500 Rooms wins Rep. David Valadao’s 2023 Congressional App Challenge in California’s 22nd District

Rep. Valadao has named Eli Cobine, a 10th grader at Hanford West High School, as the winner of the 2023 Congressional App Challenge in California’s 22nd District.

When asked what inspired the creation of 500 Rooms, the student said, “Video games, mostly. Other dungeon crawler games were fun to play, and I decided to try and make one of my own. Other than video games, Khan Academy was a huge inspiration. There’s a coding community (called the KACC, the Khan Academy Coding Community), and there are amazing projects that other people have created using coding, the same way that I did. Khan Academy also taught me how to code. All of my knowledge on coding is thanks to Khan Academy.”

This year’s Challenge saw an unprecedented level of participation, with 374 Members of the House of Representatives hosting competitions, surpassing the previous record of 340. A remarkable 11,334 students from across the United States competed in this year’s Challenge, marking an impressive increase of nearly 1,000 participants compared to the previous record set in 2019. The enthusiasm and creativity these students display is a testament to the growing interest in technology and signal a bright future for American innovation. The surge of ingenuity continued with a whopping 3,645 original applications flooding in, nearly a thousand more than the previous year’s high. This remarkable growth showcases the exceptional talent and innovation within our nation’s youth.


The Congressional App Challenge is an official initiative of the U.S. House of Representatives, where Members of Congress host contests in their districts for middle school and high school students, encouraging them to learn to code and inspiring them to pursue careers in computer science. This resounding show of bipartisan support emphasizes the critical importance of STEM education in today’s rapidly evolving world. Each participating Member of Congress selects a winning app from their district, and each winning team is invited to showcase their winning app to Congress during our annual #HouseOfCode festival. The program is a public-private partnership made possible through funding from Omidyar Network, AWS, Rise, theCoderSchool, Apple, and others.

The 2024 Congressional App Challenge will launch in May of 2024, and eligible students can pre-register for the competition now.
