Fidgetio.com is a nice game like Agario which is totally free to access. In the game, you have to move around the map with your fidget spinner and try to collect a lot of score in order to grow its spinning power. Once you get to a safe amount of spin power, quickly collide with the nearest enemy to destroy them. Watch out for your surroundings and do not let others outsmart you! The goal here is to become number 1 on the leaderboard. Good luck to you!
