All five classical games on Sunday finished drawn, which meant they all went down to Armageddon. Four out of five sudden death games favoured the player who had the black pieces.
In the classical game, Grischuk quickly gave up a pawn. A little later, Mamedyarov had to go for a repetition in order to prevent Grishuk's heavy pieces to infiltrate on the d-file. In the subsequent Armageddon match-up, we saw once again how the need to win led the white player to make decisions he otherwise might not have made:

In the classical game, Aronian launched a sacrificial kingside attack, which only gave him a draw by perpetual check. The Armageddon game lasted 97 moves. In the final position, Ding Liren had a queen against Aronian's rook and two pawns. The Armenian finally managed to secure the draw and thus was awarded the full point despite having a material disadvantage.

Maxime Vachier-Lagrave opened with 1.e4 in the classical game, whereupon Carlsen predictably chose the Sveshnikov variation of the Sicilian Defence. The Frenchman never got even a slight chance to fight for the win:
In Armageddon, Vachier-Lagrave opted for 1.c4 and the World Champion responded with 1...e5, a move that is currently hugely popular in the elite. Also in this game, Carlsen was completely in control at all times:

In the classical game, none of the players found a way to get winning chances, so they simply exchanged their pieces. Finally, not much happened and a draw was agreed.
The Armageddon game followed the same storyline. Making use of a strategy similar to the one employed by Magnus Carlsen, Anand secured the full point by drawing with the black pieces:

The Catalan was played in the classical game. With two well-placed knights against Caruana's rook, the Chinese player obtained an advantage early in the game. However, he could not make much of it and repeated the position before move thirty. Perhaps Yu Yangyi felt he had a better chance against Caruana in the blitz encounter — after all, the American has a reputation of not being so strong in this discipline. And, indeed, Yu Yangyi got the point in the Armageddon match-up, but only after a tough struggle...and quite a bit of luck:
