Beetle Solitaire deals classic two-deck Spider with every card face-up from the start, so nothing hides and skillful play climbs toward a 60% win rate.

Beetle Solitaire is Spider Solitaire with all of its secrets on the table. The game is dealt exactly like classic two-deck Spider — ten piles, with fresh rows of ten cards dealt from the stock — but every single card lands face-up, so nothing is ever hidden from you. The name keeps the creepy-crawly tradition of the Spider family alive, where Scorpion, Wasp, and Beetle all scuttle after the same idea with slightly different rules.
Because every card is dealt face-up, with nothing ever hidden once it hits the table, Beetle rewards planning far more than luck. Play well and you'll win roughly 60% of these two-deck games: it's medium difficulty, and since every card is visible, skill carries almost all of the weight.
For more of that same face-up planning, go to Chinese Spider Solitaire or Scorpion Solitaire next.
If you'd rather deal with cards still hidden, Spider Solitaire is the original game this one strips bare.

8 foundation piles: Each one receives a complete sequence of thirteen cards of the same suit, from King down to Ace.
10 tableau piles: Build down regardless of suit. Groups of cards in descending order and of the same suit can be moved together. The first 4 piles are dealt 6 cards each and the remaining 6 piles are dealt 5 cards each, all face-up.
Stock: Click to deal one card onto every tableau pile. There are 5 deals in total, and you may not deal while any pile is empty.
There are eight foundation piles.
Single cards are never allowed to be moved to the foundation. Only once you've built a complete sequence on the tableau, thirteen cards of one suit in order from King down to Ace, can you transfer it to a foundation pile.
The top card of each foundation can be moved back into play if another pile will accept it.
Ten tableau piles hold the deal. The first four piles hold six cards and the last six piles hold five. Every card is 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 cards that fit on the 7 of spades are the 6 of spades, the 6 of hearts, the 6 of diamonds, or the 6 of clubs.
Groups of cards in sequence down from high to low may be moved from one tableau column to another if all cards in the group are of the same suit.
Any card or movable group of cards can fill an empty slot in the tableau.
The stock is made up of the 50 leftover cards.
When you click on the stock, a card is dealt face-up to the top of each tableau pile. You cannot deal while one or more tableau piles are empty.
