Here is a new game for science and engineering, to determine between two people:

Supply:

- Two pairs of scissors. If someone is left-handed, they should have left-handed scissors.
- A large sheet of paper with perfect 90° corners
- Some witnesses
- A planimeter or something like it

Instructions:

- Select by mutual agreement the distance in from the edge to cut. For an A4 or 8½ × 11, maybe 3 cm or 1 in.
- At the same time, start each person starts cutting a strip off their side of the paper by using the scissors.
- When complete, the witnesses use the planimeter to determine the variation from a true straight line of each of the two cuts. The person with the smallest total area above and below the perfect line wins.
- If both are identical, the person who did it using fewer cuts wins.
- If both are identical, the person who did it more quickly wins.

This is best done with waste or scrap paper that is blank on one side, to prevent paper waste.

As an advantage over the other paper based game, rock-paper-scissors, it is based on skill and not chance.
