Improve task game instructions
- Do not hide but explain the physics behind the game!
- Explain the card design, so that it becomes clear how to distinguish the cards representing up and down quark, which are depicted by an equilateral triangle pointing upwards and downwards, respectively
- Define the end of the game, when playing with task cards, e.g. a point limit
- Decide if and how it should be possible to change the task without fulfilling it
- Include instructions on how to add or remove impossible tasks and how to deal with them
- Add cards with extra functions e.g. joker, best candidates are bottom and top quark cards
