Mastermind RK is a little cross-platform game for various classic Z80-based computers, written in C using the z88dk compiler (www.z88dk.org).

Your goal is to break a four-digit colour code in as few moves as possible.

The compiled program is a little over 8K in size, so it usually requires the target machine to have at least 16K RAM.

Currently, 82 target systems are supported, including Mattel Aquarius, Sinclair ZX80 and ZX81 (with a separate Chroma colour version), ColecoVision, various Robotron computers, Philips P2000 and VG5000, and many more.
