Zap! is a single-player arcade game in which players control a character that moves vertically to avoid white rectangles, aiming to achieve the highest possible score. In this game, the player navigates through a series of white rectangles that appear in rapid succession, with the challenge being to dodge them by pressing space to move up or down. It stands out with its simple yet addictive gameplay, inspired by the wave game mode from Geometry Dash, and is available on multiple platforms including PC, Windows, Macintosh, and Handheld Electronic LCD devices.
