I am wondering about some details, on how to improve the game understanding.

Do you think that using only "bits" instead of BTC, mBTC and uBTC would make all things simpler?

1 bit = 0.000001 bitcoin

so, playing a combo would cost 10 bits, and the typical prizes would be:

3 points 537.02 bits
4 points prize 23897.61 bits
5 points prize 1109744.89 bits
6 points prize 34334139.96 bits

Any input is appreciated!
