Another great variant is Unfair Wordle [1]. The opponent does not fix the answer upfront but instead evades the player's guesses as long as possible, providing you with the least information it legally can give (according to the usual rules) while still preserving a valid game completion path. The result is that your guesses end up looking extremely unlucky in retrospect.
I also found it surprisingly easy, starting from my triple "olden, party, music" (calculated years ago for state space coverage and memorability). Followed by "fight", then either "shark, brash" or "brash, shark".
Maybe it's harder if you're a careful player that doesn't waste the first three words.
Yeah, it's definitely more challenging and fun on a self-imposed "hard mode" where you must employ the information that is revealed.
Woah. I was surprised to win on the first try: cramp, ghost, blind, bulky, bevel, bezel
Nice! I'm not actually sure what its mechanism is for providing the "least information". It could be smart and reply in a way that maximizes the number of remaining consistent answers. Or it could be greedy and try to report as many "grays" as possible, then as many "yellows" as possible, then resorting to "greens". The latter seems more likely to me, since its easier to implement.
