Elephant's foot umbrella stand

A parlour game, played by a number of players, preferably only one of whom should be familiar with the game.

Play takes the form of rotating around the group of players, each player adding an item to a list which is either allowed or disallowed. The basis of the game is not only to remember the list, although this can be difficult as the game progresses, but also to work out the logic behind what items are allowed.

The game usually takes the following format:

Player 1: "I went to the shop and I bought an elephant's foot umbrella stand".

Player 2: "I went to the shop and I bought an elephant's foot umbrella stand and a large orange plate".

Player 1, or the player who knows the rules, would then allow or refuse The New item.

Play then continues in this manner until everybody has worked out the logic.

Solution

The logic behind the game is that each new item must begin with the next letter of the phrase 'elephant's foot umbrella stand'.
