Description
3-Sum is a math numerical placement puzzle, conceptualized and designed by a daughter to keep her elderly mom's brain sharp.
Young or old, if you can add three numbers then you can play this game. But, don't let the simplicity of the math fool you! While some puzzles are easy, others will definitely provide your brain a fun challenge.
There are four levels of math puzzle difficulty: Novice, Advanced, Expert and Master.
The object of the game is to fill a 3 × 3 grid with digits from 1 to 9 such that:
- adding the three digits in each row will equal the provided sum for that row;
- adding the three digits in each column will equal the provided sum for that column;
- adding the three digits on the diagonal starting from the top left cell and ending with the bottom right cell will equal the provided sum for that diagonal.
The puzzles can be completed by one person, or can be used by multiple players - family and friends - for hours of recreational and educational fun.
