The daily puzzle hides an eight-character arithmetic equation instead of a word, and you get six attempts to find it. Tiles turn green or purple to show which digits and operators sit in the right place, so solving becomes a mix of mental arithmetic and constraint elimination.
Because the answer has to balance as a genuine equation, one confirmed digit can collapse dozens of remaining possibilities at once.
