Hi! I've been working on a new kind of logic puzzle. It's called Ringoku and there's a new one every day.

The rules fit in two lines:

1. Each of the 4 rings holds the numbers 1 to 8, no repeats.

2. Touching pieces can never hold the same or consecutive numbers (a 4 can't touch a 3, a 4 or a 5).

The rings are offset like bricks, so every piece touches 6 others, which is where the logic gets interesting. Every puzzle has a single solution and can be solved by pure reasoning, no guessing.

- Easy on Mondays, harder every day until Sunday

- 3 lives and 3 smart hints

- Free, no ads, no sign-up, works on mobile

- English and Spanish

It's brand new, so I'd really love feedback: was it clear how to play? Too easy, too hard? Anything annoying?

Each pair of numbers maps to the number below it by a consistent hidden rule. Use the known examples to find the pattern, then solve for the missing output. Game: Rule Hunter — https://play.google.com/store/apps/details?id=com.makenumber

This one is a significant step up in difficulty over the last couple!

Someone knocked the vase over. Four witnesses were in the room: the Lookout, the Kid, the Neighbor and the Dog. Each says what they saw.

You're not finding who did it, just who's lying about what they saw.

Your goal: find the one witness who is lying.

Difficulty: 7/10

THE ROOM (5 by 5, columns A to E, rows 1 to 5)

• Sneakers on B1 (flat)

• Teddy bear on C2 (flat)

• Vase on B3 (low)

• Clock on A4 (tall)

• A wall runs between columns C and D, along rows 2 to 4

• A wall runs between rows 2 and 3, under columns B and C

THE RULES

• Each witness stands on their own empty square. People never block a view.

• Tall things and walls block every view. Low things block only the Kid. Flat things block nothing.

• The Lookout sees their whole row and column.

• The Kid sees their whole row and column too, but low things also block them.

• The Neighbor sees 2 squares in all 8 directions, diagonals too.

• The Dog can't see, but smells the 8 squares around it, through anything.

• "I didn't see X" means X really wasn't in their view.

• Honest witnesses only say true things. The liar says at least one false thing.

• There may be more than one way to place everyone. The liar is the same in every one.

WHAT THEY SAY

• The Lookout: "I saw the vase. I saw the Kid. I didn't see the Dog."

• The Kid: "I saw the teddy bear. I didn't see the Neighbor. I didn't see the Dog."

• The Neighbor: "I saw the sneakers. I saw the Kid. I didn't see the Dog."

• The Dog: "I smelled the teddy bear. I smelled the vase. I didn't smell the Lookout."

Exactly one of them is lying. Who?

Please mark your answer as a spoiler so others can still solve it.

I adapted these rules from a puzzle game I'm making, Lie of Sight.

I brought my self-made puzzle board with cute number characters to the park and set it up on a bench!

Can you arrange these numbers back into the HOME layout (1 to 9) in just 3 moves?

Current Board Setup:

[ 5 ] [ 9 ] [ 6 ]

[ 7 ] [ 3 ] [ 8 ]

[ 2 ] [ 1 ] [ 4 ]

🧩 Rules:

1. Your goal is to reach the 1-9 HOME layout within the given moves.
2. Tap a number tile to keep it fixed in place while the remaining 8 tiles rotate clockwise around it.
