You’ve heard of Wordle so now try Nerdle. https://nerdlegame.com/ it’s a maths question, enter a calculation and work out what it should be. eg. Enter 45-33=12 Like Wordle Red entries are correct but in the wrong place and green are correct.
Another 3 today, I got some good ones in the first go which made getting it in 2 possible, but not happening today
