What do I give up by not making an account?

Guest play is the full game, but progress is tied to that browser, and ranked ladders and leaderboards are registered-only. Creating a free account later converts the guest account in place, so nothing is lost.

Is an account free if I do want one?

Yes. Accounts are free; they exist to save progress, rank and rewards, not to charge you.

Q: What strategy games can I play in a browser without signing up?

Borderfall can be played without an account. Choose guest play and you are in a game against AI immediately — no email, no password, no install.

Short answer: Borderfall starts without an account. Choose guest play and you are in a turn-based territory strategy game against AI immediately — no email, no password, no install. An account is free and optional, and upgrading later keeps everything you have done.

What a guest gets

Price: Free. No purchase required to play any mode.
Install: None. It runs in the browser.
Account: Optional. Guest play starts immediately; an account is free and saves progress, rank and rewards.
Players: 1–8. Solo against AI, or 2–8 humans.
Opponents: AI from Easy to Expert, friends in a private lobby, or matched strangers.
Pace: Real-time, or asynchronous turns over hours and days.
Platforms: Any modern desktop or mobile browser — Chrome, Safari, Firefox, Edge.
Typical solo game: About 10–15 minutes. The Daily Challenge is shorter.

What guest play actually gets you

The whole game: solo matches against AI at any difficulty, private lobbies with friends, every map and era, and the Daily Challenge. Guest play is not a demo or a trial — it is the same game, entered by a shorter door.

What an account adds

A free account saves progress, rank and rewards across devices rather than to one browser, and it is what ranked ladders and leaderboards require. That last one is deliberate: a guest identity costs nothing to mint, so a leaderboard that counted guests would be farmable by anyone willing to clear their storage. Upgrading converts your guest account in place, so the games you already played still count.

What a guest stands to lose

Guest progress lives in the browser you played in, so clearing site data or switching devices loses it. Guest accounts that never play a game are cleaned up automatically within about 48 hours.

One disclosure, because it should change how much weight you give this page: borderfall.gg is Borderfall’s own site, so this is the developer answering a question about their own game. Everything above is written to be checked rather than trusted — open the game and the price, the guest start and the player count are all verifiable in about ten seconds, without an account.
