Smelter.io is a cool Power-ups IO game opening a battle between players and bots. Once joining, you will start moving around the map until you become hot. Getting hot will let you perform a lot of jumps to destroy the enemies that get in your pathway. You are supposed to prepare your movements carefully so that you can elude the jumping of others. If they have high temperatures, make sure you won’t get close to them. Also, you shouldn’t assault them with a jump either, or else both of you can be demolished. You can kill them by using shock and shot bonuses or a bomb. You shouldn’t forget to pick up stars, or increase your points from killing your rivals. Always remember that if you are at a higher temperature, you are able to make a longer jump. Try to destroy everything and climb your way up the leaderboard. Good luck!
