Donkey Kong spawned a number of other games with a mix of running, jumping, and vertical traversal, a novel genre that did not match the style of games that came before it, leaving journalists and writers to offer their own terms.[9] Computer and Video Games magazine, among others, referred to the genre as "Donkey Kong-type" or "Kong-style" games.[9][10] "Climbing games" was used in Steve Bloom's 1982 book Video Invaders and 1983 magazines Electronic Games (US) and TV Gamer (UK).[11][12][13] Bloom defined "climbing games" as titles where the player "must climb from the bottom of the screen to the top while avoiding and/or destroying the obstacles and foes you invariably meet along the way." Under this definition, he listed Space Panic (1980), Donkey Kong, and Frogger (1981) as climbing games.[11]
