In this case, I'd think "well, I want to tell if a game is finished, (or if it has a winner)." So, you could add:

```ruby
def finished?
  @winner != nil?
end
```

Then, it would make your spec a little easier to reason about:

```ruby
game.finished?.should be_true
```

Or, you could:

```ruby
attr_reader :winner
```

Then, it's as easy as:

```ruby
game.winner.should be_present
```
