Jay Bacal has created an iPad/iPhone/iPod touch app that requires players to think quickly and match common words.
Chain of Thought is a free association word chain game A player starts with a lead word and must build on that word until five additional words, from the list provided, have been properly matched. As an example, if the lead word is churn, the next word might be butter, and the following might be fly. To make it more challenging, each puzzle has two words to match.
The game is free. It is found in the iTunes App Store in the games category. It’s currently in version 1.0 and was released June 25, 2012. It is in English only, requires iOS 4.0 or later and is compatible with iPhone, iPod touch, and iPad. Additional in-app puzzles are available at US$0.99.
Players may play as a solo player, two players, or against on-line opponents. Players also have a choice between difficulty levels of easy, medium, or hard.
