Immortle is a Wordle-style daily word game made of Counter-Strike terms. You get six guesses, and each one shows which letters are right, which are in the word somewhere else, and which are not in it at all. A line under the board names the kind of term you are looking for.
Every game on the site has its own daily puzzle, and everyone playing Counter-Strike gets the same word that day. The reveal explains the term in a line. Free play has no limit, and hard mode makes you use every hint you have found.
