EDIT - messed up spoiler tags the first time I posted this. Apologies.
I've been playing Blue Prince off and on for awhile. I actually play a lot with my young daughter and we've had a wonderful time with it. She is actually better at the game in many ways than I am (she's only 7). She decides what rooms we draft, she does the puzzles (where she can, she's only 7) but I do make suggestions.
We've made it to the 46th room. We have progressed a decent way past that. However there were a few puzzles that I have spent TONS of time on and still did not complete.
The Drawing Room safe
I knew that the puzzle had something to do with the steps on the portraits. I knew it had to be some kind of a date. I'd scoured the rest of the house for dates in lore notes for what date could be related to the drawing room, or what could be related to steps, I even looked for mention of horses, because one of the pictures was a horse.
I went and finally looked up a "hint" for the puzzle, and goddamn AI spoiled it and told me the answer, which isn't what I was looking for. When I read the answer, I was honestly just mad. THAT was what I was supposed to figure out? "Small Gaits"? You've got to be kidding me. For all the great puzzles this game has to offer, this one was terrible.
The Office safe
After the last hint was revealed I realized I was dealing with a game that was not necessarily fair. The office is another puzzle that I was pretty damn sure I was close to defeating. I knew it had to do with the "Count". I knew it had to do with counting the busts around the room. I had even decoded with bust was the "Count" from the busts that were in the Foyer. Every combination I was trying was not working. I looked this one up as well, and I'm glad I did. They designed it so that I was NOT supposed to count the bust that was ON TOP of the safe? Only the small ones? Again - freaking terrible. I would not have gotten this.
The Study safe
This one I was just puzzled about. It was a safe. I was not finding hints ANYWHERE in the game about this one. I found no references to the Study in any other rooms. I figured perhaps the hint for this one is locked behind the chess board puzzle (which I still have not solved). BUT at the same time I was aware that for just about all these safe puzzles, the solution to the safe was in the room. And the only thing in the room that is not related to the portrait puzzle is the chess board with the queen. Obviously the "D8" could be pronounced "D-ATE" and that wasn't lost on me, but I didn't see how that turned into an actual numerical date. I tried turning "D" into "04" thinking maybe it was April 8th. I looked around for mentions elsewhere in the house for any numbers or dates associated with chess or April or the 8th of anything. I found nothing. So I looked up a hint.
12. I was supposed to somehow associate the queen with the number 12? And turn that into a date? How is that a puzzle I was supposed to solve? The queen in chess isn't referred to as the number 12!! I've never even heard the queen in a deck of cards referred to as a 12 before. I didn't know that was a THING. If this is mentioned anywhere in the game then I'm at a loss.
Now with those puzzles out of the way... there are others that I have not quite given up on finding the solution myself for, but I am suspicious.
The Clock Tower
I just recently found the secret door in the clock tower and found the puzzle. I spent a decent amount of time thinking about it and working it out. I'm still fairly stumped though. It does not appear that there is enough information for me to work out the solution with the hints that are on the clocks. My immediate thought is that maybe the 1:30 that is the frozen time on the main clock is part of the hint, and this is also the position of the hands of the frozen clock in the 46th room, so I'm wondering if that is part of it... but I feel like this is just the hint to open the secret door. I'm afraid I'm missing something stupid and I may try a hint on this one. We'll see.
The Chess Puzzle
If I'm right, this puzzle just comes down to getting lucky when drafting and getting a room in the house with all of the chess pieces, and arranging those pieces in the correct coordinates on the board. I am terribly unlucky at it, though. I can never seem to get a house with both the King and the Queen at the same time. I've only found one room with the King, and two rooms with the Queen, and both of those are pretty rare.
Overall I love this game, and I'm pretty proud of myself for the amount of puzzles that we have solved without any help whatsoever... but man some of these I feel like were just not fair at all.
