The goal

Last one on the floor wins. There are two ways out: you fall off the stage, or you run out of lives. Everyone starts with 3 lives, and getting caught on red costs one.

How to knock people off

The floor

The stage is one big LED screen. Jump over red and land on green. Green pads give you points, and clean jumps give you more. The patterns start slow and easy, then get faster and harder with every level. Stay long enough and sudden death starts, when getting caught on red puts you out straight away.

Ways to play

Choose 1v1v1 for three on the floor, or 1v1v1v1 for four.

Characters and KO Points

Every match you finish pays KO Points, with more for placing well and for knockouts. Spend them in the Locker to unlock characters: there are 131 in all, and 36 are free from the start. Each week, five exclusive characters go on sale for seven days, and once you unlock one it is yours to keep.

Tips

Questions

Is KO Jumper free?

Yes. Every mode is free to play in your browser, and you earn new characters just by playing.

Do I need to download anything?

No. KO Jumper runs in your browser and opens straight into the game, with nothing to install and no sign-up.

Can I play with friends?

Yes. Choose Friends, create a room and share its four-letter code or link. Up to four can play in a room, and bots can fill any empty seats.

Does it work on a phone?

Yes. In a recent phone browser you get an on-screen stick plus Hit, Block and Jump buttons.

What do I need to run it?

A recent version of your browser with hardware acceleration turned on. If the game can't start, updating the browser usually fixes it.

Are the other players real?

Play online puts you in with other people, and bots fill any empty seats so a match can start right away. Bots always show BOT next to their name. Practice is all bots.

Do I need an account?

No. Your KO Points and characters are kept on your device, in this browser, so clearing the site's data removes them.
