This is a webapp where you can attempt to mine a bitcoin block and put the block reward directly in a bitcoin address of your choice. Your browser will try to find a block whose hash is below a certain target. The difficulty setting will be low at first, but you can increase it til it matches that of the real bitcoin network. Raising the difficulty will take increasingly more work and, probably, more time. You can also mine on regtest.
