This Flash game was resurrected by Ruffle. We are using Ruffle to emulate our old Flash games, allowing you to play them once again without Flash player. It doesn't work for every game yet, but we hope to bring back more and more Flash content as Ruffle is further developed. Play Karate Challenge unblocked. This game requires a mouse or keyboard to play, so it is not compatible with touchscreen only devices. This game runs directly in your browser - no downloads, no registration, no flash and no plugins are needed to play.
