Five victims of the billiards hall attack died of their wounds overnight, said Shakeel, who put the death toll at 86.
The strike was the worst of three deadly bombings targeting Shiites and soldiers in Quetta and worshippers at a Sunni mosque in the northwest on the same day.
It appeared to be Pakistan's worst day of violence since October 2007, when 150 were killed in a bombing aimed at Pakistani politician Benazir Bhutto. She survived the blast but was assassinated two months later.
Last year was the bloodiest year for Pakistan's Shiite community, with over 400 members of the sect killed in targeted attacks throughout the country, according to Human Rights Watch.
Violence has been especially intense in southwest Baluchistan province, where Quetta is the capital and the country's largest concentration of Shiites live. More than 120 Shiites were killed in targeted attacks in Baluchistan in 2012.
In Quetta on Friday, suspected militants fired rocket-propelled grenades at a terminal where trucks carrying supplies to NATO troops in neighboring Afghanistan were parked, said Shakeel, the senior police officer. The attack killed two people, wounded another and set 10 trucks ablaze.
