AUTUMN 2025

Disaster struck the dog world: the Golden Bones of Professions have vanished—magical artifacts that helped dogs remember what they do. Without the bones, the chef-dog is making slipper soup, the builder-dog is putting a kennel on a garage roof, and the astronaut has mistaken a rocket for a giant tin can.

The devious Fake Science Cat couldn’t stand the dogs’ success and hid the bones in the most unexpected places. Now you can reach them only through riddles, goofy trials, and true cleverness.

Setting off on the quest are: Tormund, the Brabançon architect; Nebula, the greyhound astronaut; and Bonya, the Pomeranian barista. They believe that, with the kids’ help, they’ll recover the bones and restore order to the professions.

Spaceport “Laika-1” 🚀
The dogs are preparing a rocket launch but mixed up spacesuits with grooming coveralls. One pup put a bowl on his head instead of a helmet, and another is “checking” the engine by sticking his tail in it. To claim the bone, solve the cat’s first riddle and send the “Bowlship” into orbit.
If October 1 was a Tuesday, what day of the week will October 21 be?
Clinic of Tailed Doctors
Fox cub Pif asked Dr. Lloyd how to lose extra kilos—and got a puzzle instead! Help solve it to free Lloyd from the nasty cat’s spell.
On Mondays and Thursdays, Little Fox Pif goes to the gym. After each workout, he eats 3 apples from a huge bag of apples. On all the other days of the week, he puts 1 apple into the bag. By how many apples will the number of apples in the bag change in two weeks? Enter only the number.
Bakery “Paw & Bun”
The puppy-chef bakes everything in the shape of bones, paws, and tails. To win back the golden bone, you’ll need to solve a riddle.
A roll with a bone flavor was cut into 5 pieces. A cat came, took 3 pieces, and cut each of them into 3 parts. How many pieces are there in total now? Enter only the number.
Architecture Bureau “Kennel & Partners”
The dog architects decided to build skyscrapers, but everything keeps turning out kennel-shaped. One project is "Kennel-Eiffel Tower," another is "Kennel on the Moon." To move on, help restore the blueprint and explain to the architects that not everything in the world has to look like a kennel.
Architect Torik drew 6 straight lines so that several squares appeared. Not all of them are the same size. The maximum number of squares you can get with 6 lines was achieved. How many squares does Torik have? Enter only the number.
Music Studio “Bark Major” 🎶
The dog musicians have lost the beat: the trumpet barks, the drum whimpers, and the guitar is sniffing the speakers. The last bone is with the basset conductor, who conducts with his tail. To get it back, you must perform the first dog symphony in history—without any "barks" or "growls."
With their drumsticks, the dog musicians laid out the equation 1 + 2 = 8 on the table (see picture). But it’s wrong! Move one stick to make the equation correct. What number do you get on the right? Enter this number as the answer.
YEAH! We did it, and Pythagorean Pants Math School is magically orderly again!
