Begin with Words That Use Multiple Letters: With 8 words at once for Octordle, it's a good idea to start with where each starting word uses different common letters. Using words such as CRANE and SLATE will help you test more letters immediately.
Track Clues for Each Board Individually: keep in mind each green/yellow/gray letter for each word may have different implication for the each board without clarifiers.
Test New Letters Early: Use your first few guesses to test new letters; the more you cover early on, the fewer guesses you will need to make.
Utilize Recurring Letter Patterns: High frequency letters such as E, A, R, O, T, L, S are immensely helpful. After a couple of letters are discovered, think about probable letter groupings to reduce options more quickly.
Consider Overlaps and Double Letters: Some words may have double letters, such as LL, EE, or SS. The same letter could be repeated in more than one word, but not in the same place- noticing overlaps will help you crack the puzzle.
