Wikipedia:Articles for deletion/Kuipers (solitaire)
This is non-notable ( and ).  It is an unknown variant of Klondike_(solitaire), which already covers this genre comprehensively, including notable variants. This variant has virtually no reference to it online or in reputable sources.  Even mentioning it on the Klondike page can't be justified, and it certainly doesn't need its own page.  There are literally hundreds of solitaire card games in existence, and only the most notable ones are included in Wikipedia; so including a non-notable variant ahead of the far more common solitaire games that have already been excluded from Wikipedia can't be justified.  I recommend a speedy delete since this fails Wikipedia's requirements for notability
