Wonderful catches on all of these. I'll try and rework them sometime. Could you explain this one though, I am kinda lost where you see the other solution in the 25th puzzle.
Right. Splendid job. These T's are quite the pick to work with. You clearly know your stuff, so I'll ask you, do you think I should scrap the T, offer multiple solutions or invent a symbol which allows numbers to be in a quantum state between values, or something else? I am quite new to making puzzles (this is my first time), so I am clueless. Much appreciated for all the work done so far. By the way, to make my life easier, I've written a python program to find all alternate solutions to the T problems. Quite eye opening, want the script?
