Secret Postcard
Secret Postcard is a cryptogram puzzle that plays in the browser on phones, tablets and computers, for one player. It has a daily challenge, the same for everyone that day.
Crack a letter-swap code where every letter is a picture symbol to read a cheerful postcard from far away. Choose a symbol, give it a letter and every copy fills in; three or more letters are given to start, and each card can be read only one way. Follow Bea's 48-card route through eight invented places into an album, or decode a new postcard every day.
How to play
- Tap a symbol on the card to choose it
- Now type the letter it stands for, or click it below. Every copy fills inOn a touch screen: Now tap the letter it stands for. Every copy fills in
- Grey letters were given. Short words help: a lone symbol is often A or I
The game shows these steps as you play, the first time.
Controls
- Tap a symbol, then a letter, or type the letter
- Arrow keys move between symbols
- Backspace clears
- Hint fills one symbol
Tips
- A symbol standing alone is almost always A or I, and a three-symbol word that turns up twice is often THE or AND.
- Each hint fills one symbol with its right letter but costs a stamp; a card pays 3 stamps without hints and never fewer than 1.
- When every symbol has a letter the game counts the wrong ones without naming them, so change your least certain guess first.
How do I know a postcard can be solved?
Every card is checked against the game's own list of about 1,000 words: with the letters given at the start, there is exactly one way to turn every coded word into a real word. At least half of the different letters on a card always stay hidden.
What is the album?
Each route card you decode stamps Bea's album, a map of her journey through eight invented places from Pebbleport to Starwatch Point. Open Album during play to see each place's picture, its stamps out of six and every card you have read so far.
