Quick answer: Both spoilt and spoiled are correct past tense forms of the verb spoil. The main difference lies in geography rather than grammar. Spoiled is the standard choice in American English, while spoilt is widely accepted and common in British English contexts.

The Short Answer

Both spoilt and spoiled are grammatically correct forms of the past tense and past participle for the verb to spoil. You can use either depending on your audience and regional preference.
