Each of these puzzles are standard Nikoli puzzles, rethemed to include bulls in some manner. Solve the puzzles and then determine the prompted numbers.
Bull-Akari
A = The number of bulls that are not orthogonally adjacent to a numbered square = 6
B = The number of bulls on the perimeter (outermost rows and columns) of the grid = 5
Bull-Masyu
C = The number of times the loop intersects 4 or more consecutive white bulls = 5
D = The number of times the loop intersects 2 or more consecutive black bulls = 7
Bull-Numberlink
E = The number of cells connecting the yellow bulls (including the cells with the bulls) = 26
F = The number of cells connecting the violet bulls (including the cells with the bulls) = 20
Bull-Yajilin
G = The number of bulls inside the fence = 13
H = The number of bulls outside the fence = 18
Bull-Answer
- (A - C) + (E - G) + 5 = 19
- (A - C) + (F - H) + 17 = 20
- (A - D) + (E - H) - 6 = 1
- (A - D) + (F - G) + 7 = 13
- (B - C) + (E - G) + 3 = 16
- (B - C) + (F - H) + 3 = 5
- (B - D) + (E - H) - 2 = 4
- (B - D) + (F - G) + 0 = 5
Reading the numbers (A=1, B=2, etc.) gives the answer STAMPEDE.
