Accordion Solitaire

A different kind of solitaire.
Accordion Solitaire is a more difficult, more strategic variation of solitaire. Starting with a shuffled deck, you will draw cards and make decisions about how to stack them based on matching ranks and suits. But there are strict rules about when cards can be stacked:
When a stack is adjacent to a matching rank or suit.

When a stack is separated from a matching rank or suit by exactly two other stacks.

The goal of the game is to begin with one deck of cards, and end up with one stack of cards. It will be trickier than you might think!
Features
Multiple Rulesets
Accordion Solitaire features 3 rulesets that change the way the game is played:
Strict
Draw one card at a time, and all possible moves must be made before drawing again.

Relaxed
Draw one card at a time, but you can continue to draw without making all possible moves if you choose.

Free
Draw the entire deck at once and play with full knowledge.

Accessibility
Accordion Solitaire comes with some accessibility features that make it possible for all to play.
Possible move hints
When holding a stack, possible moves will be highlighted to make it easier to understand your options. Defaults to On.

Auto draw
Automatically draw cards until there is a possible move (only applicable when using Strict or Relaxed rules) so you don't have to click the deck manually as often. Defaults to On.

Reduced motion
By default stacks shake when they have possible moves to make it easier to understand your options. If the shaking is distracting or overwhelming, you can force all stacks to stay still. Defaults to Off.

High contrast
Places a color filter over each suit to make it easier to understand when stacks have matching suits. Defaults to Off.

Music & Sound
Fully adjustable Music and Sound sliders allow you to modify volume in-game. Music and Sound can also be enabled or disabled. Defaults to enable Music and Sound, with volume set to 50%.

Tutorial
