Compress the entire deck (like an accordion) until only the topmost card is visible.
All cards are dealt out in a continuous sequence.
A card can be placed onto another card immediately to its left, or separated to its left by two cards IF the cards share the same suit OR rank.
Example: If you have 5 of Spades, 8 of Hearts, 3 of Clubs, and a 5 of Clubs…
You could compress the 5 of Clubs onto the 3 of Clubs (getting rid of one card) OR you could compress the 5 of Clubs onto the 5 of Spades (getting rid of 3 cards). If you move the 5 of Clubs onto the 5 of Spades, you will be left with only the 5 of Clubs. The cards are moved to fill in gaps.
*To compress cards, first tap the card on the right, then tap the card to its left that you want the first card to cover.
The game is won when all of the cards have been compressed and only 1 card remains on the screen.
