Cyphr

Cyphr is a word puzzle built on a simple substitution code. Each day the game picks seven words and stacks them in a pyramid, starting with one tile at the top. Every letter is shown as a number, and the same number always stands for the same letter across the whole pyramid, so cracking a letter in one word helps you everywhere else.

You work from the top down. Guess the letter for a tile; if you are right it turns green and keeps its number in the corner as a reminder. A word must be finished before the next row unlocks, but inside a word you can solve the letters in any order. The words are picked at random and do not form a sentence, so there is no phrase to lean on, only the shapes of words and the letters you have already found. You can make up to 26 wrong guesses in all. Hard mode removes the number reminders as you go, so you have to remember the code yourself.

The pyramid, the words and the number code all change at midnight, and everyone plays the same puzzle that day. There is a practice round for learning the rules, statistics, a shareable score and a setting to turn off the bright animations. It suits players who enjoy cryptograms and codewords and want a short one each day.
