Say we are playing some loss Rebate promo in casino. If we deposit 10k
, we got
19% back if we loss all the 10k deposit. Based on computer simulation
result, if we bet 2000$ each time and play until we play hit 4k profit,
or leave when we lose whole 10k deposit to get 1900$ loss rebate, the EV for
this promo playing is about 320$. The chance to leave with 14k(10K deposit
+4k profit) is 70%(p1) , the chance to bust and get 1900$ rebate is 30%(p2).

So we have 10 unit of buyin, what is the ROR for this play? Also, if we
need the ROR below 5%, how many buyin do we need? what about 2% ROR?
Another way to play this is to play until we hit 8k profit which is
optimal EV wise, the chance of winning (leave with 18k) is about 50%(pw),
chance of bust(leaving with 1.9k lost rebate) is also 50%(pl). The EV for
each deposit/play is about 520$. What is the ROR for this play if we have 10
buyin? Also, if we need the ROR below 5%, how many buyin do we need?
thanks a lot in advance!
PS: some risk of ruin caculator
Risk of Ruin = e-2 x WR x BR ÷ (SD x SD)
•e = Constant (2.718281828)
•WR = Win Rate
•SD = Standard Deviation
•BR = Bankroll
