If this new hash is less than the target, which is basically a 256-bit number specified by bitcoin protocol, then they are done solving the puzzle and get the mining reward. However, if the new hash value is higher than the target value, they have to increase the nonce; that is, increase the nonce from zero to one, and append this one with the hash of the Merkle root, take the hash again to get another completely ...
