Regarded as one of the earliest genre of flash games, platform game-play revolves around players jumping onto platforms, stairs, floors, ledges and other objects illustrated on single screen or a scrolling screen. They are readily available online for free play. This genre is said to have been influenced by all time favorites such as Space Panic and Mario Bros. The single screen type involves dodging and jumping objects and focusing on completing a specific objective. Perhaps the best example of the platform category is Donkey Kong. While in vertical or horizontal screenplay the screen moves as the players move forward.
