Save the Princess

Your child thinks that math is boring? We will change their mind! The future honor student must help the brave knight, who is saving the princess from a terrible troll! And as a reward, the winner will receive… a cartoon. What needs to be done: 1) Solve interesting logical puzzles, collecting key answers. 2) Substitute the collected keys into the final puzzle and find the code. 3) Scan the QR code and enter the resulting combination of numbers. If the child made no mistakes, they will see an animated story about how the knight meets the rescued princess.
