Icosoku is a puzzle designed to make simple addition a challenge. Users explore every angle of this puzzle as they make all of the dots touching a yellow peg add up to that number. The puzzle can be solved regardless of how the yellow pegs are arranged, so there are thousands of games to play. It offers "the ability to play a new puzzle every time the number pegs are rearranged," Brandi Field, general manager of Recent Toys, told TDmonthly.
—  Two of 12 retailers named games from Recent Toys among their favorite products at ASTRA 2010, during a June 2010 TDmonthly survey.
