You must play the card drawn from the discard pile

If this rule is in place, then if you draw a card from the discard pile, you must play it onto the table in that same turn. It is not allowed to keep that card in your hand.

In games where you may draw more than one card from the discard pile, this limitation only applies to the last card you draw.

Games with this rule

In Tonic RRRummy, you must play the last card that you draw from the discard pile; in Jin RRRummy, this rule doesn't apply. Other built-in games in RRRummy don't use a discard pile at all.
