The tournament is played in Rounds. In each round, play is by Group,
with each player playing against everyone else in the group.
In a Freestyle (or FS, for short) game, the following rule applies at the start of the game:
One player, designated A, names the first blue piece and first red piece to be played.
The other player then has the option of which colors to play: blue/red
(starting with those pieces) or yellow/green without any other restriction.
Play then proceeds according to normal game rules.
The designated pieces for blue and red can be placed in any orientation
of the blue/red player's choosing.
Matches are one game - no rematch. (In the last two rounds, tie games are replayed.)
In Round 1:
Players in each group group are seeded by their Ranking Points, 1 - N,
with 1 being the highest seed.
If the sum of the two seeds is even the higher seeded player is A,
and if the sum is odd, the lower seeded player is A.
For a seven player group it works out this way:
Seed |
A vs |
B vs |
1 |
3,5,7 |
2,4,6 |
2 |
1,4,6 |
3,5,7 |
3 |
2,5,7 |
1,4,6 |
4 |
1,3,6 |
2,5,7 |
5 |
2,4,7 |
1,3,6 |
6 |
1,3,5 |
2,4,7 |
7 |
2,4,6 |
1,3,5 |
After the first round:
players are seeded in groups as described in the next section;
the higher seeded player has the
choice of being A or B (choosing pieces or colors respectively).
Players are seeded by their Pentolla Rating Points at a specified time.
They are listed in descending order of points, then assigned to groups as shown in the table below.
Blue |
1, 8, 9, 16, 17, 24, 25 |
Yellow |
2, 7, 10, 15, 18, 23, 26 |
Red |
3, 6, 11, 14, 19, 22, 27 |
Green |
4, 5, 12, 13, 20, 21, 28 |
After Round 1, Pentolla ranking points are not used to rank or seed players.
The top 4 of each Round 1 group of 7 will advance to Round 2.
The rankings are determined as follows, with the steps applied until each player has a unique ranking:
In case of three or more tied players, the process is iterative:
The ranks from Round 1 are used to determine the makeup and seeding of the Round 2 groups.
Each Round 2 group has a #1, #2, #3, #4 from different Round 1 Groups, seeded in that order.
Six different combinations of four groups are specified and a random process determines which of those will be used.
The possible groupings are:
1: (B1,Y2,R3,G4) . (B2,Y3,R4,G1) . (B3,Y4,R1,G2) . (B4,Y1,R2,G3)
2: (B1,Y2,R4,G3) . (B2,Y4,R3,G1) . (B3,Y1,R2,G4) . (B4,Y3,R1,G2)
3: (B1,Y3,R2,G4) . (B2,Y4,R1,G3) . (B3,Y1,R4,G2) . (B4,Y2,R3,G1)
4: (B1,Y3,R4,G2) . (B2,Y1,R3,G4) . (B3,Y4,R2,G1) . (B4,Y2,R1,G3)
5: (B1,Y4,R2,G3) . (B2,Y3,R1,G4) . (B3,Y2,R4,G1) . (B4,Y1,R3,G2)
6: (B1,Y4,R3,G2) . (B2,Y1,R4,G3) . (B3,Y2,R1,G4) . (B4,Y3,R2,G1)
The top two players from each Round 2 group of 4 will advance to Round 3.
Round 3 groups are made up of two #1's and two #2's, all from different Round 2 Groups.
Three possible combinations of two groups are specified, and a random process determines which of those will be used.
Using T, E, B, S to designate the Round 2 groups, the Round 3 groups are determined
by the placement of two of the number ones, with the rest falling into place:
1: (T1, E1, B2, S2) . & . (B1, S1, T2, E2)
2: (T1, B1, E2, S2) . & . (E1, S1, T2, B2)
3: (T1, S1, B2, E2) . & . (B1, E1, T2, S2)
No matches are repeated from Round 2 to Round 3, but are possible from Round 1 to Round 3.
Within a group, the seeding of the #1's vis-a-vis each other (and similarly for the #2's) is:
The top two players from each Round 3 group advance to the semi-final round.
Each semi-final has a #1 from one group and the #2 from the other group. The #1's have the higher seed in the semi-finals.
If a semi-final or final game is a tie game, it is replayed, with the players switching A and B roles.
The winners of the two semi-finals play.
The #1 seed is given to the player who:
The losing players in the Semi-Finals play off for 3rd/4th place, seeded similarly.
If a player withdraws from the tournament after it has begun, what happens depends when it occurs.
If a round is in-progress, his games (even if he played all of them) do not count and the remaining players continue without him.
If it is between rounds, then he is removed from the next round, and everyone who finished below him in the previous round moves up one place.
After Round 1 or Round 2 completes - sometimes immediately, sometimes by pre-announcement,
one of the tournament organizers uses
the Pentolla /random function which produces
a random digit (0 - 9).
For Round 2, the function is used repeatedly until a number in the range 1-6 comes up, and then that is used.
For Round 3, it works like this:
1, 4, 7: use grouping #1.
2, 5, 8: use grouping #2.
3, 6, 9: use grouping #3.
0: try again.
For seeding within Round 3, if it comes down to random chance,
the /random function is used, with one of the players calling
odd or even. If the call matches the result, that player is seeded higher.
Notes:
(1): In case groups are not of equal sizes, normalized win-loss percentages, or per-game points differences are used in lieu of totals.
