declare a winner.

3.  Best Use:
• When the number of entries is large.
• When the time is short.
• When the number of playing venue is
limited.

4. Formula:
where: G --number of games
N --number of entries
G= N-1

5. Formula:
Where:
P --least power of 2 higher than N
Fixed value—2, 4, 8, 16, 32… (2x2=4x2=8x2=16x2=32…)
N--number of entries
Bye --entitles a team to advance to the next round without
playing
-- able to play during second round

6. There are 6 participating teams in
table tennis.

14. DOUBLE-ELIMINATION
TOURNAMENT

15. DOUBLE-ELIMINATION TOURNAMENT
 a type of elimination tournament competition in
which a participant ceases to be eligible to win the
tournament’s championship upon having lost two
games or matches.
It stands in contrast to a single-elimination
tournament, in which only one defeat results in
elimination.

16. Purpose: All contestants remain in
championship contention until they lose two
games
Advantages:
•A player or team must be beaten twice to be
eliminated
•It selects a more adequate winner
•It maintains player motivation right up until
the end
Disadvantages
•It takes longer to run
•It emphasizes elimination

17. Instructions
•Formula – min # of games: (N-1) 2
Max # of games: 2(N-1) + 1
•Construct a single elimination tournament with
appropriate # of slots
•Close the blocks of first round
•Complete the “losers side”
Note – every odd # round should have the same
# of slots as the previous round
•Criss cross losers so they don’t play the same
team again.

18. • One method of arranging a double-
elimination tournament is to break the
competitors into two sets of brackets,
the Winners Bracket and Losers Bracket
