Decipher is a browser-based puzzle game that runs instantly, with nothing to install. Think puzzle, word and memory — that is the shape of it. It works the same on desktop, tablet and phone, and your progress picks up where the game left it.
About Decipher
Welcome to the exciting and challenging world of “Decipher,” a game that will test your ability to decode symbols and form words within an 1:30. Prepare for a unique puzzle experience where your mental agility and powers of observation will be put to the test as you venture through increasingly complex challenges. The objective of “Decipher” is simple. The game is divided into two layouts: the first field will display a series of symbols, each associated with a specific letter. In the second field, you’ll find only symbols, with no apparent letters. Your challenge is to use your visual memory and knowledge of letter associations to input the correct letters and form valid words.
How to play Decipher
There is very little to learn before your first run. Load the game above and it fills the player in portrait. On a phone you can play one-handed; on desktop the frame stays centred so nothing is cropped. Restarting is instant, so there is no cost to experimenting.
