ORBz.io is an arena multiplayer game in which you control a player surrounded by three orbs. The orbs will inflict damage on enemies if they come into contact with them; however, the enemies can cause damage to the player via their own orbs.

When starting the game, you will have 100 health points. By moving around the arena, you will be able to pick up figures spread across the map, which will give you extra health points. When you grow up, your body and orbs will get bigger, so you will get more power.
You will be able to regulate the distance between your character and the three orbs. When expanding the orbit, you will be able to attack further, but your speed of movement will decrease. When contracting the orbit, your speed will increase, and you will move faster, avoiding big enemies.
Fighting relies greatly on movement and strategic positioning. Attack weak players where your orbs will easily overpower them, and leave once a stronger player arrives. Players on the Arena Leaderboard have their health indicated; this will help you make informed decisions regarding the players to attack.
After getting eliminated during the game, the game ends with players earning XP and coins for their achievements. Common skins become accessible upon leveling up. Premium skins can be bought with the coins earned, which might sometimes require specific levels to access them. Each orb has a color that can be changed using the shop color slider.
Global leaderboards have made competition more challenging by providing ways players can compete globally. Players can view ranking scores, eliminations, damage, and time played on in-game leaderboards. Leaderboards are available in daily, weekly, monthly, and all-time ranks.
