I just bet 1 btc on this one:

less than 16000    1BTCDiceVit4ZoX62ksdLCbD3fsUww1hX6       24.4141%    4.064x    1.650%    98.35%    0.0010    50.0000    203.0000

which states it has a multiplier of 4.064x ..

and I only got back 3.996444 btc ...

if i do my calculations  1 x 4.064 = 4.064 - 0.0005 (txfee) = 4.0635  ..

is my math wrong?

Minus the house percent.

I thought the house percent already included in the multiplier?  can you explain the real calculation behind the payout?

seeing a 98.35% payout, I thought BTCDice had better payout than SatoshiDice ..
but the same bet at satoshidice:  1btc at the less than 16000 (24.4141%)  gave me 4.00219600 (which is 4.002696 - 0.0005 fee)
so SatoshiDice is actually giving me the multiplier displayed in the table minus txfee
see this one:

yet on BTCDice this is what i got:
http://btcdice.com/details.html?q=38368

Multiplier is calculated by (65536 / Game Lessthan). Previously, that number was rounded down then truncated after 3rd digit, but now it is either rounded up before truncate, or simply truncated.

I take house percentage after multiplier is calculated as doing it other ways (ex. as part of multiplier) are inconsistent in results. Edit: To make clearer, it makes results inconsistent from game to game, or with largely different bet amount, and not always in favor of user.

Satoshidice shows multiplier less the house percent. I show multiplier prior to house percent.

I don't run satoshidice so I can't say how they do their backend maths, but I know payout (housecut, etc) is not consistent from game to game on their site.

Mine is: ((Bet * Multiplier) * (.9835)) - 0.0005
