Sudoku is a logic-based puzzle that involves filling a nine-by-nine grid with numbers. Each column, row, and square can only contain one of the numbers 1 through 9. The game is popular among adults and seniors because it improves concentration and logical thinking skills. It also reduces stress and anxiety by forcing players to focus on the task rather than an ongoing problem or stressful situation.

When you first start playing Sudoku, keeping notes as you play is a good idea. This will help you remember the best strategies for you and apply them to future games. As you progress, you’ll find that your memory improves, and you can use the same strategies without referring to notes or tutorials.

The key to solving Sudoku is to look for patterns in the grid. For example, if a box has all the single digits filled in or a row has six of the eight digits done, this is a good indication that the remaining number can go into the remaining boxes or rows. This will speed up your solution time.

Another helpful strategy is to find “bent naked subsets,” which are groups of cells with only one value left to be filled. The Sudoku Assistant software program will scout for these bent naked subsets, though you can also look for them by scanning the grid and seeing if there’s a group of cells with only one option left for each number.


Jigsaws are a popular pastime among adults and children. They provide the benefits of boosting concentration and focus, building fine motor skills, and stimulating cognitive processes.

Crosswords are classic games that can be as easy or as hard as you like, depending on your knowledge and memory. You can find them in newspapers, online, or in apps. Some have themes, such as a weekly theme of easy puzzles (Monday or Tuesday), medium-difficulty puzzles (Wednesday or Saturday), and difficult ones (Sunday).

Solving crosswords engages your short-term working memory and long-term permanent recollections. The idiosyncratic logic of each clue-and-answer pairing forces you to make fresh connections. Completing a puzzle can increase your vocabulary and improve spelling and processing speed.

The challenge of solving a crossword also strengthens your emotional control and stress tolerance. This is especially beneficial for people at risk of Alzheimer’s or dementia. In one study, participants who regularly completed crosswords had a slower shrinkage rate in the hippocampus and cortex.

Another crossword variation is a cipher puzzle, which uses numbers instead of letters. Each grid cell has an integer from 1 to 26 printed in the corner. The entries are jumbled, and the solver must identify which number corresponds to each alphabet letter. Some crosswords have clues based on a particular topic or era, such as art, movies, food, books, technology, sports, or TV shows.
