Dice towers

Dice towers are practical tools for dice games, designed to prevent the Dice from falling off the table or being manipulated. You throw the Dice simply into the tower and they fall through various levels before finally coming out the bottom and showing the result.

Did you know that dice towers have been around since the fourth century AD? The Rhineland State Museum in Bonn, Germany has what is probably the first ancient dice tower on display there. More information in English:https://en.wikipedia.org/wiki/Vettweiss-Froitzheim_Dice_Tower
