Sum 12
Read full descriptionHide full description
Train your brain while having fun with numbers! This engaging domino game helps improve mental math skills as you strategically match pairs that add up to 12. It’s a great way for kids to practice quick addition in a playful and interactive way. Perfect for players of all ages who enjoy logic and number challenges! The goal of the game is to clear all the dominoes from the playing area. To do this, find two face-up dominoes whose values add up to 12 and select them one after the other. If their sum equals 12, they will be removed, allowing you to flip over any previously blocked dominoes. Keep in mind that a game is not always solvable, so you’ll need a mix of strategy and a bit of luck!
