About Wormo.io
Wormo.io takes the familiar grow-a-worm arena and hands everyone a gun. You still eat gems to get longer and still die if your head meets another worm's body, but now you can fire shots that physically push rivals — which means you can nudge someone into a wall, or into you, without ever touching them first.
That single addition changes the whole rhythm. Length is no longer the only weapon, so a small nimble worm with good aim can farm the giants, and every crowded corner becomes a shoving match rather than a stalemate.
How to play
Steer with the mouse — your worm follows the cursor. Eat gems to grow longer, click to fire a shot that shoves other worms, and hold the mouse button to boost. Kills happen when a rival head touches your body, so the useful shots are the ones that redirect somebody into your side.
Controls
- Mouse — steer
- Click — shoot (pushes rivals)
- Hold — boost
Tips to win
- Shoot ahead of a moving worm, not at it — you are pushing them, not hitting them.
- Farm the gems left by a big death instead of chasing the next kill; length is free there.
- Keep the arena wall on one side when small — it halves the directions you can be flanked from.
Wormo.io strategy guide
Three mouse actions, and the shot is what makes this one different. Move by pointing, hold to boost, and click to fire a shot that pushes other worms. Most worm games only give you steering and speed; here you have a way to move somebody else, which turns the usual game of patient circling into something much more aggressive.
Gems are the only way to grow, so keep eating. Length comes from gems, and length is what makes you dangerous. It is easy to spend a whole match manoeuvring against other players and end it no longer than you started. Eat continuously, even while you are stalking somebody — the two activities are not in conflict as long as you are travelling in a useful direction anyway.
Shots do not kill; positioning does. A shot pushes a rival, and the kill only happens when their head meets your body. So the shot is a setup tool: you fire to nudge somebody into a wall of worm you have already placed. Firing at a worm in open space with nothing behind it accomplishes nothing except telling them you are there.
Boost is your escape hatch first. Holding the button to chase somebody commits you to a fast straight line, which is the easiest thing in the world to cut off. The disciplined use is defensive: when you realise a longer worm has angled you toward its side, boost out sideways immediately rather than trying to turn at normal speed.
Let the crowd fight, then take the gems. When several worms die in the same place, the food they leave behind draws everyone still alive into the same small area. Eating along the outside of that scramble is the highest-value, lowest-risk growth in the game. The middle is where the length is, and it is also where the collisions are.

Can two people play Wormo.io on one keyboard?

How do you kill other worms?
A rival dies when their head touches your body. The shot pushes them, so use it to shove somebody into a part of your worm you have already positioned.
