Interval Solitaire

Build card sequences with different intervals to win the game!

Introducing Interval Solitaire, a game designed to enhance your skills in mental planning, foresight, counting, and arithmetic!

Interval Solitaire is a solitaire card game played with a standard pack of 52 cards.

From this deck an ace, two, three, and four of any suit are laid out as the foundations.

The ace foundation is to be built up in sequence until the king is reached, regardless of suit.

The other foundations are similarly built up, but by twos, threes, and fours, respectively, until they each reach a king:

- Ace -> 2 -> 3 -> 4 -> 5 -> 6 -> 7 -> 8 -> 9 -> 10 -> Jack -> Queen -> King

- 2 -> 4 -> 6 -> 8 -> 10 -> Queen -> Ace -> 3 -> 5 -> 7 -> 9 -> Jack -> King

- 3 -> 6 -> 9 -> Queen -> 2 -> 5 -> 8 -> Jack -> Ace 4 -> 7 -> 10 -> King

- 4 -> 8 -> Queen -> 3 -> 7 -> Jack -> 2 -> 6 -> 10 -> Ace -> 5 -> 9 -> King

The tableau, initially empty, consists of four piles of cards below the four foundations.

How to Play

A single card is turned up from the stock and played either to the top of any of the four tableau piles, or onto one of the foundations if possible.

The top card of any tableau pile may also be played onto one of the foundation piles if it is the next number in the appropriate sequence for that foundation.

The game is won when all cards have been played onto the foundations, and lost when no further play is possible.

The key to using the tableau piles is to focus on putting cards in the tableau piles in reverse order.
