.losing_time?(first_total, value1, value2, first_run = false) ⇒ Boolean

Wikipedia: A come-out roll of 2, 3 or 12 is called “craps” or “crapping out”, and anyone betting the Pass line loses. Wikipedia: If the shooter rolls any seven before repeating the point number (a “seven-out”), the Pass line loses.

.winning_time?(first_total, value1, value2, first_run = false) ⇒ Boolean

Wikipedia: A come-out roll of 7 or 11 is a “natural”, and the Pass line wins. Wikipedia: If the shooter “hits” the point value again (any value of the dice that sum to the point will do; the shooter doesn’t have to exactly repeat the value combination of the come-out roll) before rolling a seven, the Pass line wins

Returns:

  • (Boolean)
