Also; ours allows for multiple staged pre-rolls.
So roll 20 pre-rolls at 0.00000100 - then on bet 21 run 1 increase of 10x (making bet 21x 0.00001000) - then increase on loss 0.0112575 - which is good for Martingaling 99x or 100x strategies into the 1000s of rolls.
Sorry but i have no idea what did you mean by this
"pre-rolling" is where you bet a small (or zero) amount over and over until you lose N times in a row before starting your Martingale sequence in the mistaken belief that the N losing rolls uses up most of your losing streak such that you won't lose too many more times before the streak ends.
Of course in reality the only way the pre-rolling actually helps is that it reduces your average bet size and so reduces the rate at which you lose money.
I guess the spreadsheet is calculating the expected number of pre-rolls required to generate N losses in a row, calculating the expected cost of making all those bets, and adding that loss to the various possible profits and losses from your Martingale streak.
That is correct. The spreadsheet allows you to set a pre-roll wager amount A; and set the number of pre-rolls at A; after which (Using Sharkbot); a one time only Increase on Loss is applied to the first bet of the martingale sequence; then a standard multiplier (Increase on Loss) will be applied to each loss moving forward.
An example would be:
Payout: 3X
Initial Bet Size: 0.00001000
Pre-Rolls @ 0.00001000 = 6
Initial One Time Multiplier: 300% (Which would be applied to the 7th Wager)
Standard Multiplier: 25% (Increase on Loss for Martingale on loss 8-> forward.
It is simply a strategy... like many out there.
I agree with Dooglus; and it is important that players remember that each and every roll is independent in and of itself. Just because you rolled 20 Reds/Losses on 2X - makes it no more or less likely that the 21st roll will win. Past rolls have no effect on the current roll.
However; there is something to be said for the statistical odds of a given loss streak within a series of rolls. Thus; and I am sure Dooglus would agree - that with a Payout Multiplier of 2X - 100 Reds/Losses (Consecutive) would be astronimically unlikely even over a series of millions, or billions of rolls. (I don't think it's ever occurred nor anywhere near that number).
So a player could set up an initial wager amount - for the first 10 rolls; then increase his wager (say triple) on the 11th, and martingale moving forward.
If a player is playing within a legitamate provably fair environment - this would allow longer loss streaks given a specific bankroll. But again; it does not reduce or eliminate house odds or the -EV playing field.
