Figure skating - Individual
Yuzuru Hanyu became the first Japanese man to win an Olympic figure skating gold as the teenager also claimed Japan's first title of the 2014 Winter Games.
The 19-year-old from Sendai fell twice but took his first major title ahead of three-time world champion Patrick Chan after the men's free skating final.
Denis Ten moved up from ninth after the short programme to take a first Olympic figure skating bronze for Kazakhstan.
After setting a world record score in the short programme, Hanyu sealed his historic victory with his free skate to Nino Rota's "Romeo and Juliet" in front of a capacity crowd at the Iceberg Skating Palace.
Carrying a 3.93-point lead in from the short programme Hanyu scored 178.64 for the free skate, despite a two-point deduction, for an overall total of 280.09.
Chan, 23, achieved 178.10 for his error-strewn performance to Vivaldi's "Four Seasons" and "Concerto Grosso" for an overall total of 275.62.
Alpine skiing - men's super-combined
Switzerland's Sandro Viletta won the men's Olympic super-combined topping a shock podium that included neither favourites Ted Ligety of the US nor Frenchman Alexis Pinturault.
The 28-year-old, who had only one World Cup win and podium so far, won with a combined time of 2min 45.20sec, after one downhill and one slalom run.
Croatian veteran Ivica Kostelic was second at 0.34sec, bagging his fourth Olympic silver and third in the combined.
He preceded Italy's Christof Innerhofer at 0.47sec, who takes his second medal at these Winter Games after downhill silver on Sunday.
The result turned all predictions upside down as combined world champion Ligety and young gun Pinturault failed to even make the top 10 in the Valentine's Day race.
Nordic skiing - 15km
Switzerland's Dario Cologna won his second gold of the Sochi Games and underlined his supremacy in cross country skiing with a dominant performance in the men's 15km classic.
Cologna finished in 38min 29.7sec, a colossal 28.5sec ahead of his nearest challenger Johan Olsson of Sweden who took silver. Daniel Richardsson, also of Sweden, won the bronze in 39min 8.5sec.
Cologna's gold is his second in Sochi after his win in the skiathlon that mixes both the classic and freestyle.
It is is third Olympic gold after he also won the 15km in Vancouver 2010 which was run as a freestyle event.
Biathlon - 15km
Belarus' Darya Domracheva put in a phenomenal skiing performance to win her second biathlon gold of the Sochi Olympics in the women's 15 km individual.
Domracheva, who already clinched the pursuit gold this week, was penalised for one missed target in her first standing shoot but was simply too fast on skis for her opponents to get near.
The Belarussian, 27, known as "Dasha" to her friends, finished in 43min 19.6sec, 1min 15.7sec ahead of her nearest rival Selina Gasparin of Switzerland who took a surprise silver and shot clear.
Fellow Belarussian Nadezhda Skardino, who was born in Russia but switched allegiance to Belarus, took bronze in 44min 57.8sec.
Skeleton - Singles
Lizzy Yarnold of Great Britain earned her country's first gold medal of the Sochi Olympics with victory in the skeleton.
The 25-year-old, who led the event after the two opening runs, produced two more consistent rounds to clock a combined time of 3min 52.89sec to finish 0.97sec ahead of second-placed Noelle Pikus-Pace of the United States.
In her third heat, Yarnold, who repeated the triumph at the 2010 Vancouver Games of compatriot Amy Williams, set a new track record with a time of 57.91sec.
Russia's 2013 European champion Elena Nikitina was third with a time of 3:54.30.
Freestyle - Aerials
Alla Tsuper shocked a top draw field to win the women's aerials in her fifth Games.
The Belarussian had never before won a medal in four previous attempts and was ranked only 13th in the World Cup standings coming into the Olympics.
Yet the 34-year-old was the only athlete to land perfectly in the final four shoot out and she edged out world champion Xu Mengtao of China into silver with Australia's reigning Olympic champion Lydia Lassila taking bronze.
Tsuper's gold medal ensured this would be the most successful Winter Games in Belarus's history.
