Numiner started off as a spin the wheel sort of thing for ADF Swaps.
but now mining also produces Numes
Numiner takes the last 6 digits of a tx and tries to match them in the blockID of the block mining the TX
match 3-6 and you mine a nume (mini, mid, big, full. plus you get big coin rewards)
you can trade your numes
combine 4 matching numes to create a numestone and take 50% of the numestone fund (more details in the wiki)

mining has two Tiers, solo and share, 
solo is big dog, share is aimed at smaller miners
solo takes 51%
share take 7 x 7% (49%)

BUT now, the share miners also receive a nume if they match digits like in numiner, only difference is a share miner uses their NID (acct) for their numiner ticket, but they do not get the coin rewards like in numiner (pays out millions) share miners mine for numes and a small amount of coin, they can then trade their numes and form a numestone to take 50% of numestone fund

We now have a treasury that can bump up some funds
plus certain fees get paid into certain funds

so 8 rewards paid every block

and for new accounts we also have RAM mining in the wallet, as new accounts need to receive coins to be onboarded, and then also need set ID type and alias to create neurons in the hypergraph
