SumAQuad: Rules and How to Play
SumAQuad is a mathematical logic game that challenges your deduction skills. The goal is to complete both the corner circles and the main squares.
1
Each center cell (square) must be the exact SUM of its four surrounding corner circles.
2
Each row and column of circles must contain UNIQUE numbers from 0 up to the grid size (e.g., in 5x5, 0 to 5).
3
The board is complete when all circles and all squares have their correct values.
4
The puzzle can be solved using pure logic, no guessing required.
5
Right-click any cell to mark it as 'Safe' (✓) or 'Doubt' (?) if you need visual aids.
"The solution is unique. Every board can be solved using pure logic."
