A way in
Play the opening rounds before reading ahead. When the controls appear, change one condition at a time and make a prediction before running the model.
Free browser game built around reading and repeated choices. The creator lists fan translations and a 30-minute playing time. No account or payment is needed to begin; the source page does not describe keyboard-only or mobile controls.

Why we chose it
You begin by choosing whether to cooperate. Soon you watch different ways of playing compete over repeated rounds, under rules you can inspect and alter. Somewhere along the way, your one choice has turned into a system you can watch run. You can ask what the setup rewards before reading any outcome as a verdict on character. The model is deliberately small; its omissions matter alongside its results.
