TriPeaks Solitaire
How to play
TriPeaks uses one deck. Twenty-eight cards form three peaks that share a bottom row of ten cards, and only that bottom row is face up at the start. One card is turned face up onto the waste and the other 23 cards wait in the stock. The goal is to clear all three peaks.
You may move an uncovered face-up card from the peaks to the waste when it is one rank higher or one rank lower than the waste card, whatever the suit. Ranks wrap around, so a King can follow an Ace and an Ace can follow a King. Each card you play becomes the new waste card, which lets you build long chains such as 5, 6, 7, 6, 5. When both cards covering a face-down card are gone, that card turns face up and can be played.
When no card fits, click the stock to turn its next card onto the waste. The stock is used once and does not come back, so a deal is lost when the stock is empty and no card in the peaks fits the waste. The game is won when every card of the three peaks has been played to the waste. This version does not keep a point score and records moves and time instead.
Controls
Tap or click an uncovered card to play it onto the waste, or drag it there with the mouse or a finger. A card that does not fit gives a short shake and stays in place. Click the stock below the peaks to turn the next card. Undo takes back moves one at a time with no limit, and Hint outlines a card that fits, or the stock when none does, in yellow. Every deal has a number shown as Game #N, Restart deal plays the same cards again, and adding ?deal=N to the page address opens that exact deal.
