I fried me old noggin with this thing i found online(where else lol)
It's called lumosity and it's free for a couple(5 i think) of days. You need to register, then it has all sorts of puzzles that are designed to test your all round brain power, memory, attention and focus etc.
I think it's great and perhaps some PCR members might too.
Give it a go, ya never know.....you might enjoy yourself.
