Digikoo is a game for all those who love numbers and Sudoku. It's a great way to keep your mind sharp. The rule is simple: only put the same number once in each row and column. The grids range from 2 combinations (it's a gift) to 9, where the headache becomes real. Can you reach level 42?

Verdict
The clearest difference is price: NinjaSudoku at Free against Digikoo's $1.99. Digikoo's advantage is update cadence (every 6 months vs every 52 months) and iOS requirement (11.0 vs 15.6). On ads, in-app purchases and device support there is nothing between them.
