About this game

River Crossing is a logic puzzle where you move animals across the river without leaving predators alone with prey. It rewards planning, sequencing, and careful decision making under constraints.

NeuralPrep includes free starter levels as well as more advanced Pro levels with added mechanics such as safe pairs, heavy animals, and environmental restrictions.
