I think you missed what I said. I started out from the point of signing into the Lex email site. It is at THAT point that there is a horizontal list of what you can do. That list shows: Play Live -- Email Version -- Practice -- Puzzles -- Stats -- Archives.
What I described in my last note relates to THESE selections, at the original site.....NOT after you have already selected one of them, such as Puzzles.

@betterlate1 Well, at least you made me laugh! NOW I don't know what OSPD is, so you'll have to explain. Since AARP tells us we are to keep our brains sharp, and I'm quite isolated, I try to find things to do independently online. So I want them to be challenging and fun, not add annoyance (for me).
To guide you about what I'm doing: I use the "Lexulous" in the email setting, not at facebook. Here is a link, just in case you are somewhere else: https://www.lexulous.com/email/
At that site, there's a horizontal list of what's offered. You can choose to play with someone listed, or a friend who's in your friend listing. You can also choose to "Practice"; and if you do so, you then state whether you want to play against a robot or yourself. Then there is the choice of "Puzzles", which I just very recently realized, and which has been my primary focus in these chats.
It seems to be in a development/test stage. They state you are playing some game that actually is in their files from the past. I don't know at what stage they post it, so I don't know if the "last player" is from back then, or it is someone who just played in the Puzzles setup. I've played so many now, I think I'm getting the same ones back -- maybe not too many people play in Puzzles. You ARE playing Lexulous, but you only take one crack at the game they give you, trying to beat the score of the last player. (This is why I don't understand the posting for "AI") You may have a full rack or very few letters. The game is usually well along. You're given your actual score for that round. Also, in green you see how many points above the "last player" you scored, or in red you see 0 if you tied and a negative amount if you lost. You then ask for the next "puzzle." So you're playing Lexulous, but (unless they pass the same game back later) you only do that one action for each game presented. You can also choose "give up." But I found out today, the hard way, that you should only do that if you can't play for at least SOME points. The previous player must have had a bingo, as the score was very high. Don't know why I hit "give up" -- probably focusing on how many points I was going to lose -- but I did, and they subtracted the whole 60+ points from my running totals, thus also lowering my standing. I learned! As for DIQUAT, yes, when I looked it up I saw it was an herbicide; but it looked like it was the name of the brand. Perhaps I got that one confused. But there was no "normal" dictionary reference to it, only a Wikipedia explanation. Sorry I wore you out, lol. I've had a very difficult day, too, but have trouble falling asleep, so push myself at night. Maybe at some point, if we both wind up at the same site, we can set up a real Lexulous game and see how the rules work there now.

@betterlate1 I guess I didn't explain well. I don't deliberately go out to different dictionaries to find words. And, like you, I keep a list of those with which I'm not familiar, so I can learn new ones. My point is that I'll set up a search periodically, to look up many at a time, and that is when I find out the words don't exist. I never saw the musical definition you provided as a "dictionary word" -- it was finally seen squished between other things. But many of the results I find are not straight dictionary supports, but bring me to a business, whose acronym or actual name is being used by the robot. "NY", which I only know as a state abbreviation is one. (And, please note, the Lexulous Puzzles dictionary does NOT accept NY, even though the robot was allowed to use it against me in PRACTICE.) Yes, I WANT to use only one dictionary....it is the frustration with being hit with endless crazy words during one practice session with the robot (not during Puzzles play) that is maddening to me. Have you played the robot in Practice? If not, try it and perhaps you will see what I mean. Yes, I agree that there are lots of words to learn. I started playing Lexulous on the fb site about 13 years ago, switching to the email site when I left fb over 4 year ago. I played with people from within and outside the US, so we alternated in dictionary applications to be fair -- eg, using UK one game, US another. So I long ago learned that whereas US uses only (your example of) ZA, the UK also uses ZO. Yes, that is the way it is actually FUN. I already pointed out that things like monetary units in different countries can introduce variety we accept, and I have no problem with that. I don't expect to know the entire legitimate language. It is the words I look up and cannot find definitions for that aggravate me. I had numerous pages full until I finally threw most away and just quit playing against the robot. When I looked up the robot's word VIVACE, I was taken to a restaurant by that name, not to a dictionary. DIQUAT turned out to be a brand name. The Puzzle game accepts them, but does not give a definition (there is a place to ask for one, but it doesn't seem to work).
I mentioned earlier that TE is suddenly appearing as an acceptable 2-letter word. It never was acceptable during the years I played Lexulous. When I look it up, the only definition I get is it is Spanish word for tea. Well, to me it is ridiculous to accept odds and ends words from many languages (like the Serbian I referred to earlier) unless they have actually been adopted into our speech -- such as adios, or ole. To just (inconsistently) grab any old word from any language is not keeping in the spirit of what we used to consider a dictionary. And if the word is looked up online, we shouldn't have to be told it's in wykadictionary or "free dictionary" or some other non-standard reference. I am an older person, and I realize the language changes over time; but then the new words ought to be in an approved dictionary for use in games. Things like CRWTH are a bit trickier, as Welsh and Scot. are treated as subsets of British English. But it gets hairy after that. Back in the dark ages, when I was in HS and preparing to take College Board Entrance Exams, I'd skip lunch to join a group led by teachers, to help us prepare. And I can still see the English teacher stressing the meanings as we went over words. One that stuck is FULSOME. It was pounded into us that it was a NEGATIVE word, not to be fooled by the sound. When I reached early adulthood, I remember an entire article in the NY Times magazine section, written by William Safire, on the word FULSOME! He was obviously frustrated about its misuse. Years later, after an airplane problem, when a pilot safely delivered the plane to the tarmac, CBS TV station was stating how "fulsome" the passengers were in their praise of the pilot. Ouch! I tried calling them to correct them. Well, fast forwarding to more recent times, not only does the regular dictionary now define the word in two OPPOSITE ways, but it also has a third definition of meaning something to the effect of "full of." I'm not bothering to look it up just now, and it may have changed again. So, I hear what you are saying, and I'm glad you can enjoy playing. But I don't enjoy the setup as is -- with words that are truly not "vocabulary" words (like NY), nor foreign words (aside from things like monetary units) that have not really become standard use in the English language. (But I agree with you that just playing to gain my own strength is my goal -- but I have to stick to Puzzles to do that. I can't deal with the idiocy in the robot games.) As I stated, I played Lex for years without this problem. I'd rather stick with "game rules". There are enough REAL words for us to learn by playing others who know them, without having to deal with inaccurate or such obscure use of many that it feels like you're playing in some other language. But.... again... I'm glad you (and, most likely, others) are happy with it as is.
I'll just leave one more thought to ponder -- why is it that I'm seeing so FEW unfamiliar words when playing Puzzles than the bombardment of them I get from the robot in Practice? Perhaps, as I noted about "ny", the different playing areas are being subjected to different rules.

@betterlate1 Well, you've now clarified something for me, too. I accessed the blog forum through the Puzzle game, not realizing it is for Lexulous in general. But I take a different view from you about the legitimacy of words used in the PRACTICE section against the ROBOT. I do not know if the rules are different when actually playing against another player, since I've not done so in a couple of years. And I don't know what is in use when playing against SELF for practice, as the one time I tried that was quite boring. I'd tried playing a similar word game online, then wrote to Arkadium (the producers) when frustrated with the illegitimate words used. They responded that they were okay in THEIR dictionary, comprised from all over the world. About 1 of every 3 words I looked up turned out to be the name of a company, an acronym, an abbreviation, or some word just plucked from another language (Serbian was one), which we do NOT use in English language, like we might use many from other languages. They were also not somewhat unknown word like monetary values of another country, which I'm used to appearing. They simply are NOT words consistent with US English vocabulary, even if I'm a bit behind the times. I have found the SAME situation in playing the robot (AI) in Lexulous PRACTICE, and I suspect that it reflects what the AI score reflects in the PUZZLES. On the other hand, while a few words/spellings have been new to me in the PUZZLES, - FROM THE "LAST PLAYER" - they do NOT appear to be the ridiculous ones used by the robot here or in other games. I've exceeded scores of the robot's entries frequently, in both Lexulous Practice and other games, so that is not the issue. It is just the frustration of constantly seeing words that I cannot locate in ANY dictionary, -- and they use "Free Dictionary", "Informal" and "Wictionary" as sources of definitions one CAN find, if at all. One example is CRWTH. I cannot find it anywhere. To me, we might as well throw anything on the board to see if it's accepted if we are not using a standard dictionary to guide all entries.....but, as I've shared, I think they DO control more in actual puzzles. "Puzzles" are games from the past, from what they explain, so perhaps that is why I'm finding the vocabulary acceptable. I doubt the AI is being subjected to the same sources that the "last player" was. Thank you for the contact source. If I can get many other more necessary issues addressed, I'll try contacting them about the problem, too. But, I fear I'll get the same response I received from Arkadium about the other game. BTW, in PUZZLES, I think I saw NE listed in the two-letter list. I had selected US English. Till this last week, that was not accepted. Apparently US English suddenly does. For me, personally, this loose set of rules ruins the games.

@betterlate1 Hi...the section to the right of the board displays the puzzle number at top, and "your puzzle rating/ranking" lower down. In between those there is a list of three lines: "My Score", "Score to Beat", and "Al Score" Although I now know they are probably referring to the robot, I don't know WHY. I've practiced against the robot, and it uses all sorts of illegitimate words, acronyms, proper nouns and abbreviations. I'm not seeing those (so far) on the many puzzle boards I've played, so I don't know what that has to do with the puzzle version. I'd rather they left that out and also cleaned up the allowed vocabulary in "practice", so it would emulate a game users actually play against one another.

@Leslie-Platt Thank you! Now you have me curious about what it would mean to a livestock-breeding farmer. I used to be an OTR - meaning Registered Occupational Therapist, but the simple reference to OT was used. Then it came to mean "overtime" and other things. The main prob I was having here is that I didn't know whether the "l' was a an upper case i or a lower case L -- since this font shows both the same. I'm not sure why they are including the "artificial intelligence" score since we are not playing the robot, but an old game of humans. And when I've played "practice" against the robot, it uses some moronic "dictionary" that other online games now use, including acronyms, proper names, and lots of typically unacceptable words. Take care!

What does the "Al" mean in the second score shown?
