           | afaik, guessing anything not 00000 or 11111 at first step

           | introduce possible "right digit at wrong place" as a third
           | state.
           | 
           | guessing 00000 or 11111 removes that third state and leaves
           | you with simple substitution of wrong cells, which leads to
           | an optimal 2 step strategy.
           | 
           | but obviously the shortest strategy is just guessing it right
           | on the first try :D lol

               | I have no idea in practice. But for the thermodynamic
               | limit of actually making a difference, any irreversible
               | change requires heat to be generated, e.g. initializing
               | to zero, truncating, or bitshifts with discarded
               | information. In contrast,
               | addition/subtraction/multiplication/bitshifts without
               | over-/under- flow will not necessarily generate heat.

       | 
       | That's still probably solvable with superpermutations but wordle

       | I also made some number-based wordle-variants, which I call
       | "numberdle". I found that it was hard to come up with good ways
       | of guessing because wordle has the restriction that _most_
       | combinations are invalid. You won 't ever have to guess xwqqf,
       | because that's not an English word. And more importantly,
       | guessing some letters gives you information about the other
       | letters. If you find out three letters, and have the target as
       | _a_ts, you can use that to figure out the other two letters.
       | 
       | But if you need to guess a number, and you know it's _5_34,
       | having three correct digits don't help you figure it out.
       | 
       | So I made some variants where guessed values _do_ help you figure
       | out the correct answer.
       | 
       | In rationerdle (https://zck.org/numberdle/?variant=rationerdle),
       | you have to guess a rational number x/y, where both x and y are
       | between 1 and 99, inclusive. It displays the rational number you
       | actually guessed, and whether x and y separately are too high or
       | too low.
       | 
       | In factordle (https://zck.org/numberdle/?variant=factordle), the
       | player has to guess the factors of a target number.
       | 
       | In formuladle (https://zck.org/numberdle/?variant=formuladle),
       | there is a graphed straight line, and the player has to guess the
       | mx+b formula that graphs that line.
       | 
       | I would like to make more, but didn't have any other great ideas
       | when I ran out of interest.
