Exercise your brain

Here's a way to exercise your brain and maybe win some money.

The Alzheimer's Foundation of America has launched the first National Brain Game Challenge, a competition for adults with a $5,000 grand prize.

The games were created by Merl Reagle, whose Sunday crossword puzzle is syndicated in 50 newspapers across the country.

Registration costs $25 and provides online access to the puzzles on Sept. 25 at 3 p.m. Eastern time. The contest ends Sept. 27, and winners will be announced the next day.

Players must electronically submit solutions to each puzzle plus a final answer. The foundation will determine winners based on accuracy and speed. In addition to the $5,000 grand prize, there will be a $1,000 second prize, a $500 third prize and more than a dozen $100 prizes to other winners, including the 5,000th person with the correct response.
