Two decks, twelve three-card piles, and suit never matters: stack up or down by rank alone as the stock refills every empty gap.

Barricade A Solitaire is a simple, two-deck game: you build regardless of suit on both the tableau and the foundations, using a stock but no waste pile.
There are two different games called "Barricade," and Barricade B Solitaire is only a distant relative of this one.
If you run into anything odd or have an idea that would make the game better, please contact me.
Enjoy!
There are eight foundation piles.
Any ace in the foundation may be transferred to any vacant pile.
A card can be added to a foundation pile only if it's one rank higher than the pile's current top card, regardless of suit, so the only card that fits on a 6 is a 7. There can be no more than 13 cards in a pile.
The top card of each foundation can be moved back into play if another pile will accept it.
Twelve tableau piles of three cards each, all dealt face-up.
A card can be added to a tableau pile only if it's one rank lower than the pile's current top card, regardless of suit, so the only card that fits on a 4 is a 3.
Cards on the tableau that are not covered by another card are free to be played onto the foundation or any other tableau pile.
When a tableau spot empties out, it's refilled right away from the stock. Once the stock runs out, any card can fill an empty spot.
Only one card may be moved at a time; sequences are not permitted.
The stock is made up of leftover cards from both decks.
The top card of the stock is always face-up, so you may drag it to the tableau or the foundation whenever you like.
