Choosing Face Down and Revealing Together

Simultaneous reveal can keep one player from choosing after seeing an opponent's choice. It works only if selection is complete before the cards become public.

Simultaneous reveal can keep one player from choosing after seeing an opponent's choice. It works only if selection is complete before the cards become public.

In this practice round, each player places one selected card face down. Both players then confirm that their choices are locked. Only after those confirmations do they turn the cards face up. A player who dislikes the revealed comparison cannot exchange the selected card for another card in the hand.

If A reveals before B has locked a choice, the intended information condition has not been met. B has seen information that was supposed to remain hidden during selection. Do not describe that sequence as a simultaneous reveal simply because the two animations appeared close together.

The procedure needs a stated response to an early reveal, such as restarting the selection or another specified correction. That response should be agreed before play. The key checks are whether each choice was locked and whether either player saw the other card before locking.
