Tri Peaks Solitaire

Tri Peaks solitaire — also called Tri Towers or Three Peaks — is one of the most visually distinctive solitaire variants. Its playing field looks like a mountain range: three pyramid-shaped peaks rise from a row of face-up cards. Players dismantle the peaks from top to bottom.

The game was invented by Robert Hogue in 1989 and first published digitally by Microsoft in Windows Entertainment Pack 3. Unlike most solitaire games, Tri Peaks is driven by chain building rather than suit organization. Each card you play must be one rank higher or lower than the top card of the waste pile. A chain might run: 7, 8, 9, 8, 7, 6, 7, 8 — freely zigzagging up and down in rank.

This mechanic creates a satisfying flow-state experience. Landing a long chain feels like solving a puzzle in one smooth motion. The original Microsoft version rewarded consecutive plays with bonus points, reinforcing the chain-hunting strategy.

Tri Peaks is grouped with Golf solitaire in the sequence building family. Both games remove cards by rank adjacency rather than suit. But Tri Peaks adds a spatial layer — the pyramid layout means cards are blocked by overlapping cards above them, which Golf lacks.

Modern mobile versions of Tri Peaks are enormously popular. Games like Solitaire Grand Harvest and Tri Peaks Solitaire have hundreds of millions of downloads. The core mechanic works exceptionally well on touchscreens, and short sessions suit mobile habits perfectly.

Tri Peaks Scoring

The original Windows Entertainment Pack 3 scoring formula rewards consecutive plays heavily. Each card cleared in a chain scores 1, 2, 3, 4… points sequentially — so a 7-card chain scores 1+2+3+4+5+6+7 = 28 points, while clearing the same seven cards across seven separate chains scores only 7. This triangular-number reward turns chain-building from a stylistic choice into the central strategic question. The first two peaks cleared award 15 bonus points each; the third (final) peak is worth 30 points. Skilled players routinely produce chains of 20+ cards on favorable deals.

Why Tri Peaks Dominates Mobile

Three factors made Tri Peaks the mobile solitaire winner. Sessions average under five minutes — short enough for ad breaks and commutes. The 55% win rate keeps players engaged without grinding losses. The chain mechanic produces a satisfying dopamine release each time a long run completes, which freemium games like Solitaire Grand Harvest exploit through booster mechanics and progression meters.

1. Shuffle a standard 52-card deck. Deal 28 cards into three overlapping pyramid peaks. Each peak has three rows: 1 card on top, then 2, then 3. The three peaks share a bottom row of ten cards, so the tableau overlaps in the lower portion.
2. Face-down cards in the upper rows become available only when all cards overlapping them from below are removed.
3. Below the three peaks, deal a row of ten cards face-up. These are immediately available for play. The remaining 24 cards form the stock pile, placed face-down. Turn one stock card face-up to start the waste pile.
4. On each turn, play any available tableau card to the waste pile if it is exactly one rank higher or lower than the current top waste card, regardless of suit. Rank wraps in some rule sets (King connects to Ace), but not in others — check your specific version.
5. If no available card is one rank away, draw one card from the stock to the waste pile and try again. The stock cannot be redealt. The game is won when all 28 tableau cards are removed. Cards left in the stock or waste pile do not need to be cleared.

• Build long chains. Every stock draw costs you a card and can break a chain. Scan all available tableau cards before drawing to spot plays you may have missed.
• Clear blockers first. A single card near the base of a peak may be locking two or three higher cards. Removing it efficiently exposes new plays and extends chains.
• Open cards, not just chains. When two valid plays exist, choose the one that exposes more available cards on the next move — not just the one that continues the current chain. Sustainable play requires refreshing the pool of playable cards.
• Watch rank density. If many 8s and 9s are visible but few 5s and 6s, plan your waste pile top card to exploit the concentrated ranks.
• Track your stock. When running low on stock cards with many tableau cards still in place, shift focus to clearing the most-blocked areas immediately rather than hunting for perfect chains.

Tri Peaks was designed by Robert Hogue in 1989 and first appeared commercially in Microsoft's Windows Entertainment Pack 3, released in 1992. Unlike many solitaire games whose origins are lost to the 18th or 19th century, Tri Peaks has a known modern inventor and a clear digital-first history. Hogue designed it specifically for shorter sessions and a scoring system that rewarded skilled chain play.

The game gained wide recognition through Windows entertainment packages throughout the 1990s. When mobile gaming exploded in the 2010s, Tri Peaks proved to be one of the solitaire variants best suited to the medium. Games such as Solitaire Grand Harvest, Tropical TriPeaks, and TriPeaks Solitaire by MobilityWare together accumulated hundreds of millions of downloads — making Tri Peaks one of the most commercially successful solitaire games of the digital era, rivaling even Klondike on mobile platforms.
