Start with vowel-rich words like ROUBO, IDEAL or AΓREO to quickly filter common letters. Avoid repeating letters in early tries to maximize the information you extract from each attempt.
Once you know two or three correct letters, think of high-frequency Portuguese words: AGORA, MUNDO, PORTA, NOITE are strong candidates. Use the second guess to test consonants completely different from your first. And remember position matters β a yellow tile in slot two is NOT in slot two of the answer.
