So I was doing some experiments with Hive signatures to obtain truly random values. So I created a slot machine(https://games.hivetasks.com) that works with an easy to understand formula:

1. Bot detects an HBD value transacted to @htgames with slotmachine in the memo.
2. Take last byte from <transaction block>+1, divide by 65 and get remainder R.
3. Take remainder R and get value at that byte position in the signature of following block(<transaction block>+2).
4. Repeat steps 2 and 3 two more times, replacing the <transaction block>+1 with the first block following the last number.

Well, this is just an experiment I was doing lately. I also have a bot running to detect winning transactions and send 8K times the transacted bet to the winner(or @htgames balance if not enough available HBD).

Well... this is just an experiment. feel free to play if you want.
