Shared-Device Play Is for Saying the Move Out Loud
Place the device between the two players. Sente moves first. There is no need to rush a beginner game: if a piece enters the promotion zone, pause and name what it becomes. When someone wants to drop a pawn, check the file together before the piece lands.

Let the beginner find the piece in hand before you name the square
The board shows whose turn it is and which pieces sit in each hand. Do not point straight to the answer. Ask the learner to pick a piece already on the board or a piece in hand, then say whether the next action is a walk or a drop. Finding that distinction independently is how the rule becomes clear.

Agree whether this is a lesson or a committed game
In a lesson, undo a drop that hits nifu or a promotion you chose too quickly, then compare the replacement. In a committed game, a landed piece stands and questions wait for the replay. Set the expectation before starting. After an undo, the learner should explain what the new drop denies the opponent.

Ask two questions before every drop
Does this file already hold an unpromoted pawn of ours? Would this pawn drop deliver immediate checkmate? Those two checks catch nifu and uchifuzume before the piece lands. Talking through them out loud is faster than waiting for the board to refuse the square.
