There are several synonyms that can be used in place of the phrase "went one reward." One could say that someone "achieved" or "earned" a reward, or that they "received" or "were granted" a reward. Alternatively, one could say that a person "deserved" the reward, or that they "had it coming to them."

Ultimately, the choice of synonym will depend on the context and the tone of the writing, as well as the intended audience and purpose.
