Core team: ~15
Time on project: ~19 months
Here are some Solitaire videos I recorded when we were brainstorming on Ad Creatives.
For such a seemingly simple and basic game, there were many assumptions I had coming into the project that were disproven by data. One was that Solitaire was such a universally recognized card game, that the rules needed no explanation. A few user reviews that complained of 'no moves' when the cards were dealt indicated that those Players weren't aware of drawing cards into the waste pile.
Other Players complained of playing hundreds of games without having won a single one. This may be an indication that those Players are clicking on the 'Replay Game' button instead of 'New Game', and playing the same deal over and over.
