The men were sentenced by Uddevalla District Court to six months and eight months in jail respectively.
Of the four remaining men charged in the case, two were fined the equivalent of 80 days' wages and two were cleared of the charges of illegal gambling.
The man sentenced to eight months in prison was also convicted of driving under the influence. The man's lawyer, Henrik Olsson Lilja, said his client intended appealing the decision.
"We think the district court has gone too far with a prison sentence. A reasonable consequence might have been a suspended sentence coupled with community service," he said.
The illegal poker tournament was broken up by police in March 2007.
Each of the participants paid €250 ($390) to join the tournament. The organizers pocketed €30, while the rest of the money went into the prize pot.
Prosecutors said that the competition was arranged in conjunction with a gaming company, and took place in a conference centre in the town of Grebbestad.
The maximum prize money at the event was €50,000. Two of those charged worked for the gaming company; another two were locally-based organizers.
The remaining two people were charged for renting out the room at the conference centre.
