What kind of puzzles do you like to do to keep your brain active?

Mahjongg Dark Dimensions, Daily Solitaire and my new favorite LUMENO.

I love crossword puzzles and also enjoy solitaire.

I like crosswords and hiddens items pictures.  I also like jigsaw puzzles.

There's an app called CodyCross...GREAT word game...added bonus is the relaxing backround music. Set it on difficult for an added challenge.

Crossword .

Word puzzles. Geography 

Word search. Word Games. Jigsaw Puzzles

I think the current AARP puzzles offering is a pretty good mix. I regularly play: Mahjong Remix (and occasionally some of the other solitaire versions), CodeWord and Bridge.  Also enjoy an occasional game of Word Wipe, 10x10 (when I have time, it can take a while), Pool (8- and 9-Ball both), and Backgammon. Enjoy playing on-line Bridge and Chess but have to honestly say I don't care too much for either of the current versions AARP is using. Would like to see Scrabble and Logic-Art (see most issues of Games Magazine) added to the AARP site because I trust their site security more than some of the sites I find elsewhere on the Internet.

Each evening I start with a hard to very hard crossword puzzle, then play a few hands of online bridge.  After that, I enjoy a difficult word search and finish with several games of mahjong solitaire.

Anything that has to do with words and mystery whodunnits. Also art games especially that deal with colors.
