The short version
Pyramid and TriPeaks are the comfort-food solitaires: pretty layouts, short games, easy to pick up. But under the hood they're built on two completely different ideas — one is about pairing, the other about sequencing.
How each one works
Pyramid deals 28 cards in a pyramid. You remove exposed cards in pairs that sum to 13 (a 5 with an 8, a 4 with a 9; Kings are worth 13 and go alone). The catch is that a card is only available once both cards covering it are gone, so the order you clear things in decides whether the partner you need ever comes free. TriPeaks deals three overlapping peaks. You clear one exposed card at a time by taking any card exactly one rank above or below the top card of your waste pile — and rank wraps, so a King can follow an Ace. String those together and one move flows into the next.
The feel of each game
Pyramid is the more deliberate of the two — a small optimisation puzzle where you're constantly asking "if I take this, do I strand its partner?" TriPeaks is the more kinetic: when a streak gets going it's genuinely exciting to watch a single run peel cards off all three peaks. Pyramid rewards foresight; TriPeaks rewards spotting the longest chain.
Difficulty and winnability
Both are stock-limited, so both include deals that simply can't be cleared — that's the nature of these games, not a flaw. TriPeaks often feels more forgiving because one good streak clears so much at once, while Pyramid can lock up when a needed partner is buried. Skilful order of play wins many marginal hands in each. The Pyramid strategy and TriPeaks strategy guides show how, and are solitaire games winnable? covers where they sit overall.
Which should you play?
Pick Pyramid for a thoughtful little pairing puzzle, and TriPeaks when you want quick momentum and satisfying streaks. They're different enough that most people enjoy keeping both around for a spare few minutes — and if you'd rather a game where every deal is guaranteed beatable, try Sudoku or Mahjong instead.
Frequently asked questions
What is the main difference between Pyramid and TriPeaks?
Pyramid is a pairing game: you remove pairs of exposed cards that add up to 13. TriPeaks is a sequence game: you clear cards one at a time by picking any exposed card exactly one rank above or below the card in your waste pile, building long streaks.
Which is easier to win?
TriPeaks tends to feel more winnable because a single good streak can clear large chunks of the board, and rank wraps from King to Ace and back. Pyramid is often tighter — the matching partner you need can get stranded — though both are stock-limited and include deals that cannot be cleared.
Which is faster?
Both are quick — a round of either usually takes only a few minutes, which is what makes them great for a short break. TriPeaks often plays a touch faster once a streak gets rolling.
