 The latter means that when a player throws X, they are allowed to rethrow the X-giving die in the hope of getting another value, and may rethrow again until the die lands on another value than X.In the Ráisa variant it is not optional which dice value is used first.One must first use the dices showing X, then use the ones showing I, following this use the ones showing II, and only then use the ones showing III.
