Number Sums
Number Sums
Number Sums focuses on the intricate mechanic of balancing sums across rows, columns, and distinct colored regions. Unlike standard math puzzles that only look at linear totals, this game introduces a third layer of complexity with these regions. Each region is a cluster of cells that must add up to a specific value shown inside it. This means every number you choose must satisfy three different criteria simultaneously: the row total, the column total, and the regional total. This interlocking system creates a deep logic challenge that requires careful mental arithmetic and strategic planning.
The game is designed as a comprehensive brain-training tool. You are presented with a grid filled with numbers, and your goal is to circle the ones that belong to the solution while effectively erasing the ones that do not. Because each level has only one unique solution, the gameplay is a process of deduction. You might find that a number works perfectly for a row and a column, but it pushes the regional sum over the limit. This forces you to reconsider your entire approach to that section of the board, making the experience both challenging and rewarding for those who enjoy math riddles.
As you progress, the puzzles vary in difficulty, offering a range of complexity to suit different skill levels. The inclusion of audio elements provides a layer of sensory engagement as you interact with the numbers. The interface is practical and straightforward, allowing the focus to remain on the logic puzzles. Whether you are looking to sharpen your everyday mental math skills or simply enjoy a quiet session of brain training, the game provides a structured environment for logical growth. Each puzzle is a self-contained exercise in arithmetic, designed to be solved through patience and careful calculation. The single-player nature of the game ensures you can take as much time as you need to find the single correct path to the solution.

How to Play
Your objective is to identify the correct numbers in a grid that satisfy three different sum requirements. Look at the numbers on the sides of the rows and columns; these are your primary targets. Additionally, look at the numbers inside the colored regions. You must circle the numbers that, when added together, equal all of these clues simultaneously.
Start by examining the smallest regions or the rows with the smallest target sums. If a target is 3 and the row contains a 5, you know the 5 must be erased. As you circle correct numbers and eliminate incorrect ones, the remaining possibilities will become clearer. Remember that every level has exactly one solution.
If you find a conflict where a number fits the row but breaks the regional sum, you must backtrack and try a different combination. The game is won when every row, column, and colored region matches its designated total. Take your time to calculate each move carefully to find the single path to victory.

Tips & Tricks
- Focus on the colored regions first to narrow down number possibilities.
- Use the process of elimination to remove numbers that are too large for a target.
- Double-check that a selected number satisfies the row, column, and region.
- Look for regions with only one or two cells for the easiest starting points.
