There’s no reason that keeping your wits sharp has to be a complete drag. Magmic’s BrainUp and BrainUp: Clash of the Sexes both offer a variety of fun, fast-paced puzzles to test a variety of thinking styles, from memory to shape recognition to word manipulation to simple math. IQ Academy also offers the same kinds of challenges in a multiple-choice format. If you’re more the wordy type, Bookworm might be your bag, but Sudoku could just as easily work that problem-solving muscle.
