My final idea

One day a group of boys were helping thier friend clean out his attic and they come across a peculiar looking gameboard called the weeji board. That night they all got toether and played it knowing that playing it would mean they would be in contact with the spiritual world. They began playing and nothing happens. They stop playing and started to misuse the game. Eventually they get bored and stop playing the game and then go downstairs and begin to watch a film. Suddenly the power goes out and all the windows slam open. They all jump and run into the kitchen. After they have all calmed down they go into the living room again but now all the electricity is out. They hear footsteps upstairs but everyone is scared to go so one boy finally steps up to go. He goes up with his walkie talkie and they try and communicate and at first they can until the group hear a loud scream and then the walkie talkie cuts and this is the beginning of everyone going missing one by one.
