What games do you play to keep your brain healthy?

I solve the Jumble and Cryptoquote daily.  Occasionally, I do the crossword puzzle.  And, I play both Solitaire and Mahjong online.  I play Trivia Crack on my phone.  Occasionally, I play HQ Trivia, but there's too much hipster clowning around, and they're not truthful about the questions being "progressively" harder.  There's three simple questions, then one bizzare question that about half the players get wrong . . . and get eliminated, then there are eight questions of varying difficulty, but by then you're just a spectator.  I also play along while watching Jeopardy and Wheel of Fortune!

I enjoy crossword puzzles as well as online solitaire. I too watch and play along with Jeopardy. Locally in the Washington DC TV viewing area, we have a high school quiz show, "It's Academic" on Saturday mornings which covers literature, history, art, mathematics and sciences. 

I don't get the newspaper every day, but I enjoy doing the Jumble when I do.  Every night before going to bed I play games on my tablet until I'm sleepy.  I play Spades, Hearts, Solitaire, 7 Words and Scrabble against the computer.  I occasionally play Backgammon and Word Search on it, too.  I also bring my tablet to the doctor's office and other appointments to entertain myself while waiting.  I have these games on my smart phone, too, and I play them in restaurants and such while waiting for my friends to join me.  I'm heavily into genealogy research, too.  I research almost daily, and it keeps my mind ticking while searching for those elusive new clues!  : )

In order, the Jumble, Sudoku, and crossword puzzle found in the Philadelphia Inquirer get my neurons moving just after breakfast. And like Rainman, I have to watch Jeopardy every weekday evening.

I do a lot of crossord puzzles and play Free Cell and Spider Solitaire.

I'm surprised that I haven't read chess in any of these replies.  Other than Go, there isn't any game more stimulating than chess.  I've been playing off and on since I was 15. I commute to NYC daily and it provides me with a way to pass the time on the train as I play against the app on my phone.

My favorite games are Scrabble, Solitaire, Chess, & Cribbage.

I enjoyed reading the responses... you all have given me some new ideas!

Variety keeps me more mentally on target. I play Sudoku, Scrabble Sprint, and Cryptoquotes online  (I highly recommend  this site, they have many onlines games that are all free to play):  https://www.memory-improvement-tips.com/scrabble-online-free.html

I also do crosswords on & off. But my favorite puzzles are the logic puzzles; the publishers sell bundles of puzzles from previous years at a deep discount and it's so much less expensive than a regular subscription (check out PennyDell online).

In addition, I read a lot-- daily-- and craft as well, which works my brain in a different way while my hands are aslo busy. Just started doing paper mosaic pictures, which can be maddening when my cat wants to help, but is a lot of fun!

Since I don't have anyone local to play Scrabble with (my favorite), I play Words with Friends online with my mother (she usually wins), and Boggle on line with her (I usually win).  I also play the Crickler puzzles online every day - also challenging against Mom.

I like the online game site Pogo.  It's free, as long as you don't mind ads, or you can join Club Pogo for a fee & play ad-free.  They have Scrabble, Mahjong, Bingo, Bejeweled, Crosswords, Slots, Hidden objects, Word Whomp, Tumble Bees & so much more.
