Reversi, free to play

Trap the computer's white discs between your black ones and turn them over. Three levels, with hints and undo.

How to play

Place a disc
You are black and go first. Tap an empty square where your new disc would trap a line of white discs against another black disc.
Turn them over
Every white disc trapped that way turns black. Then the computer does the same to you.
Finish with the most discs
When neither side can move, whoever has more discs wins. If you have no move you pass, and so can the computer.

Quick answers about playing Reversi on Wittlo.

Is Reversi free?

Yes. It is free to play, with no sign-up and nothing to install.

Who is it against?

The computer. There are no other players and nothing is sent anywhere. Choose Easy, Medium or Hard.

What if I cannot move?

You pass and the computer plays again. If neither side can move, the game ends and the discs are counted.

Any tip?

Corner squares can never be turned over, so they are very valuable. Try not to give the computer a corner.

Can I take a move back, or get a hint?

Yes. Undo takes back your last move, and Hint marks a good square to play.

Is my game saved?

No. A game is quick, so one you leave part-way is not kept.
