Tricky Triangle

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.

FOUR SHAPES, TWENTY BOARDS
Climb Triangle, Diamond, Hexagon, and Star boards, each with five tiers: Easy, Normal, Hard, Extreme, and the white-knuckle Insane. Conquer each climb to unlock the next shape.

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.

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?
