Reversi Classic

Mission briefing

Reversi (Othello) in beautiful 3D — the classic strategy game where one move can turn the whole board. Sandwich your opponent's discs between yours to flip them, and finish with the most discs to win. Play 5 computer levels from Novice to Master, ranked online matches with Elo rating, games with a friend by room code or on one screen, and a daily puzzle with the same position for everyone. Unlock dozens of discs and boards — marble, gold, gemstones, animated legendary discs and themed tables — and progress through a 40-tier season pass with daily and weekly quests. A friendly 2-minute interactive tutorial takes you from zero to your first win.

Field manual

Goal: have more discs of your color on the board when the game ends. Players take turns placing one disc. A move is only allowed where it sandwiches at least one opponent disc in a straight or diagonal line between the new disc and one of yours — all sandwiched discs flip to your color. Dots show legal moves. If you have no legal move, your turn passes; the game ends when nobody can move. Tip: corners can never be flipped back, so grab them. Controls: click or tap a cell to place a disc (mouse, touch). Hover or hold to preview what will flip (training mode). Esc opens the game menu.

Launch orders: press Launch mission above and the game loads on this page itself — nothing downloads and no form stands between you and the first move. It is designed for a flexible screen and takes its orders from mouse, keyboard or touch, depending on the mission. It adapts to both upright and wide screens, so phones, tablets and desktops all frame it sensibly. If it offers a fullscreen control, use it — a fight this size deserves the whole screen.

Field notes for strategy operations

• Economy first, army second. The player who builds one more resource structure in the opening minutes out-produces the player who built one more soldier — arithmetic is the quietest weapon in strategy.
• Scout before you commit. Every strategy game hides a paper to your rock; two minutes of reconnaissance is cheaper than twenty minutes of building the wrong answer.
• Hold a reserve. Committing everything to the first fight leaves nothing for the second, and there is always a second — usually arriving while you are still rebuilding from the first.

Reversi Classic — questions from the ranks

Nothing at all. The mission is free from the first order to the last — no sign-up, no download, no paid tier guarding the good levels. The advertising around this page is what keeps the board free.

What sort of mission is Reversi Classic?

Reversi Classic is filed in our Strategy theatre. Like every operation on this board, it is a browser game — read the briefing above for the publisher's own account of what you are deploying into.

Can I run Reversi Classic on a phone or tablet?

Yes. It plays in the browser on phones and tablets exactly as it does on a computer. It adapts to both upright and wide screens, so phones, tablets and desktops all frame it sensibly.

Do I have to install anything before playing?

No installation of any kind. Reversi Classic is an HTML5 game: press the launch button and it loads on this page, and closing the tab leaves nothing behind.
