A hint on the light Daylight look marking A4 with a white square, with the words "Try A4. Keeps Margaret out of the corners: some other moves would let them take one."

A game against Margaret in Sunroom Reversi on the Emerald look, big ivory and charcoal discs on a green board with yellow rings on the empty squares you can play, each showing how many discs it would turn, and the disc count for both sides in words above

Why it’s different

Reversi you don’t have to squint at

Every move ringed

A big yellow ring marks each square you can play, with the number of discs it would turn inside. Tap it and the turned discs flip over slowly, nearest first.

Hints that explain

A hint marks a good square and says why in plain words, such as "Takes a corner — corners can never be turned back". Three hints in each game are free, then a short ad of your choice gives another. Undo is always free.

Four friendly players

Daisy always plays the move that turns the most discs; Ted likes corners and edges; Margaret looks four moves ahead; Walter looks six. They see only the board, as you do. Or play a friend on the same device.

No rush, no slips

No clock. On a phone the first tap picks a square and a big Place button puts the disc down, so a slip of the finger never makes a move. A tap on the wrong square only explains why.

Easy to see

Light discs carry a dark ring so they never depend on colour alone. Three looks, three text sizes, the count in words, and the game can read every move aloud.

See it

Three looks, four players

The New game screen listing Daisy (Beginner), Ted (Casual), Margaret (Steady, chosen), Walter (Sharp) and Two players, each with a one-line description of how they play — **Four friendly players**From Daisy, a beginner, to Walter, or a friend.

The Contrast look, white and black discs with white rims on a black board edged in yellow, with yellow rings on the squares you can play — **Contrast**Black, white and yellow for the strongest contrast.

The end of a game, a yellow sun above the words You won, the final count of 55 discs to Ted's 9, games won and best run, and a button for a new game — **You won**The final count, and a sun.

How it plays

Sunroom Reversi is the old game of turning discs, laid out to be easy on the eyes. Place a disc so that it traps a line of the other player's discs between two of yours, and they all turn over to your colour. When neither of you can move, the one with more discs wins.

Every square you can play has a big yellow ring with the number of discs it would turn, so you never have to hunt for a move. The discs turn over slowly, nearest first, and the status line says what happened in words. Undo is free and goes all the way back to the start, and there's no clock.

Play Daisy, Ted, Margaret or Walter, from a beginner to a sharp player, or a friend on the same device. There are three looks to choose from: deep Emerald, light Daylight for a bright room, and black, white and yellow Contrast for the strongest contrast.

Tips

How to play well

Corners are worth the most
A disc in a corner can never be turned back. If you can take a corner safely, it's usually a good move.
Stay off the squares next to an empty corner
A disc beside an empty corner, especially the diagonal one, often lets the other player into that corner.
Fewer discs can be better early on
In the middle of the game, turning lots of discs often gives the other player more moves. Try to leave them few good choices.
Stuck? Ask for a hint
The hint says which square to play and why. Read the reason before you play, and the next one comes easier.

Questions

Asked and answered

Is Sunroom Reversi free? Are there ads?

Yes, it's free to play in your browser. An ad never interrupts a game, and there are no banners. Your first ten games have no ads at all; after that an ad may appear between games, at most once every ten games and never twice within five minutes. Undo never needs an ad. The first three hints in each game are free; after that, you can watch a short ad for another hint if you choose.

Does the computer cheat?

No. Reversi has nothing hidden, and each computer player decides only from the board in front of it. The same position always gets the same reply.

How strong are the computer players?

Daisy is new to the game and always turns the most discs. Ted likes corners and edges but doesn't always pick the best move. Margaret looks four moves ahead, and Walter six, playing perfectly once twelve squares are left.

Can I play with someone else?

Yes. Choose Two players and take turns on the same device, one playing dark and the other light.

Is there a timer?

No. Nothing in the game is timed, and the computer waits until you've seen its move.

Will I lose my game if I leave?

No. Your game is saved after every move, so you can close the page or take a call and carry on later.

Where are my statistics saved?

In your browser on this device. There's no account, and clearing the site's data deletes them.
