Many players mistakenly believe they can claim words found by others, but Boggle uses a unique elimination mechanic for duplicates.
According to the Hasbro Official Rulebook, you only score points for words that are unique to your list; any word appearing on multiple players' lists must be crossed out and earns no points for anyone.

Official Rule Breakdown
According to the Hasbro Official Rulebook (Boggle Instructions), the scoring phase begins after the timer expires and players read their lists aloud. A critical rule for scoring is that any word appearing in the list of more than one player must be crossed out on all lists. No player will gain points for these shared words. To win, the player with the highest score after the timer ends or the first to reach a pre-agreed tournament point limit is the winner.
Step-by-Step
- Step 1: Wait for the timer to expire and the red light to turn off with a beep.
- Step 2: All players must immediately stop writing.
- Step 3: Players take turns reading their discovered word lists aloud.
- Step 4: Identify any words that appear on more than one player's list.
- Step 5: Cross out those duplicate words on every player's list.
- Step 6: Calculate points for the remaining unique words.
Example Play Situation
Alice finds the word 'MOLAR' and writes it down. Bob also finds 'MOLAR' and writes it down. During the scoring phase, they both read 'MOLAR' aloud, so they must both cross it out and receive zero points for that word.

Common Misconceptions
- Thinking you can score a word if you found it first even if someone else also found it.
- Believing that proper nouns like 'France' or 'Ohio' are valid words.
- Assuming you can use the same letter cube twice within a single word.
