TriPeakz is TriPeaks solitaire: three overlapping peaks of cards above a waste pile, and you clear them by taking any exposed card one rank above or below the top card, in either direction and regardless of suit.
The chains are what makes it. A well-planned run can strip a whole peak in one sequence, while starting from the wrong card strands the cards behind it.
Take any exposed card that's one rank above or below the top of the waste pile, in either direction and regardless of suit. Each card taken becomes the new top, so long chains are possible.
Because starting a chain from the wrong card can strand the cards behind it. Planning the sequence before the first click is what avoids it.
