The holiday break is nigh, which means you need to be careful not to catch a cold.

For many people, the time preceding a holiday, vacation, or spring break is busy — finishing up a term paper, completing holiday shopping, or getting things off your desk so you can enjoy your trip to Tahiti. During that time, your immunity kicks into high gear. It helps to fend off germs while you’re pushing yourself to get stuff done. When your break finally comes, though, you relax, and your body thinks, “Oh, cool, the stress is over.” And BAM! No more immunity, and your body succumbs to infection. Sniffles, headache, and a cough ensue.

How can you prevent this?

Easy. **Do puzzles.**

That’s right. You can trick your body into thinking that you’re still stressed by doing crosswords, sudoku, nurikabe, battleship, nonogrids, or whatever you like. Your mind is working hard, so your body keeps your immunity up. Doing something you enjoy fends off disease. Win-win.

Well, MJ4MF is here to help. The following **SudoClue** puzzle will provide a half-hour of much-needed stress. The idea is rather simple. Use the clues to fill in the corresponding squares of the 6 × 6 grid, then fill in the remaining squares like a sudoku puzzle.

The puzzle below, as well as an easier version, are available in PDF format.
