Tricky Triangle

One empty hole, one survivor. Now with the Hourglass — three shapes free, 25 boards, one life per climb, and a global top 10. How far can you climb?

Tricky Triangle is the classic peg-jumping puzzle, rebuilt for "just one more board" obsession.

The rule is simple: jump one peg over a neighbor into an empty hole, like a capture in checkers, and the jumped peg is removed. Keep going until a single peg remains. Easy to learn, brutal to master.

But clearing one board is only the beginning.

FIVE SHAPES, TWENTY-FIVE BOARDS Climb Triangle, Diamond, Hourglass, Hexagon, and Star boards, each with five tiers: Easy, Normal, Hard, Extreme, and the white-knuckle Insane.

THREE SHAPES FREE Triangle, Diamond, and the new Hourglass are yours from the first tap — fifteen boards, no purchase, no unlock. The Hourglass narrows to a single waist, so every plan has to squeeze through the middle, and each tier stands taller than the last: five rows up to thirteen. Clear your way onward to earn the Hexagon and the Star.

ONE LIFE PER CLIMB Here is the twist: a climb is a single run. Win and you advance with your score intact. Hit a dead end with no legal jumps left, and the run is over. Every move matters.

STUCK? TAKE A HINT A built-in solver finds a winning move whenever one exists. Double-tap Hint to auto-jump out of trouble. But pride has a price: lean on hints or undo, and your run will not rank.

CLIMB THE GLOBAL LEADERBOARD Clean runs, no hints and no undo, battle for the worldwide top 10. Drop your three initials, arcade-style, and defend your spot. Earn Speedster, Flawless, and No-Hints badges along the way.

KNOW IT BY ANOTHER NAME? Peg solitaire goes by many names: marble solitaire, solo noble, Brainvita, Senku — or simply the triangle peg board game from restaurant tables. If you have ever left one peg standing and felt like a genius, this is that puzzle, with somewhere to go next.

There is always one more board to clear. How far can you climb?
