# There has GOT to be a better way to identify what is wrong with the challenge instead of just "Bummer! Try again!"

Beating my head on the wall again!
Assuming a hand size of 5 for Yatzy, checking to see that the _score_set returns truthy for five values, should be enough. I tried checking that the hand size was 5.

I tried testing with 7 different hands. hand[:] = [one, three, three, four, four] hand2[:] = [one, one, one, one] hand3[:] = [one, one, one, two] hand4[:] = [one, one, one, one, one] hand5[:] = [one, one, one, one, two] hand6[:] = [one, one, one, one, one, one] hand7[:] = [one, one, one, one, one, two]

When hand size wasn't limited to 5, both hand4 and hand7 returned 50. When hand size was limited to 5, only hand4 returned 50.

```class YatzyScoresheet:
def score_ones(self, hand):
return sum(hand.ones)

def _score_set(self, hand, set_size):
scores = [0]
for worth, count in hand._sets.items():
if count == set_size:
scores.append(worth*set_size)
return max(scores)

def score_one_pair(self, hand):
return self._score_set(hand, 2)

def score_chance(self, hand):
return sum(hand)

def score_yatzy(self, hand):
#if len(hand) == 5 and self._score_set(hand, 5):
if self._score_set(hand, 5):
return 50
return 0
```
