Chain Sums is an exciting and challenging mathematical game that puts your number-crunching skills to the test. The game starts with a creative twist – you must assemble sums using chains that connect the points of a wheel. With the help of your mouse or keyboard, you will link the points to create mathematical equations and score points based on how quickly and accurately you solve the puzzles. The game progresses as you solve increasingly difficult problems, and you can even challenge your friends to beat your score if you’re feeling competitive.
