This game is free and ... well ... you get what you pay for.
The object of the game is simple, as described by the title, but the real fun comes from trying to figure out all of the achievements. Enjoy!

I’ve been pretty critical of robust (non-browser) PC games for a while now. I like the comfort of putting a disc in my console and knowing that it’s just going to work the way it’s supposed to, at maximum capacity – no tinkering with settings to get it work with my video card, no shenanigans to get the sound to work right. But when EA came out with a free game right around the time I got a new laptop, an apostle convinced me to give it a go.
I've been doing a lot of newspaper puzzles lately. With them, I've started trying the Cryptoquote and Cryptoquip. Yesterday, I ran across this online game, emulating these puzzles in a flash window. It's totally free and doesn't even require you to sign up or download any software. At first it seems hard, but they're very do-able in just a few minutes.

Tips:
Start by determining vowels.
Look for 1 or 2 letter words, then guess the likely vowels in these words.
