Games whose own listing promises guest play - no account, no registration, no download. Counted from our registry, not estimated.
SlowDen lists 324 games. 36 of them say, in their own listing, that you can play as a guest — no account, no registration, nothing to install.
That is not the same as saying the other 288 need an account. Most browser games need no account at all; their listings simply do not mention it, and we are not going to count silence as a promise in either direction. These are the games whose makers said it out loud.

Because it is the thing people check for. "No sign up", "without an account", "play as guest" — these are among the most common ways people phrase a search for a browser game, and a developer who answers the question in their own description is answering it before it is asked.
It also tends to signal something about the game: if there is no account, there is usually no progress to lose, no email to hand over, and nothing to cancel. You open it, you play, you close the tab.
Some games here offer one and do not require it — a leaderboard place, a saved streak, a way to play the same daily puzzle as your friends. That is a fair trade and worth knowing it is optional rather than assuming it is not.
Every game above is free and runs in a browser tab. Browse by Community, Puzzle, Horror, or see everything. Developers can submit a game.
