Opener Lab
BIOSE vs TRACE
See which word leaves you with the easier game.
These game-length figures come from the previous complete opener benchmark against its 2,354-answer snapshot, ranked by average guesses among games solved within six. Its answer snapshot and continuation policy are separate from today's solver recommendations.
The same solver played from both openers. TRACE has the lower average in games solved within six: 3.53 guesses to 3.69 for BIOSE.
Looking only at the opening row, TRACE has higher entropy (5.82 bits versus 5.15). That describes first-guess separation, not the full solve on its own.
| Metric | BIOSE | TRACE |

| Elimination | 95.2% | 96.8% |
| Information | 5.15 bits | 5.82 bits |
| Avg remaining | 114 words | 76 words |

What to expect from the first guess
| Outcome | BIOSE | TRACE |
|---|---|---|
| First-turn solve* | 0% | 0.04% |
| At least one green | 42.1% | 42.1% |
| Any green or yellow | 89.4% | 89.3% |
| Whole row gray | 10.6% | 10.7% |
| Worst case answers left | 272 | 253 |
*Treating every word in the possible-answer list as equally likely.
Both openers come back completely gray at almost the same rate, so the difference between them lies in how much their hits actually tell you.
BIOSE is not on the possible-answer list, so it cannot solve the game on turn one here. It can still be a useful guess.
How these two openers fit together
BIOSE and TRACE overlap on a single letter (E), so the pair tests 9 different letters between them.
Played back to back, BIOSE then TRACE earns 8.70 bits of information in total, 2.88 bits more than the better word manages alone.
