About the game

What you do in a play session

Have you ever wondered how Sherlock Holmes manages to deduce everything so quickly? In Orapa Street 221b, you get the chance to prove that your brain is just as sharp as the world's most famous literary detective. This game is a direct evolution of the concepts seen in Orapa Mine, bringing a spatial deduction challenge that will test your wits in a truly fun way.

The goal is easy to grasp but hard to master: each player hides 'reflective' elements on their private player board, which is made up of a grid of triangles. The key twist is that you need to discover the exact location and color of your opponents' hidden elements. To do this, you fire 'laser signals' and observe how they reflect and what colors they become during the process. It's a constant exercise in logic; every signal you send is a piece of the puzzle falling into place, revealing a bit more of your neighbor's secret layout.

The gameplay experience is all about observation and deduction. You need to be methodical, tracking every result of your shots to avoid getting lost in the complexity of the trajectories. It's the kind of game that demands focus and concentration, perfect for those who love solving mysteries and seeing logic prevail over luck. Interaction happens indirectly, as you try to unravel others' secrets while protecting your own. If you enjoy games that make you feel like a true detective, using pen and paper to map out the unknown, Orapa Street 221b will be an absolute hit at your table. Grab your magnifying glass, sharpen your pencil, and get ready for an intense intellectual hunt where every move counts.
