MSRP has ended

Due to eBay API restrictions, MSRP is no longer able to generate new daily games. You can still play past games using the menu above. The site will remain available until it goes dark sometime next March.

Check out savantle.com for a similar daily game based on Baseball Savant percentiles, or polyloon.com for other projects.

I'm also building a new game called Calibration. Each day you get five real facts, like a building's height or a country's population, and instead of guessing one number you guess a range. The tighter and more correct your range, the higher you score. Play it at calibrationgame.app.
