With no repeat digits, a strategy is composed of 30 possible combinations each requiring a decision. For example, for any one of the 6 first rolls, a decision is needed for any of the 5 possible second rolls. If repeats are allowed, then 36 decisions are needed to fully describe a strategy. The maximum score is 6,543. The least is 1,234.
Many strategies are possible.
