How to play, in one minute

Tap a face-up card that's one higher or one lower than the card on the waste pile, in any suit. It becomes the new waste card, so keep going as long as you can: 6, 7, 8, 7, 6. Clear all three peaks to win.

The complete rules are in our TriPeaks rules, and the TriPeaks strategy tips explain which card to play when you have a choice.

How often can you win?

Almost always, if you could see every card. Our solver, which does see them, cleared 970 of 1,000 random deals and proved the other 30 impossible. That fits the figure Wikipedia quotes from the game's inventor, Robert Hogue: over 90 percent of deals can be solved.

Playing blind is another story. A simple player that sees only the face-up cards, and always starts the longest run it can see, cleared 370 of the same 1,000 deals. On average it finished with 1.8 cards left in the peaks. The difference is all in the face-down cards and the stock order, which is why picking the right card when you have two choices matters so much.

Our own test, October 2026, on the same numbered deals for both players.

Questions

Is TriPeaks free to play here?

Yes. No account, no download and no limit on games. If ads ever appear, they'll stay off the table.

Can every deal be won?

With "Winnable deals only" on (the default), yes: every deal is one our solver has cleared. You can't see the face-down cards or the stock, so you can still get stuck. Undo lets you try another order.

Does suit matter?

No. Only the rank counts. A 9 of clubs goes on an 8 or a 10 of any suit.

What is a run?

All the cards you play in a row without turning the stock. Each card in a run scores one more than the last, so a run of 8 scores 1 + 2 + ... + 8 = 36. The counter above the table shows your current run and your best one this game.

Why is my score below zero?

Each card you turn from the stock costs 5 points, and there are 23 of them after the first. In our test of 1,000 deals, the simple player above finished with an average score of -6.3. Long runs and the peak bonuses are how you get ahead.

What is today's deal?

One deal a day, the same for everyone, always one our solver has cleared. Win it to start a streak.
