Definition
Plain language
A grid-navigation puzzle deliberately rigged so a robot can't succeed without first exploring to learn the hidden controls.
As stated in the literature
A FrozenLake variant where action labels are randomly shuffled and hidden per map, imposing an information-theoretic wall that forces an agent to explore and record the mapping before it can exploit it.
Why it matters: By hiding the controls, it forces an agent to actually explore and remember what it learns rather than coasting on memorized answers.
For example, an agent doesn't know whether the 'up' button moves it up or sideways until it tries a few moves and watches what happens.
