Are .io games on sz.games really multiplayer?
Most of them are. Some also include bots when a room is small, so a match always has something to play against.

About .io games
The .io category collects the browser multiplayer games that became a genre of their own. Slither.io and Paper.io 2 are the simplest to start, while Territorial.io and State.io scratch the strategy itch with maps and expansion.
Many entries run against other players in real time, so a server connection is part of the experience. If a match feels empty, a refresh usually drops you into a fuller room.
How .io games usually work
You start small, collect resources, and grow by taking space from others. Slither.io and EvoWars.io use movement and collisions, Aquapark.io and Snowbattle.io are races with shoving, and Paper.io 2 and Territorial.io are about claiming and holding territory. Controls are mouse-first, with a few keyboard extras.
A fair warning about lag
Real-time games depend on the connection and on the other players in your region. The first seconds of a match can feel slow while the server fills. If a game freezes, close it from the toolbar and open it again; progress in .io matches is meant to be temporary anyway.
Common questions
Which .io game works best on a slow connection?
Turn-based and single-player-against-bots games such as Shapez.io cope best. Fast collision games need a stable connection to feel fair.
