A Daily Sudoku Practice Built for Focus and Calm.

"Honestly, I was skeptical about the 'Ultimate' claim, but this book delivers. The grids are huge and easy to write in, and the paper holds up well to my heavy-handed erasing. Excellent variety too."

"I buy these for my husband who is legally blind. The large print is actually large enough for him to see without his magnifier. He loves that he can do them independently again. Thank you!"

"The Jigsaw variants are a total brain bender. I got stuck on puzzle #42 for two days, but the feeling of solving it was unbeatable. Solutions in the back are accurate, which is rare for these books."

"Perfect size for my purse. I take the Pocket Sudoku with me to the DMV and doctor's appointments. It lays flat nicely so I don't have to break the spine to write near the center."
