In the memo write a whole number between 5 and 85 for your desired chance to win.
Max Payout is 8 SBD!
MAX PAYOUT IS 8 SBD so don't bet 4 SBD with less than 50% chance to win. You'll be paid 8 SBD.
In about 1 min "refresh" the page to see the result.
Every losing bet will receive .001 SBD so you can see the transaction id.
NOTE: Rarely the transaction id won't line up. This is do the the way I request it. get_account_history steemrollers -1 1 I will work on this bug when I have more time. It happens when there are many requests at the same time. The code plays off the number I send back in the memo. Thanks Hive account@deeprocks for pointing this out. UpVote him :)
Fairness
House edge is 2%. We add (255 *.02) to your roll.
To get your roll number take the first two characters in your transaction id and convert them to decimal value. You can do that with this site.
*Payouts are as such because the house edge is added to the roll. Meaning 50% is really 48%.
** This is an automatic process. Please check to make sure there are funds available. I started it out with 80 SBD.
*** Leave feedback is steemit.chat #steemrollers channel. I will be happy to correct mistakes.
**** House edge will diminish and limits will be lifted as the wallet grows!
