Numdactle

The Numdactle app is designed to challenge your logical and strategic thinking with Numdactle puzzles. We provide a grid with a few numbers, and your task is to find the missing number we ask for.
Here are the rules: The sum of the numbers in each row, column, and diagonal must be identical. Each number in the grid can only appear once, and while they may not be in sequential order, they are all part of a sequence.
We believe Numdactle is an excellent workout for the brain and that it improves memory and cognitive abilities. Therefore, the Numdactle App not only provides entertainment, but it also contributes to mental fitness.
You don't need online access to play the Numdactle app on your device, but you will need Internet access to retrieve your printable Numdactle puzzles that you can give out to friends, students, and so on.
Unlike other puzzle or game apps out there, the Numdactle app does not have any advertising, subscription fees, in-app purchases, or tracking. In other words, you can play Numdactle every day with no surprises or extra costs.
