# River

This group of tasks requires the agent to cross a river using boulders and reach the goal located on the other side. Boulders, when pushed into water, create a dry land to walk on, allowing the agent to cross it.

While the MiniHack-River-Narrow-v0 task can be solved by pushing one boulder into the water, other MiniHack-River-v0 require the agent plan a sequence of at least two boulder pushes into the river next to each other. In the more challenging tasks of the group, the agent needs to additionally fight monsters (MiniHack-River-Monster-v0), avoid pushing boulders into lava rather than water (MiniHack-River-Lava-v0), or both (MiniHack-River-MonsterLava-v0).

Examples of the MiniHack-River-v0 task:

## Reward

The agent receives a reward of +1 for reaching the goal.
