Players of Stack Road navigate a grid of interlocking blocks, rotating them to create ascending paths for a rolling set of objects. The blocks are interconnected, and players must rotate them to clear a path for the objects to advance upwards.
The main goal is to move the objects up the grid by cleverly arranging the blocks, all without any block touching another in the up-down direction. The game runs directly in a web browser, with no need to download or register.
