Bottom of the 9th. Bases loaded. Two outs. And our pitcher just… keeps missing the zone. Ball after ball after ball. I was watching a KBO game, yelling at the screen, and eventually that frustration turned into: “You know what? I’m making a game where you have to throw strikes.” So I did. Put the Ball in the Square is a mobile web mini-game where you play as a pitcher trying to hit the strike zone. You stop a moving bar inside the green zone to throw a strike. Get 3 strikes, and you win the inning. Throw 4 balls, and it’s game over — you’ve let everybody down. The twist? Every pitch gives your pitcher a random debuff: hungover, stomach issues, the flu, gambling debt, family drama… all the things that might explain why he suddenly can’t throw a strike. Each debuff messes with your timing and accuracy, so even a simple pitch can spiral fast. How I built it Built the whole thing with AI (Claude), going from pure rage to a playable game React + TypeScript Mobile-first web app No install needed — just open the link and start pitching Supports both English and Korean It’s free, has no ads, and runs right in your phone browser. It’s still a work in progress. There’s no sound yet, and the visuals and features are still pretty rough in places, but I’m actively improving it based on feedback. Sound, better polish, and more features are all on the roadmap. If you’ve ever yelled at your TV because your pitcher couldn’t find the zone, this game is for you. Now you get to feel that pressure.
