The best thing about Collaps.io is that the opponent is a person. It is free, runs in the browser with no download or account, and a round takes a couple of minutes. That makes it easy to pull up on a shared screen whenever two people are bored at the same time.

Suits friends, siblings and families looking for a quick game together, as well as solo players who prefer a human opponent online. Older children and up will get the most from it.

Is Collaps.io online or local multiplayer?

It depends on the game. Some use a shared keyboard or screen, others match you with players online, and some are turn-based. The start screen lists the modes available.

What if nobody else is online?

Online games may fall back to a computer opponent or ask you to wait. Local modes always work as long as you have a second person.

Does it keep a score across sessions?

Usually only within a session. Some games store win counts in the browser on that device, but there is no account to sync them.
