Field notes
The analyzer accepts pasted encoded text, displays A-to-Z letter frequencies, and can suggest a cipher and key when it finds one. The Morse course uses audio-first practice, with controls for lesson speed, tone, and replay; the page cautions that its dot-and-dash chart is for lookup rather than learning. Other listed activities include printable code puzzles, Code Hangman, Sokoban, and a clock-tower gears game.
