Smart Park Darts Club hosted the tournament which is annually organised by the Dar es Salaam Darts Association (Dada) with a view to realizing successful promotion of the sport in the city.
The club registered maximum points in the team event of the competition to beat the rest of the competitors.
Lugalo Darts Club, which has of late become Friends' fierce rival, finished runners-up and Police Barracks Club were third-placed.
The tournament's men's singles and doubles events saw Friends maintain its supremacy, as the outfit's player, Noah Isaya, emerged champion in the men's singles event folowing a victory over teammate, Rashid Hussein, in the final.
The duo, then, teamed up to overcome Lugalo's Erry Botes and Pastory Masanja 4-2 in an entertaining final of the men's doubles event to lay their hands on the top honour.
Isaya expressed his delight at excelling in singles and doubles events, saying he fought gallantly right from the start. He said he will continue doing his best in the next events.
Masanja conceded good finishing by their opponents in the men's doubles final proved decisive.
"The game was tight, we all played well. Good finishing proved to be crucial for opponents' win...they were great on the aspect and that is why they emerged victorious," he said.
Friends' success in the regional club championship helped the outfit make up for its failure to win the Ram Ram Bharat Memorial Trophy Challenge held at the Patel Samaj Club in Dar es Salaam recently.
The women's singles event of the regional club championship was won by Lugalo's Beatrice Petro, who edged Police Barracks' Elizabeth Musa in the best of seven legs' final.
Subira Waziri and Maila Kale of Ibukoni Darts Club then halted Musa from realising complete sweep of honours when the former won the women's doubles event with victory over the latter and her team mate, Anna Saidia, in the final.
Tanzania Darts Association (TADA) chairman, Weston Asisya, attended the event and presided over the presentation ceremony.
Asisya congratulated Dada for stepping up efforts to promote the sport in the city and also praised the tournament's hosts for joining forces with Dada to develop the game.
He, as well, showered praises on Isaya and Hussein for excelling in this year's Kenya Open international championship.
He said the duo's success in the event has substantiated Friends Darts Club's prowess in the sport.
Asisya handed Isaya and Hussein cash prize, as well as a certficate of appreciation for the latter's outfit.
He requested Friends Darets Club to continue training intensively with a view to maintaining its impressive showing in major competitions in the East African region.
Dada secretary general, Kamdasi Kibago, said the association needs financial support to organise competitions in the city on regular basis.
Friends received 300,000/- and a trophy for winning the regional club championship, runners-up Lugalo took 150,000/- and third-placed Police Barracks Club were presented with 75,000/-.
Dada also used the event as an opportunity to welcome the hosts, who are the association's newest member, to the regional darts fraternity.
