I am looking for an online counterpart of a physical activity to conduct in a workshop. The physical activity had the following characteristics which I would like to keep in the online activity.
Repeatable: performing the same steps yields the same outcome each time
Strategy: participants employ a certain strategy to solve a problem
Collaborative: participants team up and combine their strategies to yield a better strategy
Measurable: the goodness of the outcome can be quantified in more than one way
To better explain the above points, the details of the physical activity are as follows. Participants are given a "maker box" containing miscellaneous items: tape, glue, cardboard, rubber bands, scissors, cutters, paper, paper clips, sticks, ruler, pens, pencils, etc. Each participant has to improvise and put together a paper clip launcher that propels a paper clip like a projectile. Participants then pair up, explain their design to their partner, and collaboratively build a new launcher incorporating some ideas from each of the 2 designs. Each team can set its own goals for the goodness of its launcher in terms of the distance covered by the projectile, the height reached by the projectile, the number of projectiles, etc.
The closest online counterpart I can think of is a strategy game, or maybe a physics simulator. But I am having trouble finding anything specific.
Please suggest a game or an environment which meets the above criteria and is simple enough that people can quickly engage with it without training or special installation.
