Spooky Doo is the latest addition to Zoch’s brain twister family of games. It comes in a beautiful metal box and features two new items, the barrel and the fez. While the basic Geistesblitz rules still apply, the fez can be placed over any of the other items. It is a new challenge to know which item is hidden underneath the fez at all times.

Balduin, the house ghost, found an old camera in the castle cellar. Immediately he photographed everything that he loves to make disappear when he is haunting  – including himself, of course. Unfortunately, the enchanted camera takes many photos in the wrong colors. Sometimes the green bottle is white, at other times it's blue. Looking at the photos, Balduin doesn't really remember any more what he wanted to make disappear next. Can you help him with his haunting and quickly name the right item, or even make it disappear by yourself? If you grab the right items quickly, you have a good chance of winning...

The lightning fast shape and color recognition game that is sure to test the reflexes of kids, families and gamers alike. In Duuuszki: Edycja limitowana, five items sit on the table waiting to be caught. Each card in the deck shows pictures of two objects, with one or both objects colored the wrong way. With all players playing at the same time, someone reveals a card, then players grab for the "right" object – but which object is right?

If one object is colored correctly – say, a green bottle and a red mouse – then players need to grab that correctly colored object.
If both objects are colored incorrectly – say, a green ghost and a red mouse – then you look for the object and color not represented among the four details shown. In this case you see green, red, ghost and mouse, so players need to grab the blue barrel.
The first player to grab the correct object keeps the card, then reveals the next card from the deck. If a player grabs the wrong object, she must discard one card previously collected. Once the card deck runs out, the game ends and whoever has collected the most cards wins!

The new key feature is now the fez. Fez is used to cover one of the other elements. When the players are obliged the catch the fez they instead say the name of an item under the fez. When the players are obliged the catch the item under the fez, they instead catch the fez to show the item that was covered. Whenever fez is caught the player holding it may cover the same or new item.
