My Sporcle Quizzes

In my middle school years, I used to play many quizzes on Sporcle, arguably the world's largest quiz/trivia website. I've made some quizzes of my own, 2 of which I would like to share in this post.

Number Logic Puzzle

Please go play the quiz here and like and comment!

How to play: In a 3x3 grid, there are 6 numbers (1 - 6) and 3 bombs. Type the number or b for bomb. Adjacent DOES NOT include diagonals. This can be solved without guessing.

I created this way back on March 10th, 2018, but it was curator picked on January 12th, 2020!

Solution

From this very first hint, you know that since A1, B3, C1 and A2 contain numbers, they do not contain a bomb. More importantly, since A1*B3=C1*A2 and A1 = 4, 4*B3 = C1 * A2. Now, the only number that can be written as the product of two pairs of two unique numbers from 1-6 is $12=4*3=2*6$. Therefore, we can conclude that B3 must be 3.

Now, recall that C1 is a number. Since A1 is also a number (4), and this hint states that at least one corner contains a bomb, either A3 or C3 must contain a bomb. But read closely: all bombs are adjacent to at least one other bomb (adjacent excludes diagonals). This means that if A3 contained a bomb, then either A2 or B3 must also contain a bomb. But B3 is obviously 3, and recall that we also said A2 contains a number. This means A3 cannot contain a bomb, so C3 must contain a bomb.

Now, we have all the information we need to fill out the rest.

• Because all bombs are adjacent to at least one other bomb, there must be a bomb in C2, adjacent to C3.
• Again, because all bombs are adjacent, the last bomb must be adjacent to C2, at either B2 or C1. However, because the top row is in ascending order, the top row contains only numbers. This means the last bomb must be at B2.

• Now, we said that C1*A2 = 12 where C1 and A2 are 2 and 6 or vice versa. However, because the top row is in ascending order, we know automatically that the only way to fill it out the row if A1 is 4 is to have 4,5,6 such that B1 is 5 and C1 is 6.
• This means that A2 is 2
• Finally, A3 contains the remaining number, 1.

Chess Logic Puzzle

This is a logic quiz that requires knowledge of chess in order to solve. Combining two of my biggest passions!

How to play: A 3x3 contains 7 safe squares and 2 bombs. Adjacent INCLUDES diagonals.

Solution

The fact that a rook would be adjacent to both bombs means that the bomb must be B1, C1, A2, B2, C2, A3 or B3. This means that the C3 square must be safe.

This is fairly simple - if a bishop from C3 cannot land on a bomb, then the B2 square must be safe.

If a pawn can "capture" 2 safe squares (A1 and C1), then C1 must be safe.

Using the fact that the 2 bombs are not adjacent (including diagonally) and that the two bombs are not in the same row or column, we can deduce that A3 must contain a bomb. We conclude this by considering each square a bomb could be in - A2, B1, C2, A3 or B3.

• If the bomb was in A2, then the second bomb cannot be in C2 since it would share the row. But it cannot also be in B1, B3 or A3 since it would be adjacent. There is no possible square for the second bomb, so A2 cannot contain a bomb. This means A2 is safe.
• If the bomb was in B1, then the second bomb cannot be in B3 since it would share the column. But it cannot also be in A2 or C2 since it would be adjacent. Therefore, the second bomb would have to be in A3.
• If the bomb was in C2, then the second bomb cannot be in A2 since it would share the row. But it cannot also be in B1 or C3 since it would be adjacent. Therefore, the second bomb would again have to be in A3.
• If the bomb was in B3, then the second bomb cannot be in B1 since it would share the column. But it cannot also be in A2 or C2 since it would be adjacent. Therefore, the second bomb would have to be in A3.

Hence, we have just shown that A2 is safe and A3 contains a bomb.

Finally, if the other bomb is not in the row above A3, then it must be in B1, so C2 and B3 are safe. This completes the puzzle.

Hope you enjoyed the quizzes I made! I would like to get back to Sporcle and start making quizzes again. Stay tuned!
