Igor Almeida Figueiredo was on born October 11, 1977 in Rio de Janeiro, Brazil.

Prior 2009, Igor had only played on 10-foot tables which is the norm in his home country.

In 2009 he entered the PIOS series and finished 12th on the season ranking list. He also played in the 2009 IBSF World Snooker Championship and reached the final on his first attempt. In the final he lost by 10-8 to the vastly experienced Alfie Burden. Those results impressed and WPBSA offered him a wild card for the 2010/11 season.

During his first season Igor got some good results especially in the PTC events. This allowed him to stay on tour during the 2011/12 season. However due to the lack of sponsorship Figueiredo only entered qualifying for one ranking event, the 2012 World Championship, where he won three matches, before losing 7–10 to Joe Jogia. Other than that, he played in the inaugural Brazil Masters and defeated world number 17 Jamie Cope in the first round 4–2, but then lost by the same scoreline to Graeme Dott in the quarter-finals

In 2013, Igor received the nomination from the Americas region, and returned to the main Tour. However the lack of sponsorship again forced him to sit out the whole season until the 2014 World Championship. Again he reached the last 64 round: he beat Adam Duffy 10–4, Gerard Greene by 10-8 but was beaten heavily by Martin Gould in the next round (10-1).  Other than that, he took part in the 2013 World Games, where he lost 3–2 to Dechawat Poomjaeng in the bronze medal match.

In the 2014/15 season Igor was finally able to get some sponsorship. That allowed him to play in more events. Again he had a solid run at the 2015 World Snooker Championship, beating Nigel Bond and Rod Lawler , to reach the last round of qualifiers where he lost by 10-4 to Robin Hull.

Again Igor Figueiredo was able to stay on the tour, as he was given an International Development Main (two years) Tour Card as the Brazilian National Champion and, again he had to sit out most of the season. He entered the 2016 World Championship but this time he was defeated 10-2 in the first qualifying round by Matthew Selt. The next season, 2016/17, was probably his best: at the Welsh Open he secured wins over Alfie Burden, Anthony McGill and Dominic Dale, before falling 4–1 to Stuart Carrington. He also reached the fourth round of the Gibraltar Open by eliminating Sydney Wilson, Fraser Patrick and Thor Chuan Leong and lost 4–2 to Nigel Bond. Despite this, he finished the season ranked 111th in the world and was relegated from the tour.

Since being relegated from the main professional tour, Figueiredo has returned to Brazil and competed in the World Seniors Tour, albeit only occasionally. He was runner-up in the UK Seniors Championship in 2018 and winner of the World Seniors Championship in 2024, meeting Ken Doherty in the final on both occasion.

Hi win at the 2024 World Seniors Snooker Championship means that he will get an invitation to the 2024 Champion of Champions.
