Holey.io Battle Royale is an arena-style game that requires you to command a growing hole and battle other players until there is only one left alive.

When you start playing Holey.io Battle Royale, your hole will be quite small, and you need to think about picking up all the items that your hole can eat. You can pick up almost anything in the arena since it will allow you to grow and target larger items and even opponents.
Apart from collecting items and growing, you will face other players who will try to grow as well. This means that you will be able to pick up opponents with holes smaller than yours, and vice versa. Always pay attention to your surroundings because you may face holes larger than yours.
The battle zone will not stay constant all the way through the game. As a dead zone emerges, the playable area shrinks to force the remaining players into proximity. It is essential to keep yourself within the safe zone as the game progresses.
With power-ups, you may get some advantages when they are necessary. The speed power-up will allow you to pursue other players or leave some dangerous places, and the magnet will make object gathering easier. You can get a quick boost for your hole with size-up power-ups.
The speed power-up allows you to move quickly for two seconds, and after that needs six seconds of cooling period. By properly using the speed power-up, you may catch up to some vulnerable enemies or run away from the strong hole. Try not to get size-down signs, which will weaken your advantages.
As you play, you can unlock skins for your hole. Remember to follow locations where the boosters appear, collect objects, and pay attention to arena shrinking. With proper movement, targeting, and boosting, you can become the only hole left.
