How verification and withdrawal work

The answer word and timezone are used transiently to verify this page, then discarded. The receipt prevents duplicate submissions and lets this browser withdraw later; anyone with that token can withdraw, so keep browser-data exports private. Read the full privacy details.

First-turn measures

All four describe OXIDE used as an opening guess. Entropy is the same idea as “avg ruled out” on a log scale: a higher number means the guess splits the possible answers into more, smaller groups.

4.23 Entropy (bits)
209 Avg remaining
0.04% Exact match
91.2% Avg ruled out
Higher first-turn entropy than about 35% of evaluated openers
1.71 bits below the highest measured first-turn entropy (~5.95 bits)
