1) Familiar names
As a nod to the host nation, the round robin groups have been christened red and white - the colors of the Singapore flag - as they were at the tournament's previous home, Istanbul.
2) New faces
Four of the qualifiers - Simona Halep, Eugenie Bouchard, Ana Ivanovic and Caroline Wozniacki - were not present at last year's WTA Finals. Halep and Bouchard are both making their debut.
3) Bucking the trend
Bouchard and Halep will hope to fare better than the most recent WTA Finals debutantes. In 2012, Sara Errani and Angelique Kerber won just won match between them.
4) Red hot favorite
Serena Williams is looking to win her third straight WTA Finals crown, and despite being placed in arguably the trickier of the two groups, she will fancy her chances. Her combined win-loss record against Halep, Bouchard and Ivanovic is 11-1.
5) Up against it
If past records are anything to go by, Ivanovic is up against it. She has won just two of 13 matches against her fellow Red Group members.
A crumb of comfort for the Serb comes in the shape of her late season form. Since the US Open, Ivanovic has won eight matches and one title (Tokyo). She has also won more matches (56) than any other player in the draw.
7) In the White Group
Equally impressive has been the recent performances of the White Group's top two seeds, Petra Kvitova and Maria Sharapova, who triumphed in Wuhan and Beijing, respectively.
8) Familiar foes
Sharapova saw off Kvitova in the Beijing final. This was their eighth career meeting, the last five of which have gone the Russian's way.
9) Radwanska's challenge
In six previous appearances at the WTA Finals, Agnieszka Radwanska has won just five matches. To make matters worse, her combined record against Sharapova, Kvitova and Wozniacki is 7-21.
10) Odd one out
Radwanska is also the only player in the White Group never to have reached the final of the season-ending showpiece.
