I've been thinking about this for a long time and am not sure if this game could be done on vuforia mainly because I don't know how to make an image target a collider. Just watch the first few seconds of the game and you'll understand it. I'm fine with keeping the marker on the table, not sure how they did it without it.
Is this AR game possible on Vuforia
My guess is that they are using the initial target as starting point and storing the pose of it in order to remove the initial target. You can use the positional device tracker in Vuforia to accomplish something similar. Take the pose of the Image Target and use that position to hit test against the PDT to keep the object in place there.
Alternatively you could leave the initial target there to ensure stability and start using other targets on top of the initial target.
