The goal of the game is to clear all the cards from board by tapping the face up card that is either one above or below in rank than of the top card on waste cards at bottom.
If there is no possible move, tap on the deck to get a new card. You can play cards in ascending or descending order e.g. 3, 4,5,4,3
Aces can be high or low. Like this K, A, 2, 3 is a possible sequence.
In this game the card colour and suite does not matter only you need to tap on face up card which rank is one up or below the top card on waste pile.
