Hexar.io is a great .io game in which you control a colored circle and need to capture as many hexagon blocks as possible. Its gameplay is similar to that of Paper.io, another amazing casual multiplayer game. To capture blocks, connect your trail from non-owned blocks to your owned ones. Be careful when leaving a trail because if an enemy hits you, it is a game over. Start building up your domain little by little to help your maneuver. When you see other players leaving too far away from their area, take your chance to hit them! Avoid hitting the opponent's head because you can get killed. Collect green circles to boost your speed. Have fun!
