Anyone who likes sudoku will undoubtedly also enjoy Number Sums!
Maikel Dijkhuizen
The app starts with an English explanation. There are different numbers on the side and top. On a playing field with numbers you have to make the correct sum so that you arrive exactly at the numbers outside the grid. You do this by circling the correct numbers. Some boxes are unnecessary, because you don’t need them to make a correct sum. You must clear these boxes.
Do you eventually get stuck? Understandable, because the number puzzles are quite challenging. First tap a box and then tap the light icon to show a hint. The first clue is immediately available, but after that the app requires you to watch a video commercial in advance. Afterwards you will receive an extra hint. The further you go, the more extensive the puzzles. If you make two mistakes, the puzzle starts again.
Number Sums contains various sound and vibration effects, but you can turn them off in the settings if desired. A downside is that this app shows many advertisements and commercial videos. Pay a one-time fee of 5.49 euros (Android) or 5.99 euros (iOS) to hide it.
