Creeps' Castle

This is a children game from Spear's. It does not use a battery , but a ball bearing to get the doors and traps moving. The horror theme is always attractive to kids.
Each player tries to go from the bottom to top of the 3D castle. Each time a piece lands in a white square, the player must press hard on it in order to release the ball. The ball will fall down and on its way through certain doors and traps will "flick" hitting the players pieces. Those hit pieces will fall from the Castle and need to start again !!
Look the pictures and rules, and you can figure it out quickly.

The "magic" part, is that the ball, can follow 3 different ways of coming down... so flicking different traps and doors each time accordingly. Therefore, some shouting and excitement, and if lucky relief, when standing in a dangerous place and you hear the ball coming down...it could be you!
