with numbers on them are just blockers.. until you get at least 6 of them, at which time it triggers the hold and spin feature and you're going to win the amounts listed on the coins (if betting $$, you win the amounts shown, if betting under dollars, it shows the number of coins you will win).

Babs: Saturday night after leaving the GN, I hit a Grand at the El Cortez for $12,700!

What I'm really looking for is based on the simple game that I proposed, what is the average number of games it would take for the jackpot to hit. I'm trying to put some sort of range around how big the "hard" reel is.

Wow! Nice hit, rsactuary! You're the first I've heard of to ever fill the screen. I wasn't sure if it was a come-on that never happened.

Quote:Wizard2. What are the basic rules of this bonus?

3. What is the question being asked about it?

For the purposes of the question, the game rules are thus:

1. Game has 9 positions on a slot machine (or 9 dice, it does not matter; objective is the same)

2. Game is won by achieving a star symbol in each position.

3. Each position has its own probability of awarding star symbol, from 1/3 to 1/10000 (see original post for numbers).

4. Star symbols awarded during game are held during remaining spins.

5. Player gets three initial spins; if one or more winning symbols are awarded on any spin, spins remaining count resets to three.

6. Game ends when player achieves all 9 star symbols or runs out of spins.

Under these rules, what is the probability of winning the game? I guess the other question would be what is the average number of symbols a player would expect to receive during the game.

1. It's 15 spots of which *at least* 6 are filled from the winning spin.. leaving at most 9 open spots.

Please note that my example I listed in the OP is a theoretical one and does not indicate actual probabilities.

Quote:prozemaAgain, just a guess but I suspect the way this feature really works is that the probably of catch a lock symbol gets lower based on the number of locked symbols. E.g. all open spots have the same probably but that changes each time a symbol locks.

I don't believe that to be the case. If you watch the videos in my OP, I point out that the difficult to hit reel is always there. I think they move the reels around between spins to give that impression.

I suspect between denomination levels there is some difference; as the higher the denomination, usually the higher the return. Within a denomination, when betting the number of coins, I would guess that the hard reel (and maybe the others as well??) the length would be some how related to amount bet.

So.. and I'm totally making this up... if you're betting $10 on a $1 denom machine, the hard reel is about 1 in 5000 to hit. if you're betting $5 on a $1 denom machine, the hard reel is about 1 in 10000 to hit. That would be the only way you could come close to making sure the RTP is about constant. (of course they could have the EV of the feature be the same, and just make it harder to hit).
