Accordion

Accordion is a solitaire game using a standard deck of cards. The cards are spread out in a line. You can put a pile on top of its left neighbor or the top of the third pile to the left if the top cards have the same suit or rank. The goal is to compress all the cards into one pile.

In a variant (used if the table is too small) you add the cards one by one and the width cannot exceed the width of the table.
