The rules are easy to comprehend. Face eight columns of figures with digits 0 – 9 written randomly in each. Remove pairs of neighboring digits which differ in one (e.g. 2 and 3, 8 and 7). The major of them makes the tens, the minor is taken as units. These two-digit numbers are summed up to an important year in the human history. When no possible variants are left on the field, you receive the Chance of Ages. It is a possibility to remove any pair of subsequent numbers on the field. It is given only once, so choose wisely.
