Does Killer.io support online matchmaking?

Some multiplayer games here do, pairing you anonymously with another player. Others are local only. The mode selection on the start screen will tell you.

Can we play on a phone?

Turn-based and online modes work well on a phone. Shared-screen games are cramped on a small phone and much better on a tablet or laptop.

Typically one to three minutes. Multiplayer games are built for quick rematches, so a session of ten rounds fits in a short break.

The guide

Overview

Kill and hide bodies in this fun online murder game. Try to kill as many people at the Halloween party as possible. Try not to get caught.

What it's like to play

The computer never bluffs. A person does. Multiplayer games here are built around that difference, whether you are racing a friend on a shared keyboard, taking turns on a tablet, or matched against someone online. Rounds are quick and often close. A session is a running tally of wins and losses that neither side is quite ready to leave alone.

How to play

1Read the mode list on the start screen and pick local, online or turn-based.
2If playing on one device, settle who controls which side before the round begins.
3Learn the one or two actions your character has and practice them in the first round rather than trying to win it.
4Keep playing rounds; the running score matters more than any single result.
