Thought this might be of interest to post here with regard to bankroll requirements for these.
Please note: the number of buyins isn't actually a recommendation, but simply the value calculated as per the
Kelly Criterion (ie: don't attempt to play SNGs with a 5% ROI and 38 buyins, etc!!!). The ratio of the increase between the two types of SNGs is of interest though and should be a pretty good guide of roughly how much you would need to scale your existing BR requirements up (or hopefully put you completely off playing these if you expect a very low ROI...).
(X-Post from
Probability &
NVG threads) Here are the results with 4% rake included for each game type, for 1%, 2%, 3%, 4% and 5% ROI players:
So:
1% ROI player needs P(1st) = 0.350694
2% ROI player needs P(1st) = 0.354167
3% ROI player needs P(1st) = 0.357639
4% ROI player needs P(1st) = 0.361111
5% ROI player needs P(1st) = 0.364583
1% ROI player's optimal bankroll fraction for 3-handed "winner take all" SNG = 0.0053185 (~188 buyins)
2% ROI player's optimal bankroll fraction for 3-handed "winner take all" SNG = 0.0106388 (~94 buyins)
3% ROI player's optimal bankroll fraction for 3-handed "winner take all" SNG = 0.0159576 (~63 buyins)
4% ROI player's optimal bankroll fraction for 3-handed "winner take all" SNG = 0.0212764 (~47 buyins)
5% ROI player's optimal bankroll fraction for 3-handed "winner take all" SNG = 0.0265952 (~38 buyins)
1% ROI player's optimal bankroll fraction for 3-handed "Spin and Go" SNG = 0.00047093 (~2123 buyins)
2% ROI player's optimal bankroll fraction for 3-handed "Spin and Go" SNG = 0.00140016 (~714 buyins)
3% ROI player's optimal bankroll fraction for 3-handed "Spin and Go" SNG = 0.00302398 (~331 buyins)
4% ROI player's optimal bankroll fraction for 3-handed "Spin and Go" SNG = 0.00533822 (~187 buyins)
5% ROI player's optimal bankroll fraction for 3-handed "Spin and Go" SNG = 0.00816306 (~123 buyins)
1% ROI player's optimal bankroll fraction increase ratio = 0.0053185/0.00047093 = ~11.3x
2% ROI player's optimal bankroll fraction increase ratio = 0.0106388/0.00140016 = ~7.6x
3% ROI player's optimal bankroll fraction increase ratio = 0.0159576/0.00302398 = ~5.3x
4% ROI player's optimal bankroll fraction increase ratio = 0.0212764/0.00533822 = ~4.0x
5% ROI player's optimal bankroll fraction increase ratio = 0.0265952/0.00816306 = ~3.3x
I'll see if I can re-do this with the top 3 prize-levels split 80/10/10 tomorrow (got killer backache from sitting infront of computer today and off to chill for a bit now...).
