What is the concept of a fully mechanical secret room?

It is completely mechanical. From a publicity point of view, it is a gimmick to promote the secret room. In fact, it has little to do with machinery. It is a simple microcontroller controlled prop. It’s all mechanical, so in terms of the type of secret room game, the division isn’t very accurate. From the perspective of player behavior, the types of secret room games can be divided into decryption type and operation type. One requires more brain use, and the other requires more hands-on experience. According to the principle of the mechanism, it can be divided into ordinary mechanisms and mechanisms with electric control (so-called machinery). Due to the electric control, more operations are possible for the player, for example, the player can unlock it by tapping. Therefore, chambers with "mechanical" mechanisms tend to be more operational chambers. However, traditional non-"mechanical" prop mechanisms only use password locks due to insufficient openness, so they can only design more decryption links. However, it is not that non-"mechanical" mechanisms can only realize the decryption process. For example, using a magnet to suck out the key from a tube. This mechanism does not have a "mechanical" component, but it is a typical operation and gameplay mechanism. Therefore, if "all mechanical" is used to summarize a type of secret room, then its meaning is that the mechanisms in the secret room are all electrically controlled mechanisms. The opposite is semi-mechanical, not entirely. There are zero machines and no electric control mechanism at all. However, this classification can only reflect the type of mechanism, not the type of game. Nowadays, there are many small mechanical equipment for secret rooms selling. You can go to Taobao and search for "secret room machinery" and spend a few hundred yuan to buy a few ready-made sets to achieve good results. Or you can buy it and research it yourself and imitate it~ I can’t bear to complain. There is a half-cent relationship between mechanical equipment and decoration.
