How to play Reversi Flip
The board is 8 by 8. Four discs sit in the middle at the start: two purple, two navy, crossed over each other. Purple moves first. Your goal is simple to say and hard to do: finish the game with more discs of your colour on the board than your rival.
- Look for the dots. Every square where you may legally play shows a soft gold dot. If a square has no dot, a disc there would flip nothing, so it is not a legal move.
- Trap a line to flip it. Place your disc so that one or more rival discs sit in a straight line between your new disc and a disc you already own. The line can run across, down, or on a diagonal. Every trapped disc flips to your colour.
- One move can flip many lines. A single disc can trap lines in several directions at once — across and diagonal in the same move, for example. All of those lines flip together. These are the biggest moves on the board.
- Pass when you are stuck. If you have no legal move, your turn passes to your rival. The game tells you when this happens. Being stuck early is normal; being stuck late is often fatal.
- The game ends when nobody can move. The board does not need to be full. When neither side has a legal move, the discs are counted, and the side with more discs wins.
The disc count under the board updates after every move. Watch it, but do not chase it: the player with fewer discs in the middle of the game often wins, because a small, tight group of discs is hard to flip, while a big sprawling group offers the rival long lines to trap.
The rules, exactly as this game plays them
Reversi Flip plays the standard reversi game on an 8 by 8 board. Here is every rule the game enforces, with no surprises.
A move must outflank. You may only place a disc on an empty square if it traps at least one rival disc in a straight line between the new disc and one of your own discs. Lines run in all eight directions: left, right, up, down, and the four diagonals.
Every trapped line flips. If your disc traps lines in three directions at once, all three lines flip. There is no choosing: the game flips everything your move traps.
A stuck player passes. If you have no legal move, you miss your turn and your rival moves again. If your rival is also stuck, the game ends at once, even with empty squares left on the board.
Most discs wins. When the game ends, the discs are counted. More discs wins. Equal counts are a draw. A side can even win with empty squares still on the board, if neither player can use them.
Why the name? The game is called Reversi because that is its original public name. The name Othello belongs to a trademarked board game product, so this free browser version uses the classic name and its own original design.
Controls for phone and PC
| Action | Phone / tablet | PC / laptop |
|---|---|---|
| Place a disc | Tap a dotted square | Click a dotted square |
| See a suggested move | Tap Hint (3 per game) | Click Hint (3 per game) |
| Take back a move | Tap Undo | Click Undo |
| Give up the game | Tap Resign | Click Resign |
| Change mode or level | Tap Menu | Click Menu |
Against the computer, Undo always takes back a full round — your move and the reply — so you land exactly where your last decision began. The Hint button rings one strong square in gold; you get three hints per game, so save them for the moves that shape the board.
The computer level ladder
One player means a ladder of four computer rivals. You start with Level 1 open. Beat a level to unlock the next one, and your wins, losses and draws on every level are saved, along with the highest level you have beaten.
| Level | Name | How it thinks | Best for |
|---|---|---|---|
| 1 | Rookie | Picks from its legal moves at random | Learning the rules and your first wins |
| 2 | Casual | Grabs the move that flips the most discs right now | Relaxed games with a real fight |
| 3 | Skilled | Scores every square by position: corners first, traps avoided, room to move kept open | Players who already think about corners |
| 4 | Master | Searches five moves deep with position and mobility scoring | A serious test for strong players |
Every level plays by the same rules you do. The higher levels do not cheat and do not place extra discs. They simply value the right squares, keep their options open, and punish a gifted corner much harder.
Strategy tips that win games
- Corners are forever. A disc in a corner can never be flipped, and it anchors every line that touches it. Every plan in this game starts with one question: does this move help me take a corner, or hand one to my rival?
- Beware the squares beside the corner. The three squares next to an empty corner are traps. Play on one too early and your rival takes the corner itself on the next move. Only step there when the corner is already yours, or when you are sure the rival cannot reach it.
- Keep your discs few and tight early. It feels backwards, but a small group of discs in the middle is strong. It gives the rival few targets, while their big group gives you long lines to trap. Many beginners lose by grabbing discs too fast.
- Count your moves, not your discs. Having more legal moves than your rival is the real lead. A player with moves can choose; a player without moves passes, and every pass hands the other side a free turn. Late in the game, forcing a pass is worth more than a five-disc flip.
- Take the edges in pairs. Discs on the edge are harder to flip than discs in the middle. Build along one edge toward a corner, and your discs become a wall the rival cannot turn.
- Save the big flips for late. A huge flip in the middle of the game often spreads your discs out and offers the rival even bigger lines back. The same flip on the last few moves is pure profit: there is no time left to answer it.
- Watch the last empty squares. The game can end with empty squares on the board. Near the end, count who gets the final moves. Playing the very last move is often the difference, because the last discs placed can never be flipped back.

Reversi Flip FAQ
Is Reversi Flip free to play?
Yes. Reversi Flip is 100% free. You play it right on this page, against the computer or with a friend on the same device. There is no download, no sign-up and no payment.
What are the rules of Reversi Flip?
Place a disc on an empty square so it traps one or more rival discs in a straight line between your new disc and one of your own. Lines run across, down and diagonally, and every trapped line flips to your colour. If you have no legal move, you pass. When neither player can move, the side with more discs wins.
Why is the game called Reversi and not Othello?
Reversi is the original public name of the game. Othello is a trademarked product name, so this free browser version uses the classic name, its own board design and its own code.
How do the computer levels work?
There are four levels: Rookie, Casual, Skilled and Master. Rookie picks a random legal move. Casual grabs the biggest flip. Skilled scores squares by position, taking corners and keeping its moves open. Master searches five moves deep. Beat a level to unlock the next one.
Can two people play on one device?
Yes. Pick 2 Players on the start screen and pass the device back and forth. Purple moves first. The legal moves for the player to move are dotted, the game keeps the match score for the session, and a player with no legal move passes automatically.
Does the game save my progress?
Yes, in your own browser. It keeps your unlocked level, your wins, losses and draws on every level, and the highest level you have beaten. Nothing leaves your device, and there is no account to make.
Final verdict: should you play Reversi Flip?
Yes — if you like games that look calm and bite hard. Reversi Flip is the real game: outflank in eight directions, flip whole lines at once, pass when you are stuck, and fight for corners that can never be taken back. The four-level ladder grows with you, from a friendly Rookie to a Master that plans five moves deep, and the two-player mode turns one phone into a board you can share. Take a corner, and take the game.
