Watching people use the prototype proved…

  1. This idea — using real-time multiplayer mini-games to facilitate technical acuity of practical web development skills — has merit
  2. Concepts like wheels and decks of cards are foreign but exciting. Short, just-in-time instructions are of utmost importance.
  3. Early adoption of a product like this will depend upon the system’s ability to match similarly-skilled players. Failing to do this will cause beginners to feel terribly unskilled compared to other players, resulting in mass avoidance.
  4. There is not explicit demand for this sort of product, but there is excitement after players are aware of its existence.

The first mini-game offered the most delightful moment for players

By the time they saw ‘You won together!’, most players audibly expressed delightful surprise and understanding of the game’s multiplayer design

Opinions confirming two key design choices

  1. Using a wheel to select a random mini-game
  2. Using collectable cards as a way to select a topic or language

Notable thoughts confirming an interesting idea

I think this is an awesome idea. I this is a fantastic learning tool for beginners.
