This game is appropriate for Pre-Intermediate level learners and focuses on prepositions of place and furniture/house vocabulary. The aim of the game is to escape from the house where the player has been locked up by his/her family (Complete reasons are given in the note which is under the moose head which is mounted on the wall over the fireplace.) You have to figure out how to escape the house.
First you should watch the video walkthroughs yourself to know exactly how the game is played and where to look for the puzzle bits which you have to put together before you can escape. Watching the videos will also help you with knowing what input language to expect and how to help your learners if they get stuck.
Here are the videos (the walkthroughs are for the older version of the game but as the puzzle bits are in the same places, the walkthroughs are still valid):
Diana Nazaryan found a written walkthrough for the game. Thank you Diana! :)
It would be a lot more fun if the game can be played in the computer laboratory of the school. If there isn't one, then you will have to set the game as homework and then get the students tell everyone where they found the puzzle bits and where they got with the game. To do this, they will need to take notes on where exactly each bit was found to tell the class. By listening to each other's stories the learners can start sharing tips, e.g. there is another bit under the pillow, etc. Learners take notes and try to find all the puzzle bits at home again.
