Find the word. Follow the letters.
Loading the word library…
Find the hidden STEM word. The board shows whether it has five or six letters. You get one more guess than the number of letters.
Use your keyboard or the keys below the board. Any word in the guess dictionary is allowed; answers always come from the STEM library. Repeated letters count only as many times as they occur in the answer.
New puzzles open at 7 a.m. and 11 a.m. Eastern time, including daylight saving time. Both remain available until the next 7 a.m. release. An unfinished puzzle with at least one guess counts as a loss when it closes. Untouched puzzles do not affect your record.
Guess 1: 100 · 2: 85 · 3: 70 · 4: 55 · 5: 40 · 6: 25 · 7: 10. An unsolved puzzle scores 0. Time never affects your score.
