Solution

The answer was: >!Kitchens!<

Solution: Part 1: >!the word blindly, along with the 2×3 pattern of each colour, hints at braille. Find the colour that has the most correct in each question, and treat a correct country as a positive and wrong country as a negative to get a braille letter for each colour. This will give you “St Mungo's“!<

Part 2: >!Find the film each synopsis is hinting at, then find out what letter changed to change a word and the meaning of the title. Use the new letters to spell out “kitchens“!<

Note: “Arithmancy Points” are not the same as House Points. House Points will be awarded at the end of the month based on the combined total of “Arithmancy Points” earned.

Level 3

“Oh yes. It is a copy — an excellent copy, it is true — but it was Wizard-made. The original was forged centuries ago by goblins and had certain properties only goblin-made armour possesses. Wherever the genuine sword of Gryffindor is, it is not in a vault at Gringotts bank.”

Good luck and remember that the theme this month is Locations!

Welcome back for the fifty-seventh month of r/Arithmancy! For those of you who are new, welcome to the Harry Potter puzzle subreddit where the students of Hogwarts are asked to work with their houses to decipher clues in order to practice their Arithmancy and curse-breaking skills.

Fill out this form if you would like to sign up for notifications when new puzzles or announcements are posted.

Puzzle Creators Wanted!

Are you interested in creating puzzles, but you don’t want to commit to joining the Arithmancy Professors? Check out our Prefect FAQs our Prefect Guide or our new Prefect Schedule!

Instructions for how to submit your puzzle can be found in the #links-and-resources channel on Discord.

If we choose your puzzle to use, you will be given a special Prefect role in Discord that allows you to talk to the professors while your puzzle is being solved, and to prevent you from helping your House during the puzzle. This is an awesome opportunity to test out being an Artificer without committing, too.

Feedback

We would like to hear your feedback about r/Arithmancy and your suggestions for making it better. Share your thoughts about the types and difficulty of puzzles, the hints system, the points system or anything else you think of below! What did you like about last month's puzzles? What did you dislike? Do you think changes should be made to make it more fun or fair for all houses? Comment below or use our anonymous feedback form.

January Schedule

The theme this month is: Locations!

Each level will last 48 hours and there will be a break between each level. The puzzles will be posted on r/Arithmancy and a link to the puzzle will be posted on Discord. The fourth puzzle each month is balanced for beginners, and isn’t worth points.

Hints will be given in the private channels on Discord upon request. Tag @hint if your house is stuck and needs a hint to proceed. All hint requests will be logged in the #room-of-requirehint channel on Discord.

There will be 4 levels this month:*

*Schedule is subject to change.

How to participate

Puzzles should only be discussed in your house's Arithmancy Discord channel* and your house common room. If you would like to join your house’s common room, check here for instructions.

Links to the Reddit threads with your house’s Discord invite link: Gryffindor, Hufflepuff, Ravenclaw, Slytherin (Note that you can only open these if you are a part of your house’s common room.)

A link to the submission form will be included with each puzzle posted. Each student may submit only ONE guess per level and may have only one Reddit account used for participating. You may only submit for your own house.

If you are caught breaking these rules, you will be removed from the game.

##Points

Here is the entirety of the points calculations as they stand:

Points will be awarded based on the speed of each house to solve each puzzle, and based on the number of hints they use to solve it. All 5 hints will be available for the duration of each puzzle, and for each hint they request, the hint bonus will be decreased accordingly:

• 0 hints - 40 point bonus
• 1 hint - 38 points
• 2 hints - 35 points
• 3 hints - 31 points
• 4 hints - 26 points
• 5 hints - 20 points

Houses will also be awarded a number of points based on how quickly they solve their puzzle as follows: an inverted sigmoid function, 5 / ( 1 + e^(10x/a-5) ) where a is the amount of time it took for the last house to solve the puzzle, will be used to calculate the bonus each house gets for their speed, relative to the speed of the other houses that solved. Here's a link to an interactive graph on Desmos, where you can see the resulting curve. This bonus has a maximum of 5 points.

There will also be a tiebreaker added to every score based on the order of who solves first. First place will earn 4 points, second: 3, third: 2, and fourth: 1 point.

Each house’s score will be calculated using Hint Bonus + Speed Bonus + Tiebreaker = Final Score

House points will be awarded at the end of the month, based on how many Arithmancy Points each house earned in total. House point calculations are based on the new proposal in HP Meta.

Level One

Bathilda was tottering around the place lighting candles, but it was still very dark, not to mention extremely dirty. Thick dust crunched beneath their feet, and Harry’s nose detected, underneath the dank and mildewed smell, something worse, like meat gone bad. He wondered when was the last time anyone had been inside Bathilda’s house to check whether she was coping. She seemed to have forgotten that she could do magic, too, for she lit the candles clumsily by hand, her trailing lace cuff in constant danger of catching fire.

“Well,” said Slughorn, not looking at Riddle, but fiddling with the ribbon on top of his box of crystallised pineapple, “well, it can’t hurt to give you an overview, of course. Just so that you understand the term. A Horcrux is the word used for an object in which a person has concealed part of their soul.”

Solution

The answer was: >!Amortentia !<

Solution: Part 1:

!Part 1 was seven segment display. The different segments are labelled a-g, and if you took each of the books the quotes were from (in the three paragraphs) and A1Z26 them, they'd give you 633. Page 633 of HBP, the month's theme, gave the chapter name The White Tomb, which is the answer!<

Part 2:

!Use the years provided to figure out which films to use. All of them had a character played by the amazing Dame Maggie Smith. Indexing the first names of the characters played by Maggie Smith in the chosen films gave an anagram of amortentia.!<

Level One

Crookshanks trotted after her, his yellow eyes fixed upon Arnold. Harry turned away from Ron, who did not look like he would be surfacing soon, just as the portrait hole was closing. With a sinking feeling, he thought he saw a mane of bushy brown hair whipping out of sight.

Welcome back for the fifty-fifth month of r/Arithmancy! For those of you who are new, welcome to the Harry Potter puzzle subreddit where the students of Hogwarts are asked to work with their houses to decipher clues in order to practice their Arithmancy and curse-breaking skills.

Fill out this form if you would like to sign up for notifications when new puzzles or announcements are posted.

Puzzle Creators Wanted!

Are you interested in creating puzzles, but you don’t want to commit to joining the Arithmancy Professors? Check out our Prefect FAQs our Prefect Guide or our new Prefect Schedule!

Instructions for how to submit your puzzle can be found in the #links-and-resources channel on Discord.

If we choose your puzzle to use, you will be given a special Prefect role in Discord that allows you to talk to the professors while your puzzle is being solved, and to prevent you from helping your House during the puzzle. This is an awesome opportunity to test out being an Artificer without committing, too.

Feedback

We would like to hear your feedback about r/Arithmancy and your suggestions for making it better. Share your thoughts about the types and difficulty of puzzles, the hints system, the points system or anything else you think of below! What did you like about last month's puzzles? What did you dislike? Do you think changes should be made to make it more fun or fair for all houses? Comment below or use our anonymous feedback form.

October Schedule

The theme this month is: HP HBP!

Each level will last 48 hours and there will be a break between each level. The puzzles will be posted on r/Arithmancy and a link to the puzzle will be posted on Discord. The fourth puzzle each month is balanced for beginners, and isn’t worth points.

Hints will be given in the private channels on Discord upon request. Tag @hint if your house is stuck and needs a hint to proceed. All hint requests will be logged in the #room-of-requirehint channel on Discord.

There will be 4 levels this month:*

*Schedule is subject to change.

How to participate

Puzzles should only be discussed in your house's Arithmancy Discord channel* and your house common room. If you would like to join your house’s common room, check here for instructions.

Links to the Reddit threads with your house’s Discord invite link: Gryffindor, Hufflepuff, Ravenclaw, Slytherin (Note that you can only open these if you are a part of your house’s common room.)

A link to the submission form will be included with each puzzle posted. Each student may submit only ONE guess per level and may have only one Reddit account used for participating. You may only submit for your own house.

If you are caught breaking these rules, you will be removed from the game.

##Points

Here is the entirety of the points calculations as they stand:

Points will be awarded based on the speed of each house to solve each puzzle, and based on the number of hints they use to solve it. All 5 hints will be available for the duration of each puzzle, and for each hint they request, the hint bonus will be decreased accordingly:

• 0 hints - 40 point bonus
• 1 hint - 38 points
• 2 hints - 35 points
• 3 hints - 31 points
• 4 hints - 26 points
• 5 hints - 20 points

Houses will also be awarded a number of points based on how quickly they solve their puzzle as follows: an inverted sigmoid function, 5 / ( 1 + e^(10x/a-5) ) where a is the amount of time it took for the last house to solve the puzzle, will be used to calculate the bonus each house gets for their speed, relative to the speed of the other houses that solved. Here's a link to an interactive graph on Desmos, where you can see the resulting curve. This bonus has a maximum of 5 points.

There will also be a tiebreaker added to every score based on the order of who solves first. First place will earn 4 points, second: 3, third: 2, and fourth: 1 point.

Each house’s score will be calculated using Hint Bonus + Speed Bonus + Tiebreaker = Final Score

House points will be awarded at the end of the month, based on how many Arithmancy Points each house earned in total. House point calculations are based on the new proposal in HP Meta.
