Take another look at the sentence:
A tantalizing smell had drawn Richard to the edge of his neighbor's yard. Finally, temptation winned, and he crept across the lawn to the open window, where he spied chocolate-broccoli muffins cooling on the kitchen counter.
The second verb, winned, is the problem. The sentence requires the simple past. Won is the correctly spelled form.

Crept, the verb you chose, is perfectly correct. Before you continue, review the rules for irregular verbs.
