Dunbar's got a tool that will give an exact answer, but for that many
hands, using the normal approximation won't be far off:

$250K/$1.25 = 200,000 hands at 5 coin quarters.

1SD = SQRT(Variance x hands) = SQRT(26 x 200,000) = 2,280 bets =
$2,850 at 5 coin quarters.

So:
68% chance of plus or minus $2,850
95% chance of plus or minus %5,700
about a 2.5% chance of losing more than $5,700

The cashback barely covers the negative expectation of NSUD. Assuming
no mistakes in play.
