If it’s just a simple maze with no essential/blocks/whatever, we can use any path-finding algorithm to solve it. Ok, now that we have all the names available, we can delve into the algorithm. (This part will be expanded when more types of elements are supported in the solver) 2. A segment is formed by the solution path, and has to touch the border at least on one side. Judging from the game, tails can only be placed on the border, while there’s no restriction for heads.Įssential nodes and essential sides are represented by black hexagons, which need to be traversed exactly once with the solution path.īlack/white blocks have to be in different segments. Heads and tails are the start and end of a puzzle. (It’s possible to merge node map & block map into a single matrix, but I decide to keep them separated for simplicity’s sake.) These are just for storing the special blocks between nodes and sides, and it’s completely empty if we’re just dealing with a simple maze. On top of the node map, there’s also a block map. (BTW, the correct terms for them in graph theory are vertices and edges). The intersection is a node, while the short path between 2 nodes is a side. The node map consists of all the paths and their intersections. Skip this part if you don’t feel like reading encyclopedia. Since The Witness is entirely text-free, I have to come up with names for various elements of the puzzle. As more types of puzzle elements are supported, this article will be expanded accordingly.

The following sections will detail some of the design process, as well as some interesting observations I had when working on it. The preliminary version is complete, and you can try it here. This was when I decided to build a solver to handle some of these puzzles for me. As I sat there cutting up small Tetris pieces to figure out a particular torturous Tetris-fitting puzzle, I wonder if this process can be automated. A lot of these symbolic puzzles, ranging from simple path-finding to complex segmentation problems, can be solved with brute-force approaches. It’s a joy to figure out the rules of both, but after a while I found myself looking forward to environmental puzzles more than the symbolic ones. The former comes with symbols on the maze to satisfy (e.g., a black hexagon has to be traversed by the path), while the latter hides its rules and clues in the environment (e.g., the path is indicated by the reflection of sunshine). These rules can roughly be divided into 2 groups: symbolic and environmental. By drawing a path from start to finish, you complete the puzzle by satisfying specific rules. #The witness puzzle solutions tetris full#I bought it on day one, and it’s well worth it’s full price.Īll the puzzles in The Witness take the form of path-searching on a rectangular maze. On top of being a great puzzle/exploration hybrid, The Witness is able to teach its players without any word and exposition. You basically wander alone on a dreamy island and try to solve the puzzles littered around it’s like Professor Layton, but with all the NPCs turned into stones. In case you haven’t heard about it, The Witness is an excellent video game.
