Is the word surpresas the same in Brazilian and European Portuguese?

Yes

The word "surpresas" is identical in spelling, meaning, and grammar in both Brazilian and Continental Portuguese. The only differences are phonetic:

• Vowels: In Brazilian Portuguese, vowels are generally more open and clearly articulated. In Continental Portuguese, vowels are often "reduced" or "swallowed," making the word sound much shorter and more closed.
• Sibilants (the "s" sounds): In many Brazilian regions, the "s" in the middle of the word is a soft [s] (as in "sun"). In Portugal, this "s" is almost always pronounced as [ʃ] (as in "shoe"). Similarly, the final "s" in Portugal is a strong "sh" sound, whereas in Brazil, it varies by region but is often a softer [s].
