Build railways. Solve puzzles. Deliver cargo.

Guide colored cargo containers to their final destination by building railways through a voxel world of islands, deserts and mountains. Each handcrafted puzzle introduces new ideas and gradually expands on what you’ve learned. As the challenges grow, you’ll build multi-level bridges across the ocean and over great heights, tunnel to reach uncanny valleys, and find your way through increasingly intricate layouts. Intuitive track-building mechanics make it easy to build rail, while carefully designed puzzles provide satisfying challenges that reward observation and logical thinking. Watch your solution come to life as trains collect, transport, and deliver thousands of cargo containers to their ultimate destination - or get mixed up into oblivion.

Handcrafted Puzzles

Every puzzle is carefully designed to present a new challenge with new mechanics introduced gradually, combining to create increasingly rich and satisfying railway conundrums.

Intuitive Rail Building

Simple railway tools allow for easy building while supporting complex rail systems with tunnels, stacking bridges and myriad ways to connect and interconnect your routes. 

Train Traversal

Carefully route your trains to untangle mixed up cargo with train scheduling, routing and filtering of cargo. Trains will try not to crash - but anything's possible!

Build Across 3D Worlds

The landscape is integral to every puzzle. Traverse the ocean with bridges, tunnel through mountains and fully harness the third dimension to reach new heights.
