 The concept of the hockey pinball was to reunite two games that almost everyone knows of, and give it a new twist in its gameplay. We chose pinball and hockey table because the first game is usually played in solo while the other requires atleast two players. Their basic rules being quite different, we wanted to combine them to create a 'new type of game' that would still be relatively familiar and intuitive in its rules.

Because of the nature of the game, the marble seemed the most appropriate object to choose from the list.

The first sensor we had used, the LDT piezo sensor, had to be dropped because its capacities did not respond well with our game: the marble would have needed to hit hard on the sensor to trigger the next move, which could have potentially damaged said sensor.

We opted for a photocell sensor and a narrow angled light to trigger the game results. The outcome was just as efficient, but not damageable for neither the sensor nor the physical box.
