What This Site Is
strategogame.io is a free browser game. Two armies of forty pieces face each other across a 10×10 board, every rank is hidden, and the goal is to capture the flag. You play one side against the computer.
There is nothing to install and nothing to sign up for. The game loads in the browser, works on a phone and on a desktop, and starts as soon as the board appears.
Why It Exists
Hidden-rank games are some of the best two-player games ever designed, and almost all of them require a physical box, a table, and a second person who also knows the rules. This is a version you can play right away on a phone or a laptop, alone, without reading a manual first or installing anything.
The aim is simple: the game should be playable within one screen of arriving, and every rule should be explainable in a paragraph. That is why the rules page exists, and why the setup step lets you rearrange your army before the first move.
Original Work, Independently Made
The game engine, the interface, the piece designs, and the text of the rules and guides on this site were written and made for this site.
The game follows a well-known family of hidden-rank mechanics, and the name of that family of games appears on this site as a description of the rules. We are not the makers of the board game, we are not affiliated with its publisher or trademark holder, and this site is not endorsed by or connected to them in any way. We do not use their artwork, packaging, logos, or rulebook text.
If you are looking for the official product, this is not it. If you want to play a hidden-piece strategy game in a browser right now, it is.
How the Computer Plays
The computer opponent follows exactly the same rules you do, and it is held to the same information limits. It only knows the ranks of pieces that have already been revealed in an attack. It does not peek at your hidden ranks and it does not get a preview of your formation.
In practice this means the computer has to guess, the same way you do, and it will sometimes guess wrong.
What Is Deliberately Not Here
No account, no email address, no profile, no download. There is nothing to log into, which also means there is nothing stored about you. You can close the tab at any point and the game ends with it.
The current version is you against the computer: one opponent, one board, one set of rules.
The Rules Are Free to Read
You do not have to play to use this site. The rules page covers the full game — the board, the lakes, all forty pieces, attacks, Bombs, the Spy, and the conditions for a win or a draw. It is written to be read on its own.
