The rules speak for themselves
8: the dots in the zone add up to 8. =: every cell of the zone has the same number of dots. ≠: every cell has a different number of dots. >3 and <3: every cell has more, or fewer, dots than the number. Even and Odd: every cell is even (0, 2, 4, 6) or odd (1, 3, 5). Crown: the crowned cell must be strictly the highest of its zone. A zone gets a check mark as soon as it is full and true. Every puzzle has exactly one solution, found by logic, never by luck.
