『Brain Games for Adults』 was greatly loved by readers for containing various puzzle types such as mazes, word searches, find-the-difference pictures, and nonograms in one book, and immediately rose to the top of the bestseller list in its category.
Thanks to this support, I was able to publish my second book, Brain Play Book Plus for Adults.

On the plus side, word puzzles and word searches that were difficult to read due to small text are displayed in large size on one page, making them easier to solve.
All puzzles are simple to solve, so anyone can enjoy them.
Connect the numbers in order to create fun shapes, challenging 30x30 squares and Sudoku, find the difference puzzles that require careful attention to detail, and even coloring pages to take a break.
Solve 100 brain teasers and feel both fun and a sense of accomplishment.
