100 Doors Challenge is a click-tap escape room puzzle game. The player's goal is to open 100 doors to use an elevator to move to each new floor of a building. Their guide, Jonathan, walks them through every aspect of the game. Although the game refers to 100 doors, it actually consists of hundreds of levels across five modes (Basic Levels, Classic Pack, Christmas Pack, Halloween Pack and Holidays).
Each room has one or more doors for the player to unlock. In a room, they need to solve a puzzle or puzzles to find and use a key, tool or device to open the door to the elevator. For example, they might need to move a rug across a floor in a specific direction. Once they select the necessary item, the game automatically moves it to the player's inventory in the empty space below the room. They must then access the inventory to retrieve and use the key.
100 Doors Challenge also offers the player two paid tools to help them progress through the levels. They access these items using the icon marked with a question mark at the lower-right corner. They can buy a hint to help them find a needed object for 30 coins. They can also skip an entire level for 100 coins.
If the player wants to restart the game, return to the main menu, or adjust the sound, they use the icon at the lower-right corner.
