I rolled the red die 56 times.
the probability of getting +Card = 0.642857143 (36 times)
the probability of getting -Card = 0.160714286 (9 times)
the probability of getting -1 points = 0.196428571 (11 times)
The longest streak of +Cards was 8 in a row. I recommend rolling the red die every turn. Also, I got 3 hit once after 50 attempts
