Two-Player Reversi

Black to playDiscs2/2

Shared-Device Play Makes Thinking Visible

Place the device between the two players and take turns placing discs. There is no need to rush a beginner game: if one move flips along a row, column, and diagonal, pause and trace each line. When a corner is given away or a pass occurs, step back together and find the cause.

Let the beginner find a dot before explaining the line

Black plays first, and the board marks legal squares with dots while showing whose turn it is. Do not point straight to the answer. Ask the learner to find a dotted square, then trace the opposing discs bracketed between the new disc and an existing disc along a row, column, or diagonal. Finding the line independently is how the rule becomes clear.

Agree whether this is a lesson or a competitive game

In a lesson, undo a move that gives away a corner and compare the replacement. In a competitive game, a placed disc stands and questions wait for the replay. Set the expectation before starting. After an undo, the learner should explain what the new move denies the opponent.

Ask two questions before every move

Will this move let the opponent take a corner next? How many legal moves will the opponent have afterward? Taking turns answering those two questions builds an understanding of mobility much faster than announcing how many discs each move flipped.
