What is Order Detective?

Order Detective is a free visual logic puzzle by QuickRiddle. Place three to five neighbors in a row of houses so that every clue is true. Journey mode has 12 levels; Daily mode gives all players the same board for a given UTC date. No account or download is required.

How to play the ordering puzzle

  1. Read the clues and number the houses from left to right.
  2. Select a neighbor card and then a house, or drag the card onto a house. Moving a placed neighbor into an occupied house swaps the two.
  3. Fill every house, then select Check order. Any unsatisfied clues are marked so you can revise your arrangement.
  4. Use Undo to reverse a move. A first hint highlights a clue; the next hint reveals one placement. Solve without hints for a more demanding challenge.

Ordering logic puzzles with answers: three practice cases

Work from easy to harder cases below. Each person occupies exactly one house, every house is occupied, and positions run from left to right. These untimed practice puzzles are separate from the daily board. Keep the answers closed until you have an order that satisfies every clue.

Easy: a three-house logic puzzle

Mia, Ben, and Ava each live in a different house. There is exactly one house between Mia and Ben. Ava lives to the left of Ben. What is the order from left to right?

Reveal the order and reasoning

Mia, Ava, Ben. With only three houses, Mia and Ben must occupy the two ends to have one house between them. Ava therefore lives in the middle. Because Ava is left of Ben, Ben must occupy the right end, leaving Mia at the left end.

Medium: four neighbors in a row

Ava, Ben, Cleo, and Dan live in four houses. Who lives where?

  1. Ben lives immediately to the left of Ava.
  2. Cleo lives immediately to the right of Ava.
  3. Dan lives somewhere to the left of Ben.
Reveal the four-house solution

Dan, Ben, Ava, Cleo.

  1. The first two clues make an unbroken block: Ben, Ava, Cleo.
  2. That block can start only in house 1 or house 2.
  3. If it starts in house 1, Dan must occupy house 4, contradicting the final clue.
  4. Start the block in house 2 instead. Dan takes house 1, and every clue is satisfied.

Harder: five houses and a distance clue

Mia, Leo, Ava, Ben, and Zoe each occupy one of five houses.

  1. Ava lives in the middle house.
  2. Leo lives immediately to the left of Ava.
  3. Mia lives to the left of Ben, with exactly two houses between them.
  4. Zoe lives somewhere to the right of Ben.
Reveal the five-house solution

Mia, Leo, Ava, Ben, Zoe.

  1. Ava occupies house 3, so Leo occupies house 2.
  2. Two houses between Mia and Ben means their house numbers differ by three. In left-to-right order, they must use houses 1 and 4 or houses 2 and 5.
  3. Leo already occupies house 2, so Mia takes house 1 and Ben takes house 4.
  4. Zoe takes the remaining house 5. She is to the right of Ben, confirming the final clue.

How to solve ordering puzzles without guessing

Start with fixed positions, such as the middle house. Next, join immediate-neighbor clues into blocks. For a distance clue, list the possible house pairs before placing anyone. Finish by checking every clue against your complete order, not just the last clue you used.

Be careful with direction: "left of" does not mean "immediately left of." Also, two houses between two people means a gap of three positions, not two. If two orders still fit, look for an unused clue rather than assuming the answer.

Understanding the clues

To the left of
The neighbor has a lower house number, but does not necessarily live immediately next door.
Next-door neighbors
The two people occupy adjacent houses, in either order unless another clue fixes their direction.
One house between
Their house numbers differ by two. For example, houses 1 and 3 satisfy this clue.

Order Detective questions

Does each puzzle have one answer?

Yes. The generator tests all possible orders against its clues and adds constraints until exactly one order remains.

When does the daily puzzle change?

The daily board is based on the UTC date at page load. Reload after 00:00 UTC to start the new day's challenge. Players opening the same UTC date get the same puzzle.

Where are scores and streaks saved?

Completed-level records and daily streaks are stored in this browser on this device. They are not a global leaderboard and do not sync between devices. Clearing browser storage removes them.

Does sharing reveal the answer?

No. Copy result includes the case or date, time, checks, hints, and game link, but not the neighbor order. Journey links open the same case for your friend. Daily links open the current UTC day's puzzle, so compare daily results from the same date. On supported devices, Share challenge opens the system sharing menu.

Can I play on a phone?

Yes. Tap a neighbor, then tap a house. The game supports English, simplified Chinese, traditional Chinese, and Thai, with light and dark themes.
