We're finally starting to see a few developers put some real muscle behind software geared for children, and Avokiddo is in that rare company. Their Thinkrolls series has been premium quality from the start with Kings & Queens gently expanding on that pristine groundwork.

Essential. Unmissable.

Fun for all ages

We bought Thinkrolls and Thinkrolls 2 for the iPads at our library. I loved playing the games so much that I bought them for myself. Out of the three Thinkrolls games, this one is by far my favorite. The graphics are gorgeous. I love that you get to customize the characters rather than choosing a pre-made character. The only problem is that when using these apps on my iPhone 8 Plus, many of the characters and objects are located too close to the edge of the screen and when I swipe to move them the iPhone menu comes down and pauses the game. Perhaps if they were a little farther away, it would stop that from happening. Other than that, I love playing these while waiting in line or laying in bed.

A fabulous game!!

I got this for my granddaughter a few years ago. She’s 8 now. She loves the challenge of this game! It really helps a child -or adult for that matter- visualize and think ahead. (She’s definitely quicker at it than I am.). She loved the their Think Rolls games too!
