I personally played through 8 different child level sudoku-style apps. After looking through this one, I knew I didn’t have to go any further!
The graphic interface is a pleasant to see, drag and drop setup—perfect for kids. The music is charming, and there are multiple levels of increasing difficulty; starting with one blank space, then adding more blank spaces as you advance.
One of my favorite features is that once you select a level, you continue to play at that difficulty until you choose to go higher (or lower 😉).
Using pictures instead of numbers reminds me of an IQ test, which is wonderful.
Full disclosure: I haven’t payed for the ad-free version yet, but I absolutely will. The simple fact that this developer HAS a free-to-play version (a rarity these days) alongside the ad-free version is honorable enough to warrant a dollar from me for their honest troubles! You know how it is and you’ve seen other apps that simply DEMAND you pay a tribute just to see how the game works—with no refund if you’re unsatisfied.
Highly recommended by this father of a six and a four year old.
