Synonymy is a non-profit, educational word game narrated by Richard Dawkins that challenges players to find a path between random words through their network of synonyms. By taking the synonym of a word, and then a synonym of that synonym, and so on, you can ultimately arrive at any other word in the English language. Version 3.0 has been rebuilt behind the scenes to make the game easier and more fun without sacrificing the spirit of the game. The lite version now has no external ads, just a pop-up prompt to buy the full version. Website: www.synonymy-game.com ————————————————— Try the game Stephen Fry and Steven Pinker are tweeting about! A lite version of the game with ads and restrictions on multiplayer and difficulty settings. The Full Game supports unrestricted multiplayer, and weekly challenges in which users can compete globally on set start and end words. Every time a path is uncovered by a user, it is tweeted from @synonymywords and posted to our Facebook page. Synonymy is the first game by filmmaker Christopher Cinq-Mars Jarvis and is narrated by world-renowned author and biologist, Richard Dawkins. All profits go to various charitable, education-based foundations. ** Works best using iPhone 5/iPad 2 or later and iOS8 or later. Requires iOS7 or later. The game seems to work on older devices but performance might suffer. Please address any concerns to www.synonymy-game.com/#contact A visualization of the game's network can be seen here -- http://www.gigapan.com/gigapans/159329 -- In order to compute relative distance, all synonyms were mapped using 3d graphing software, as if each word were a planet that had a gravitational pull proportional to its number of relationships to other nodes. Above is a 2D representation of that model, a 40,000 x 40,000 image.

Kill some time and give your brain a little exercise at the same time with this simple game. You start with a random number and then start dividing by single-digit primes (2, 3, 5 or 7). When you can't do any more divisions you 'bump' the number -- multiplying by 10 and adding any single digit. You win the game by reducing the original number to 1.
