Roulette though always sends you a payout by adding 0.000000XX to the payout amount, where XX is the number the ball landed on 0-36.
roulette-red WIN! Result 36 Red Bet 0.16 BTC Payout 0.31950036 BTC
roulette-red LOSE Result 15 Black Bet 0.08 BTC Payout 0.00000015 BTC
For our Jackpot Dice (clone dice v2) we decided to drop the losing payouts in favor of raising the winning multiplier.
Players can optionally pay to have a loss notification by sending their bet in multibet that includes the address for 'Result only'.
'Result only' has the smallest min bet possible that covers sending the result as a micro payout.
