Guess the physics word of the day in 6 tries. Every guess must be a word from the list (particles, units, scientists, optics, astronomy… from quark to laser to milky).

After each guess the tiles change colour: Q right letter, right place · Q letter is in the word, elsewhere · Q letter is not in the word.

A new word appears every day at midnight, your local time, the same for everyone. Your progress is saved in this browser only.
