North Country Showcase, the new store in the St. Lawrence Centre Mall in Massena, will host a “Sum of Which” tournament on Saturday, September 23rd at 11am. “Sum of Which” (patent pending), is a unique scrabble-style board game with numbers that was created by SUNY Potsdam Math Professor, Becky Duprey. “Sum of Which”, is a multi-generational game of numbers and strategy that has now been played by children and adults in nine countries. It is a stimulating game that requires players to make sums of ten to earn points. If you can add to ten, you can play the game and if you enjoy strategy, you will love the game!. The tournament is free to enter and space is limited, so form a team of 2 - 4 players ages 12 and up, and sign up soon in the store or by calling 315-705-2170. Prizes of $50, $25, and $10 gift certificates will be given to the top three teams. Becky will be on hand at 11am on September 23rd to lead teams in a warm-up game to prepare for the competition. Games are also for sale in the store. North Country Showcase is located at St. Lawrence Centre Mall, Route 37, Massena, New York.
