The reference point version has a different context. Based on the proportional reasoning skill level (measured before) the player has a specific job in the hotel (e.g., internship). The reference point is that the player is told that a promotion (e.g., bar tender) is possible, but that first some proportional reasoning tasks of a higher level must be performed. The reference point version is different from the original version in the introducing backstory, the removal of money rewards, the addition of a progress bar as an indication of how much tasks the player still has to do in order to get the promotion, replacement of the map with holiday destinations by a 'certificate wall'.

The progress bar is always visible (in the room, subgames etc.). When sufficient progression is made, the player receives a part certificate.
