About Crate Protector GameCrate Protector is a 12-stage Sokoban variation game. Each level contains an X which is inside a blue box which moves around with it. Use the crates to push the X (along with the blue box) so that you can reposition them in such a way that enables you to place a crate atop each of the markers on the ground. Move around the level by pressing the arrow keys. If you make a mistake you can press the R key to restart the level again. In this game, unlike most Sokoban games, you can push two consecutive crates. This is a JavaScript web application which uses cross-platform mobile-friendly HTML.
