Although most[5] of its source code is available, Prime95 is not free and open-source software because its end-user license agreement[3] states that if the software is used to find a prime qualifying for a bounty offered by the Electronic Frontier Foundation,[6] then that bounty will be claimed and distributed by GIMPS.
