## What is Word Unknown?

Word Unknown takes inspiration from both hangman and mastermind to create an incredibly fun and simple word game experience. Your objective is to guess a randomly generated word in as few moves as possible using both lexical and deductive logic. Once a legal guess is made, you'll get X's and O's in response. Each X represents a correct letter in the correct position, and each O represents a correct letter in the wrong position. There are five different difficulties (word lengths) to choose from and a daily challenge for each so you can compete with friends! Best of all, the game is 100% free and open source! 

Word Unknown is the second word game developed by Christopher Cinq-Mars Jarvis. His first is Synonymy, narrated by Richard Dawkins, which received distinctions at GDC and E3.

### 4/5 — Fun, addictive, with a bug

*2018-11-20, version 3.0*

Way too addictive!
There is a bug preventing one from guessing a proper noun and yet I have gotten stuck in games without end where the word was clearly “Hebrew,” “Muslim,” or “Mormon.”

### 5/5 — Some words ARE unknown

*2018-10-11, version 3.0*

I enjoy the game but have discovered the occasional “buggy” word—my guesses lead to a specific word but the game does not let me enter that word. Two examples are “rape” and “Cuban”. For “rape” I got 4 correct letters for “pear”, “pare”, “reap”, and “aper”; 3 X’s for “rapt” and “tape” but was prevented from entering “rape”.

### 5/5 — Fun😍

*2017-04-10, version 3.0*

Not as good as Synonymy, but still fun for wordophiles like me.

### 5/5 — Elegantly simple.

*2017-04-08, version 3.0*

I can see it having real educational value.

### 5/5 — BRILLIANT

*2017-04-07, version 3.0*

Brilliant experience, can’t get enough…. definitely worth the download.

### 5/5 — Fun and Challenging!

*2016-01-30, version 1.0*

Very fun and makes you use your full vocabulary!
