Stratego

Deploy a hidden army, outwit your opponent, and capture the enemy flag in the computer version of the classic game of military deduction. Stratego is yours to play at no cost, with no download, no configuration and no sign-up. This computer adaptation of the board game opens in seconds and keeps the bluffing, the memory work and the sudden reveals fully intact. Forty pieces share a crowded grid, and picking up the one you actually meant is easier with a mouse than a fingertip.

How to Play Stratego Online

Getting into the game takes seconds:

1. Press Play to bring up the board and your computer opponent.
2. Give it a second while both armies are laid out — none of this leaves the page.
3. Click the frame once first, so a piece gets picked up instead of the page scrolling.
4. Set up your army, placing your pieces (including your flag and bombs) on your side.
5. Take turns moving and attacking to capture the enemy flag.

Stratego is a game of hidden information — you can't see the enemy's ranks, so deduce them from their moves and protect your flag carefully.

Controls

Stratego is played with the mouse, on a grid board:

You can see your own pieces' ranks but not the enemy's — so pay attention to which enemy pieces move and how they fight, and remember what you learn to deduce their strengths.

What Is Stratego?

Stratego is a computer adaptation of the classic strategy board game of hidden ranks and military deduction. Played on a grid, each player commands an army of 40 pieces, each with a hidden rank — from the powerful Marshal and Generals down to lowly Scouts and Miners, plus immovable Bombs and the all-important Flag. The crucial twist is that you can see your own pieces' ranks but not your opponent's, so the game becomes a tense battle of bluffing, memory, and deduction as you try to capture the enemy's Flag while protecting your own.

Stratego is a beloved classic of hidden-information strategy, often described as a blend of chess and battleship with a heavy dose of psychology. Because ranks are concealed, you must deduce your opponent's pieces from their movements and the outcomes of battles — when two pieces clash, the lower rank is removed, revealing information. Special pieces add depth: Bombs destroy most attackers, Miners can defuse Bombs, Scouts move long distances to probe enemy lines, and a Spy can assassinate the powerful Marshal. The computer version provides AI opponents and handles the rules, delivering all the bluffing, memory, and tactical depth of the board-game classic.

How the Game Works / Gameplay Basics

The game begins with army setup: you secretly arrange your 40 pieces on your side of the board, deciding where to place your strongest units, your Flag (which you must protect), and your defensive Bombs. Because your opponent can't see your ranks (and you can't see theirs), this hidden deployment is the foundation of the whole game — a clever setup can protect your Flag and lure the enemy into traps. Once both armies are placed, you take turns moving one piece at a time across the grid.

The heart of Stratego is combat and deduction. When you move a piece onto a square occupied by an enemy, the two reveal their ranks and the lower-ranked piece is removed (ties remove both) — so every battle both resolves a fight and gives away information about the pieces involved. Your goal is to capture the enemy Flag, while using your knowledge, memory, and bluffing to outmaneuver your opponent. Special rules add tactics: Miners defuse Bombs, Scouts zip across open rows to scout and strike, and the Spy can defeat the Marshal if it attacks first. Remembering revealed pieces, probing the enemy lines, protecting your Flag, and reading your opponent's intentions are all key. It's a deep, psychological game where deduction and nerve win the day.

Beginner Tips

• Protect your Flag. Surround it with Bombs and strong pieces to keep it safe.
• Remember revealed pieces. Track which enemy ranks you've uncovered.
• Use Scouts to probe. Send Scouts to reveal enemy pieces and gather information.
• Keep Miners safe. You'll need them to defuse the enemy's Bombs.
• Bluff with movement. Move weak pieces boldly or strong ones cautiously to mislead.
• Don't reveal your big pieces early. Keep your Marshal and Generals hidden until needed.

Why Play Stratego Online?

A tab is all it takes to sit down to a game of concealment and deduction. Nothing needs installing and nothing needs configuring: the version that arrived on floppy disk, and the box of plastic pieces before it, are both replaced by a single click. A match lasts long enough to be interesting and short enough to finish in an evening, whether you grew up moving these ranks around on cardboard or have never guarded a flag before.

Your hard drive is never touched, so the same forty-piece army deploys on whichever computer is in front of you. For a design that has outlasted most of its contemporaries, one click is a fitting way in.

Troubleshooting

• Game won't start? Reload, then wait until the whole grid has drawn, the two impassable lakes in the middle included, before you try placing a piece.
• Mouse or keyboard not responding? During setup your first click is often spent focusing the game frame rather than picking up a piece, so click once inside it before you start placing.
• Board hard to see? Use fullscreen mode; the rank numbers on your pieces are small, and mistaking a Miner for a Marshal loses games.
• Running slowly? Close other browser tabs and heavy applications, though the one delay you should expect is the computer thinking through its own turn.
• No sound? There is little to miss here beyond move and capture effects, but if even those are silent, unmute the tab and turn the system volume up.
• Losing often? Protect your Flag better, remember revealed pieces, and scout the enemy lines.

Frequently Asked Questions

Do I need to download anything, or own the board game? No. Everything arrives in the page once you press Play, and there is no account to create.

Can I play Stratego on mobile? You can, but each piece is a small labeled square on a busy grid, and a pointer is far more precise than a fingertip when one stray tap spends your whole turn.

Is this based on the board game? Yes, it's the computer adaptation of the classic Stratego board game of hidden ranks.

How do you win Stratego? You win by capturing your opponent's Flag (or leaving them unable to move), using deduction and tactics.
