Trolley Game
Trolley Game lets you make difficult choices and find out how well AI can predict them. You can share a game with a friend, too, if your friendship could use a small philosophical stress test.
I came across Neal Agarwal’s Absurd Trolley Problems years ago and loved how thoroughly it abused a respectable philosophical exercise. In the summer of 2026, I started wondering what would happen if the dilemmas felt a little closer to real life.
I made two sets: High Stakes, where lives are on the line, and Social Stakes, where you’re dealing with relationships, privacy, and work. The second set doesn’t need a body count to make a choice difficult.
It thinks it knows you
First, you answer a few playful warm-up questions. The AI uses those to guess how you’ll answer the dilemmas and locks in its predictions before you make your choices. Then you play and see how well it read you.
You can also share a game with a friend. Once they’ve finished, you can see each other’s answers and compare where you agreed, where you didn’t, and which answers need a conversation.
I used AI to build the game mechanics, imagery, and sound, including countdowns to add a little pressure while you decide. It’s free to play. After sharing it with a handful of people, I started wondering what different AI models would choose for themselves. That became a separate study.
