Strategy guies (攻略本 in Japanese, literally "capture book") are instruction books that contain hints or complete solutions to specific video games. The line between strategy guide and walkthrough is somewhat blurry, with the former often containing or being written around the latter. They are often published in print, both in book form and articles within video game magazines. The strategy guide books or booklets are typically sold through game retailers. In cases of exceptionally popular game titles, they are sold through more mainstream publication channels, such as bookstores or even newsstands.
