Along with my teammates, we developed the idea of a card game based on Russian Roulette, and we iterated the idea, by changing the rules, adding or substracting elements, until we found a ruleset that made the game fun, and easy to understand.
Also along with my teammates, I helped conduct many testing sessions, in which we would analyze how the players behaved and what strategies they tended to use. Afterwards, we would also interview them, looking for their overall impressions and suggestions on how to improve the game.
I wrote a rulebook that explained in a clear and concise way how to play the game. I also designed the graphic aspect of it, as it had to work as a piece of relevant information, but also as a part of the physical product of the game. The rule booklet comes in both Spanish and English.
