IN 3D PUZZLE – Old House you have to put together a puzzle, finding yourself in three-dimensional space. The main character is tasked with creating a beautiful house, but this will require solving puzzles and interacting with numerous environmental objects. The gameplay is focused on getting to the necessary items hidden in different parts of the structure. This requires opening passages and obtaining clues or signs that help complete the quest.

The user will see the room and what parts it lacks. The missing objects are highlighted on the screen in green, which will help to understand what exactly needs to be found. The gamer needs to approach the object, take it with the left mouse button and take it to the place marked in green. If it is the right thing, it will end up at the designated point, and the player will receive points that will increase him in the leaderboard.

The faster the user collects items, the greater the chance of unlocking achievements and completing the mission. If the wrong item was brought, it will return to its starting point, causing the participant to lose a sufficient amount of time. As you progress, it is more difficult to find the necessary goals, since they are in hidden places. Each session, the location of things changes thanks to procedural generation.
