The rules are very simple:
- Transfer 1 STEEM to @fasl's account to buy a lottery ticket*.
- Every six hours a winner is chosen and will receive 97.5%-100%** of the @fasl's account balance.***
Have fun!
* One ticket per round per account. Ticket price is 1 STEEM.
** Refund in case of only one participant is 100%
*** 2.5% is transfered to @%s's and @murh's accounts for the R&D and bot's maintenance.
IF POSSIBLE, PLEASE UPVOTE AND RESTEEM.

It's "free" to use - I've added a 0.25 % licence fee in the code which will be automatically transfered to my account.
The code is compatible with the newest piston-lib 0.5.2 library and nodes.
Have fun! ;)
