- If a person's dice were to land on "Daikyō", the resulting bad luck would be a cumulative equivalent of all the good luck rolls from all of the players on the island. This often results in the death of the thrower that lands on "Daikyō".
- Given that the singular form of the word "dice" is "die", the name of the item could be a play on the negative effect of the dice (the risk of the user dying).
Anime and Manga Differences
- In the 2011 and 1999 anime adaptations, the die has kanji text written on each side instead of symbols; 大吉 (Daikichi, lit. "Very Good Luck") and 大凶 (Daikyō, lit. "Very Bad Luck").
