Jersey won both of their ICC Europe Division One T20 matches on the first day of the international tournament.
They beat Norway by 108 runs, with man of the match - teenager Jonty Jenner - scored 81 in a total of 236-5.
Later on Saturday, Jersey beat pre-tournament favourites Italy by four wickets for their second victory.
Jersey were set a target of 156 to win and, with 26 runs needed from the last two overs, Corey Bisson and Ben Stevens saw them home.
Jersey and Guernsey are the only unbeaten teams remaining with three matches to play.
The six teams are back in action on Monday.
