Listed

A property listing with the price torn off. Listed shows you one photo, the date the place sold, and a spec sheet where every value is hidden behind a row of x characters, then gives you eight guesses at what it went for. The masked sheet is the game's signature: Location, Property Type, Beds, Baths, Built, Sqft, Lot Size, List Date, List Price, all sitting there in plain sight with their answers blacked out, unmasking one row at a time as you get things wrong. The daily has stopped, but nothing has been taken down. The archive rolls on from three shuffle buttons on the front page, and it is still the same game it was.

1. Study the photo and the sold date before you commit. That date is the only unmasked field on the board and it sets the market you are pricing into.
2. Type a figure and press GUESS. The field takes a plain number.

Listed had the best interface of any price-guessing game and it is still standing. The masked spec sheet turns each wrong guess into a small transaction, you pay a guess and you buy a fact, and the fixed reveal order means the difficulty is authored rather than random. That it has stopped publishing new puzzles matters less than it sounds, because the archive is deep, free, open without an account, and shuffled with one click. The end screen linking through to the genuine listing is the last nice touch: you can always go and look at the house that just made a fool of you.

Five symbols, and the two diagonals are the ones that matter. A full up or down arrow means you are a long way out and should move in big steps. A diagonal up or down means you have crossed inside 10% or $10,000 and should stop swinging. A little house icon means you have landed inside the winning band, which is 1% or $5,000. Every guess stays on the board numbered and formatted in dollars, so the bracket you have built is always visible. When the eighth guess is spent the game names the sale price, hands you a See the listing link to the real record, and offers SHARE and ANOTHER GAME. One archive property was listed at $599,000 in Colcord, Oklahoma and sold for $515,000, which is exactly the trap the last hint is designed to spring.

Listed USA

The general archive, anywhere in the country. Eight spec rows including lot size, which on a rural listing can be the single most important line on the board.

Listed San Francisco

A city edition with its own numbered archive. The board drops the Lot Size row entirely, so you are pricing on square footage, year built and neighbourhood alone.

Listed Chicago

The other city archive, shuffled from the same header menu.

• Do not treat the list price as the answer. It is the eighth and final reveal, it arrives when you have one guess left, and it is an asking price, so it can sit well above what the place actually fetched.
• Spend guess one deliberately wide. The reveal order is fixed and Location is first, so your opening bid is really just the price of finding out which state you are in.
• The moment an arrow goes diagonal, halve your step. That symbol is a hard signal that you are inside 10% or $10,000, and the winning band is only 1% or $5,000 wide, so big moves from there throw the game away.
• On a low-priced house the dollar allowances do the heavy lifting. Under about $500,000 the flat $5,000 window is wider than 1%, which quietly makes cheap rural listings more forgiving than expensive city ones.
