[6] In 1927, Robert Hülsemann published a description of the game in German under the name Rasender Teufel ("Racing Demon").

[7] Meanwhile, the American "National Nertz Association" blog says it is unaware of any known inventor or specific date of creation for the game, but that it has been around since the 1940s.

[8] Today proprietary Racing Demon cards are produced for it, consisting of ordinary 52-card Anglo-American pattern packs with different coloured backs.

After the cards are returned, the decks are shuffled and set up for the next hand and the process is repeated until a player wins.

[9] The Lake is the central area, used to score points, which any player or team may use by building suited piles in ascending order without doubles.

The River is a 4-columned personal area that a player or team uses by cascading and/or playing cards from columns of alternating color and descending order (like the tableau piles in Solitaire).

The rules for the similar game Pounce, described by Breen in 1934, may be summarised as follows:[6] Each player has a shuffled pack of cards.

Nerts-inspired retail game sets include Ligretto, Dutch Blitz, Solitaire Frenzy, Wackee Six, Nay Jay!
