TriPeaks Tectonics

Remove all the peak cards by playing any exposed card one rank above or below the top of the waste pile. Drawing slides the plates and rearranges what's reachable.

• Play cards plus or minus one in rank; aces wrap between king and two
• Each draw drifts the plates left or right, exposing or covering cards
• Get stuck with no legal play and the round ends

• Desktop: click an exposed card to play it, use Draw and Undo
• Phone & tablet: full touch support, tap a card to play

• Daily: a seeded deal for everyone
• Practice: a random deal

• Time a draw to slide a needed card into reach
• Use unlimited undo to test how the plates will shift
• Build long up-and-down runs before spending a draw

The clearing rule is TriPeaks as Robert Hogue designed it: remove any exposed card one rank above or below the top of the waste pile, and keep the chain going as long as you can.

Underneath, the ground moves. Each draw shifts the plates, rearranging which cards are exposed — so the layout you were planning against is not the layout you will be playing on.

That attacks the parent game's central skill directly. TriPeaks rewards looking ahead: reading the board for the long chain and spending draws to set it up. When a draw also reshuffles the terrain, planning has to become shorter, and the reliable long chain gives way to taking what is in front of you.

TriPeaks Tectonics adds drifting board mechanics to a classic peaks solitaire. It is an original free browser card game built in-house for PlayPendium.
