Morphology

on + a + roll

The phrase relies on a metaphorical extension of 'roll' (continuous movement/momentum) so there is a plausible link to a sequence of successes, but the specific sense 'experiencing continuous success or luck' is not directly or predictably derived from the literal meanings of 'on' + 'a' + 'roll' by an average B1 learner. The underlying concept (a streak of success) is common cross-linguistically, yet the mapping to 'roll' is idiomatic enough that prior exposure or explanation is typically needed.

Etymology

On a roll may come from playing with dice: when the dice kept rolling good numbers, the player kept winning. So, being on a roll today means 'doing very well for a time'.
