The book test legend is back!

Somewhere in this book, a spectator chooses a noun completely at their own discretion and concentrates on it. You first receive individual letters. You name them, and the spectator confirms each one. Finally, you name the exact word the spectator actually thought of! The spectator also confirms the correctness, if they are still able to.

Many describe the principle as ingenious. It's completely different from the one used in GMOAB, and these book tests can even be combined. "S-370" is the further development of the "S-270," which is highly regarded by book test experts. New features include the book's title, an improved system, and the fact that you no longer have to pay attention to whether a word is chosen from a right or left page.
