Morphology
The phrase uses 'on' to mark a current state and 'game' in a figurative sense for one's performance or skill, so a learner who knows the words may partially infer it means being 'in good form' or performing well. However, the figurative extension of 'game' to mean competence is idiomatic and not fully predictable without exposure, so it is only partially transparent to a B1 learner.
Etymology
The phrase on one's game comes from sports: imagine a player who is literally on their game, in the match, fully focused and making the right moves. So, saying someone is on their game today means they are 'performing at their best'.
