Decryptor device

A decryptor device configured for a user to answer a question, said question being a preset set of secret codes, said preset set of secret codes comprising a plurality of secret codes selected from a given set of codes, said given set of codes comprising a plurality of given codes that are different from each other, said decryptor device comprising:

• a housing;
• a power supply module;
• a main control module electrically connected with the power supply module;
• a code input module provided on the housing, the code input module being electrically connected to the power supply module and communicatively connected to the main control module, wherein the code input module is configured to at least input answers, and the answers being a set of solution codes, the number of solution codes included in the set of solution codes being the same as the number of the secret codes included in the preset set of secret codes, wherein the solution codes are selected from the given set of codes;
• a display module provided on the housing, the display module being electrically connected to the power supply module and communicatively connected to the main control module, wherein the display module includes at least one set of display units, and wherein the display module is configured to, when the code input module being operated to input the answer, operate in association with the code input module so that each set of the display units displays a corresponding set of solution codes.
