Trapdoors

How to play

1. We asked AI models the same question several times. Each door is one answer they gave; one more door says none of them is right.
2. Each round, spread 10 bundles over the doors. Each bundle is a tenth of your points, and you can put all 10 on one door.
3. Lock in, and trapdoors open under the wrong doors. Only the bundles on the right door carry on to the next round.
4. Spreading your bundles by how sure you are keeps the most points over many plays; going all in pays only when you're right.
5. Five rounds and 1,000 points to start: points, not money. Nothing is random: what is right in each round was settled before you play.
6. Drop to zero and your score is 0, but you carry on with a practice stack of 1,000 to see the rest.

Every answer here is a real recorded run, labelled with its model and date. Your moves stay on this page: we count only plays, results and link clicks, without cookies.
