About

River Drift

Read full description

Connect the pipes and guide the water from the source to the goal. 50 levels across five biomes. Place and turn the pipe pieces. There is no timer. The game can run offline. Each biome has its own unique challenges. Every biome looks different, and a slow soundtrack runs under all of them. The biomes are grass, forest, desert, old ruins, and a volcano. If you like connect puzzles, pipe and water games, or a calm logic puzzle, this is that.
