Prime Miner

Mine for prime numbers: each round costs points, and finding a prime wins from the treasury.

primeminer.xyz · listed 1 Oct

Prime Miner is crypto mining with a twist. Instead of hashing, each mining round tests a number, and miners compete to find primes. A round costs 10 points, and finding a prime wins from the shared XNT treasury and the points pool.

You can automate it: set the number of rounds, pause after a find, or only mine when the treasury is above a level. Points can be swapped, and winnings cashed out. The game's code is open source.
