Mysterious elevator

Mysterious Elevator places you inside a skyscraper with 100 floors, where a sarcastic Keeper of Numbers presents mathematical and logical tests. Progress depends on solving challenges while the old elevator carries you through the building.

The puzzles include arranging number and sign blocks into equations, along with additional logic problems. Some tasks use straightforward arithmetic, while others conceal a trick, so reading the available pieces closely matters. The elevator setting gives every answer a sense of consequence, with a wrong solution threatening to make the elevator crash.
