Wow this "40,000x line bet" rule is interesting... if you had been betting $2 on one line you could have potentially made $80,000! This means that on a slot with this limitation (and no bonus for max bet) the E.V. would always be best if you were only playing one line, no? On top of this the random jackpots payout to any size bet randomly, so the best bet on all RTG slots is 1 cent on 1 line! Zoozie help me out here...
I'm sure Zoozie will jump in here soon but in the meantime, here's my input:
If you are only playing one payline, you are seriously limiting your chances of winning anything other than scatter wins. You would probably never even come close to reaching the 40,000x limit if you did this.
Let's assume a $2 bet on payline #1 only, and try for the best possible scenario:
During your regular spins, you hit 5 scatters (we'll assume that at least one of the scatter symbols was a wild symbol, so that the prize is doubled). That's 200 x $2 = $400 to start. The reels respin and pay again, so that's another $400 = $800. And now you have 100 free spins with a 5x multiplier.
My own personal experience with this game is a far, far ways away from what RobWin experienced last night. I have found this game to be similar to Isis - very tight most of the time, but with enormous potential during the feature. I mention this here because I have played hundreds of consecutive spins at this game without getting 3 scatters, and right now you only have 100 spins to try to do so.
During your free spins, every time you get 3 or more scatters you receive an additional amount of free spins equal to the number of free spins you started with, in this case 100 free spins.
Here is what you would get for each possible scatter win:
2 scatters, no wild = $10
2 scatters, w/ wild = $20
3 scatters, no wild = $20 plus another 100 free spins
3 scatters, w/ wild = $40 plus another 100 free spins
4 scatters, no wild = $100 plus another 100 free spins
4 scatters, w/ wild = $200 plus another 100 free spins
5 scatters, no wild = $1,000 plus another 100 free spins
5 scatters, w/ wild = $2,000 plus another 100 free spins
Since you started out with $800 worth of wins from the trigger, you would need to accumulate another $79,200 to reach the cap. Getting close to that would be impossible with 2-scatter wins. You would need to hit 3 scatters 1,980 times (with wild) or 3,960 times (without wild); 4 scatters 396 times (with wild) or 792 times (without wild); or 5 scatters approximately 40 times (with wild) or approximately 80 times (without wild).
The best thing you could hope for is to get 5 of the teepee symbols (the highest paying symbol) lined up on the payline, where one of them is the wild symbol. This pays 5000x your line bet, which would take care of $50,000 of your $79,200 quota. Then you would be left with $29,200 worth of winnings to accumulate.
My opinion is that, while it would not be impossible to reach the 40K cap by playing just one payline, it would probably be very difficult and unlikely.
But then again, I would have said the same exact thing about RobWin's session before he started this thread...
