HQ Trivia meets Zillow: This live real estate game is giving away houses

For many people, when a 'For Sale' sign pops up in their neighborhood, one of the first questions that comes to mind is: how much will that place go for? This price curiosity—fueled by house flipping shows on HGTV and doomscrolling on Zillow —has gone from idle neighborhood interest to multimedia obsession.
Now that experience is being turned into PropQwiz, a live daily trivia sweepstakes, and accurately guessing the listing price will give players a chance to win up to $350,000 to purchase a home, pay off a mortgage, or make a down payment.
Like a mix of the defunct daily trivia game HQ Trivia and the real estate listings on Zillow, PropQwiz is a live game played through an app that uses actual real estate listings to quiz players on the likely selling price of homes around the U.S.
Every weekday at 3 p.m. (Eastern Time), the PropQwiz app will broadcast a three-minute video featuring one house currently on the market, offering five clues about the home, the property, the amenities, and the location, and then giving players 15 seconds to guess the listing price. The closer the guess, the more points a player receives, and each point counts as an entry into a periodic sweepstakes for the grand prize of $350,000 toward a home, or $175,000 in cash. According to PropQwiz's rules, the first home giveaway will happen after the total number of plays on the daily game and other minigames within the app reaches 31 million. By comparison, HQ Trivia had 2.4 million concurrent users at its peak of popularity.
'The more people who play this game and the more games that are played, the more homes we get to give away,' says PropQwiz creator Jim Casey. 'In the beginning, it might be a home a month. We're looking to quickly turn that into a home a week, and perhaps even a home a day.'
A longtime television producer behind shows like Building Outside the Lines and The Dead Files, Casey says the idea for the game came from his own experience, walking his dogs in his Los Angeles neighborhood with his wife and quizzing each other on the prices of homes that were up for sale. 'It was fun in our neighborhood, but we found that when we traveled and we were in unfamiliar areas, it was even more fun,' he says.
That guessing game turned out to be a common one among Casey's friends, and as he looked into it, he realized that there is an even larger pool of people who browse real estate listings just for the fun of it. Research from 2021 found that more than a third of Zillow users were not actively in the market for housing but were just using the site casually. 'People were doing this everywhere,' Casey says.
But there's also a bleaker side to that stat, which is that many people are only casually looking at real estate listings because they can't actually afford to buy a home on the market. For people in the Gen Z and millennial age range, more than half believe they'd need to win the lottery to be able to afford a home, according to research from Zillow. 'So we thought, alright, let's give them a lottery, or at least a form of the lottery,' says Casey. (Legally speaking, the game is a sweepstakes; PropQwiz is free to play, and is supported by ads.)
Ahead of PropQwiz's first official live game on June 30, I tried my luck at a beta version of the game. I watched a three-minute video montage of a contemporary house while a narrator cheekily explained its stats and amenities: 5,200-square feet, five bedrooms, six bathrooms, walk-in pantry, saltwater pool, hot tub, all on three quarters of an acre. The final, and most important, clue—location, location, location—is that the home is in Charlotte, North Carolina. Not knowing much about that particular housing market, and likely not ever being in the market for such a big house, I used my 15 seconds of guessing time to frantically suggest a listing price of $7.8 million. Within seconds, the true price was revealed: $3.45 million.
'So you were pretty far off there,' says PropQwiz COO Daniel Tibbets.
'But that's okay,' he adds, noting that even a very bad guess—one off by multiple millions of dollars, for example—earns a player at least 100 points, or 100 chances to win. Somebody guessing closer to the $3.45 million mark would have racked up 5,000 points, vastly improving their odds of winning the ultimate sweepstakes.
In addition to the daily live game, PropQwiz also features what Casey and Tibbets call minigames, which are multiple-choice quizzes that show a home and as for its current listing price, or in a version called Time Machine, its price decades ago.
The homes featured in PropQwiz aren't pulled from real estate listing aggregators like Zillow and Redfin but licensed from real estate photographers across the country. 'They own the copyright on all these images,' Casey says. 'So we ask them what are your favorite homes?' The PropQwiz team digs through thousands of images to find good candidate houses. Casey, the longtime television producer, says they aren't always big expensive homes, but they do have to have some standout feature or unique quality. 'We always want something that people are going to enjoy taking a tour of,' says Casey. 'It needs to be something that's either very relatable or very aspirational.'
And, hopefully, entertaining enough that people tune in repeatedly, and get others to as well. 'You bring in more people to play, you play more games, you get to have fun playing a game, and we get to give away homes,' Casey says. 'That's the goal.'
