04/26/13: UPDATE - answer and winner revealed on page 33. Welcome back to the games message board! If you're joining us for the first time, we're running a contest in tandem with our brain health sweeps for all you gamers who love a good brain teaser now and then. Go here to see past challenge questions marked with a sticky post. Here's how this works: Each Monday until the sweeps ends, I'll post a brain teaser in this forum and you will give an answer in a reply post. We'll collect responses all week until midnight Thursday; on Friday the answer will be revealed and a $20 gift card will be awarded at random. A person is eligible to win whether they answer correctly or not. The sweeps is ending soon so this is our second to last challenge question. Don't miss out on the fun, play now! Look at the drawing below. Which square is darker, square A or square B? (Tip: click to view a larger image.) credit: Posit ScienceWant to play more brain games?
