This toy is very unchallenging. My dog mastered both of these games after one go, and (much as I love him) he is no genius.
The 'cup/sachet' game is a joke.
I thought the cups would be tight fitting so he actually has to pull them out, however, when he sniffs at them the cups just fall over revealing the treat. It took his a couple of seconds to knock them all over and get the treats.
The 'slider' game however, is not quite as bad as he actually has to do something to get the treats.
It is very expensive for what it is and I would not recommend this item to anyone.
Unfortunately it has put me off buying other doggy mind games as they might be just as bad!
