Cyclic method:

In cyclic method, If the number of teams is in even number, the team number 1 is fixed on the top of right-hand side and then other team numbers in ascending order consecutively downward and then upward on the left-hand side and then from the next round teams will rotate in clockwise direction. If the number of teams is odd then the bye is fixed on the top of right hand side and rest of the procedure will remain same. If the number of team is even number than number of rounds will be (N-1). If the number of teams is odd number then number of rounds will be equal to number of teams.

Fixture- No of matches=n(n-1)/2 = 8(8-1)/2 =28

No. of rounds=N-1= 8-1=7

Fixture- Cyclic method

1st round	2nd round	3rd round	4th round	5th round	6th round	7th round
A-B	A-H	A-G	A-F	A-E	A-D	A-C
H-C	G-B	F-H	E-G	D-F	C-E	B-D
G-D	F-C	E-B	D-H	C-G	B-F	H-E
F-E	E-D	D-C	C-B	B-H	H-G	G-F

(b) Cyclic Method : In cyclic method, if the number of teams is even, the team number 1 is fixed on the top of right-hand side and other teams in ascending order consecutively downward and then upward on the left side and rotate them clockwise. If the number of teams is odd, then bye is fixed on top right side and the rest procedure remains same. The number of rounds in case of even number of teams will be n -1, where n = number of teams. The number of rounds in case of odd number of teams will be n, where n = number of teams.

Example 1. Draw a fixture of 6 teams on league basis according to cyclic method.

Solution: Total number of teams = 6

Total number of matches

Number of rounds = n-1 = 6-1 = 5 rounds.
