"Sudoku" is a number puzzle game that has become very popular in recent years. The game above includes thousands of puzzles, from easy to super hard. The controls are below the puzzle. Enjoy!

Instructions. The goal is to fill the 9×9 grid so that each column, each row, and each of the nine 3×3 boxes (also called blocks or regions) contains the digits from 1 to 9, only one time each. The puzzle setter automatically displays a partially completed grid.
Click the black down arrow to select the difficulty of the game. You can pick "very easy", "easy", "medium", "hard", "very hard". Now you're ready to play! Click the right arrow if you want to load a new game. Click the round gear button to show the solution. Clicking the small clock pauses the game, and if you want to see all the instructions, simply click the question mark button. Have fun!
I have a hand-held game that I play nearly every day. The one I have has a touch-pad screen and great features like back-lighting and the ability to make notes.
The hand-helds are inexpensive and can be found at many drug stores, at Wal-Mart, or online. The hand-held game at left, for example, has all the top features and only costs about $20.
There is no question that playing this math game improves your focus and concentration.
Advanced Brain Training
I complete a quick, 10-minute Lumosity brain training session every morning. These training sessions exercise the different areas of my brain and prepare my mind for the day ahead. Over time, these sessions have sharpened my memory and other mental abilities in a significant and noticeable way. A Lumosity brain training "session" consists of several mind-expanding brain games designed by the scientists at Lumosity and automatically selected for my individualized training program. Examples include Birdwatching, Monster Garden, Lost in Migration, and Spatial Speed Match, just to name a few. Scientific studies show that Lumosity brain training measurably improves memory, attention, cognitive control, and processing speed. To help me track my own improvement, the "My History" section of Lumosity charts my brain's capabilities over time with easy-to-read graphs and Brain Performance Index (BPI) scores. Lumosity is free to try. Complete one brain training session a day for two weeks, and I guarantee you'll be hooked! Note - If you need help with Lumosity or have questions, feel free to send me an email through the Contact Me page at left. |
