Hookem.io is free for all Power-ups game with an exclusive concept that is different from other IO games. You play as a character that is armed with a hook, and it’s your job to use the hook for killing the enemies. There are four classes you can switch between, but make sure you earn points so you can spend them on changing the classes. The red one lets you launch a fireball to kill the rivals for 3 seconds. The green one allows you to slice a bunch of rivals at the same time, and you are able to dog underground too. The blue class gives you a speedboost, meaning you can speed up easily to get an edge over the enemies. The purple class is a nice one when it lets you teleport to another part of the map or even detach the hooks attached to you. Your main goal is to climb the leaderboard to rule the arena! Wish you luck!
