My son (4 years) loves this puzzle about everything. We must help the keepers to capture the monkeys. And there really are many different variations, on the contrary to the puzzle of the castle, where you have to look for the princess. The monkeys are not always hidden in the same place, one has to ask visitors and help with different things. By the way you also get great information about the animals. Also the puzzle produces a top quality and definitely worth the money. My 4 year old son can already solve the tasks independently, but also my 7years son didnt enjoy it and play it often.
