What to expect from the first guess
| Outcome | REACT | SLART |
|---|---|---|
| First-turn solve* | 0.04% | 0% |
| At least one green | 37.2% | 40.8% |
| Any green or yellow | 89.3% | 89.3% |
| Whole row gray | 10.7% | 10.7% |
| Worst case answers left | 253 | 252 |
*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.
SLART is not on the possible-answer list, so it cannot solve the game on turn one here. It can still be a useful guess.
