CipherForge

Run a spy agency, learning cryptography from Caesar ciphers to RSA basics through narrative-driven missions — crack codes, build ciphers, compete in code-breaking duels, and escape timed puzzle rooms.

Meet your mentor

Every Spark & Anvil app has a friendly mentor character that demonstrates, praises, and patiently scaffolds learning. On-device AI personalizes the mentor's responses to your kid's progress — never connecting to a server, never collecting data.

CipherForge is a spy academy where you learn the real science of secret codes! Run your own spy agency, crack codes from simple Caesar ciphers to tricky modern encryption, compete in code-breaking duels, and escape timed puzzle rooms. Every mission teaches you real cryptography that spies and comput

What's inside

Spy Missions

Each mission has a story where you need to encode or decode secret messages. Start with simple letter-shifting codes and work your way up to complex ciphers. Th

Code-Breaking Arena

Race against the clock to crack coded messages. Use the cipher workbench tools to analyze patterns, count letters, and crack the code before time runs out.

Escape Rooms

Solve a series of cipher puzzles to escape before the timer hits zero. Each room has a theme and gets progressively harder. Use hints if you get stuck -- good s

Cipher Library

Study the history of secret codes, from ancient Rome to modern computers. Each cipher comes with its story and step-by-step instructions.
