SPIN Protocol

SPIN Protocol is a beam reflection puzzle game about rotating nodes to guide and mix color signals. Emitters send color signals that need to be redirected to activate all the receivers using the various nodes at your disposal. SPIN Protocol expands on the classic laser puzzle formula to offer a moderately original experience.

While the first chapter of SPIN Protocol is pretty straightforward to teach the basics, subsequent chapters each add complexity and depth to the game. At first, two colored signals going through the same node just cancel each other out, none can exit. However a new node is introduced later on to allow color mixing, which is used in surprising ways sometimes. Combined with blank emitters that store the last color received, you can already imagine how knotty the routes can get.

Finding the correct path is not always the hardest part, especially after security nodes are introduced. These special nodes carry sensors that you must never activate, or else the level resets immediately. While they can usually be safely dealt with by thoroughly analyzing the level prior to manipulating other nodes, a few puzzles still lead to short action sequences and require rotating some nodes quickly enough.

Completing a puzzle grants a star, more of them can be gained through challenges such as clearing the puzzle under a time limit and under a fixed amount of rotations. The stars you get not only unlock new chapters, but also secret levels once you gather all the stars of a chapter.
