Hive account@steemdice1 & Hive account@phareism

After reading the very lucrative payout summary for the top 3 users and then seeing that one achieved 75 wins in a row and another close to 50 I believe - I was curious to see what numbers they chose to wager against.

I was sure to see a by ch of lower than 95 for example. However I didn't even get that far. What caught my eye was that Hive account@ardyach was able to place 5 distinctly different wagers all against the same Block - #21717679.

This confused me because if this is allowed someone was Hive account@ardyach not getting against himself? Thus lessening the likelihood of a win or lessening the win potentual?

Every time I had ever played on steemdice.net I was only allowed one bet per Block number and no matter how fast I placed bets the results ALWAYS were compared the a distinct Block result deriving a numbered result.

Would you be so kind to please elaborate on how Hive account@ardyach was able to achieve his betting style and also why some users are able to and others not..

Thanks in advance for the information and much thanks for writing the code for us Steemit users to have a fun outlet to gamble STEEM and SBD if so desired :)
