Knife.io

Knife.io is a fast-paced and colorful reaction game where you have to throw knives at other fighters and try to survive as long as possible. There are no long preparations or pauses here: jump into the fight, and in a couple of seconds, the real battle begins. Several opponents appear on the map at once. They rush around the arena, throw knives, collect boosters, and try to be the first to hit their target. The locations are open, there is nowhere to hide, so it is important to keep moving, change direction, and be ready to attack at any moment. Each match lasts only a couple of minutes, but during that time you can knock out dozens of enemies, collect power-ups, and level up your fighter.

How to play?

In the game, you need to control a character who automatically throws a knife when close enough to an enemy. To win, move quickly, pick up boosters, increase your throwing speed and the number of knives. Bonuses constantly appear in the arena — grab them before others do. Opponents attack from all sides, and if you don't dodge in time, you lose. Each hit makes you stronger: you get more knives and your throws become more accurate. Sometimes you can pick up shields or speed boosts. This helps you survive longer and score more points. You can play with a friend on one screen — compete to see who is more accurate. The controls are simple: one button and a joystick, but you won't be able to relax. The longer you live, the faster your enemies become. Knives.io is a real reaction game where the winner is the one who can move fast, throw accurately, and keep up the pace. Choose your hero, memorize the trajectory of your throws, collect power-ups, and be the last one standing in the arena.
