## Purpose and Scope
|
|
|
|
The system boundary is the Higher Lower console game. One actor, the Player, uses it to play a game. Traces to [BC-001] objective O1 and to stakeholders S01 and S02 ([SA-001]), who play the game; S03 only reads the repository.

|
| Use Case | Actor(s) | Goal |
|
|

|
|
| Play a Game ([UC-001]) | Player | Guess, round after round, which of two accounts has more followers, and see the final score |
|
|
|
|
## Relationships
|
|
|
|
None: there is a single use case, so no `<<include>>` or `<<extend>>` is used.
