There is a similar game called "Kim´s game". Rudyard Kipling makes mention of it in the novel Kim.
Let´s say that you put twenty objects on a table. They could include a match, pen, knife, card, safety pin, ticket, coin, stamp, etc. You cover them with a cloth. The player is brought to the table, the items are uncovered, and the player has a limited time (one minute?) to memorize what is on the table. The items are covered again, and the player writes a list of all the items he remembers.
Kim was an Indian boy trained by the British Army to be a spy. The game was used in the novel to improve his powers of observation.
