I like to use puzzles as a way to sharpen my mind. Do you have a favorite type of puzzle?
I do too.  My favorites are crossword puzzles and logic-type puzzles, like Tetris.  What about you?
I like doing word puzzles and Sudoku mostly
Some of the Sudoku puzzles are hard, the 9x9 grid ones, but they are fun to do.
I like doing crossword puzzles too. But I can only do the easy ones. I don't have patience for the ones that take hours.
The New York Times Crossward intentionally increases the difficulty of the puzzle through the week. I get stuck on Wednesdays!
In our paper we have a "daily commuter" puzzle that usually takes 30 minutes or so to do. I prefer that one because I know I can do it and it won't take me all day.
Wheel of Fortune (American game show)
Wheel of Fortune (often known simply as Wheel) is an American television game show created by Merv Griffin that debuted in 1975. The show features a competition in which contestants solve word puzzles, similar to those used in Hangman, to win cash and prizes determined by spinning a giant carnival wheel.
"Wheel" originally aired as a daytime series on NBC from January 6, 1975, to June 30, 1989. After some changes were made to its format, the
been commercialized as board games ("Scrabble", for instance, is based on the idea of a crossword puzzle, and tic-tac-toe sets with a boxed grid and pieces are available commercially). These games vary widely, from games centering on a design being drawn such as "Pictionary" and "connect-the-dots" games like sprouts, to letter and word games such as "Boggle" and "Scattergories", to solitaire and logic puzzle games such as Sudoku and crossword puzzles.
