What’s New

Version 2.0.1

Thanks for playing! We really appreciate it.

We fixed a few bugs and fixed up the screenshots.

We also decided to revert the background to the darker color. Just in case you want to play at night. :) Plus it feels more like the original color scheme too.

A Keeper: favorite in my top three word challenges!

Love this game: It makes you dredge up every possible meaning attached to a given word and think of every possible logical connection before you make a move - if you want a perfect score.
However, if you blow a move, you can work as long as it takes to figure it out: great brain exercise!
I love a good word game, and there are few that do not bore me before long, either because they are too easy or because they require me to know words that nobody ever uses except to play games. This one draws from common vocabulary, but makes you pull up the varied, uncommon and colloquial uses of a word.
You just gotta love the English language; it alone could supply great fodder for such a game! Those for whom English is a strong second language but who may still be be tripped up by one of our common words that occupy a quarter page of definitions in the dictionary, this might be a great proficiency builder!
Very enjoyable if you love word games!!!

100%+ satisfied!!

Awesome game!!! It's easy and yet makes, you use some simple logical thinking to associate words like it will give you the word winter, and you look over your given choices and could choose snow, then maybe ball then basket/ trash, talk, mouth, lips, and so on. It's really simple. But you do have to put in a little bit of thought! Honestly this game deserves 5 stars times 5 trillion; it's really an awesome game!! Don't pass up this chance to get it. You'll have fun and it makes you feel good and accomplished when you're done! Unfortunately, I don't know a word with enough feeling, emotion, and power to describe this game. It's a great game for a great vocabulary!!!

Love this Game

I do not ordinarily submit reviews, so that should tell you something. This game is a breath of fresh air. If you love word games, and you want to exercise your brain with word associations, this is the game for you! I just can’t get enough of it, and I will happily pay the $3.99 to open up all of the game packs. Try this one. You won’t regret it!
