STRIANGLE
Classic
Most triangles wins
The original duel of wits. Claim triangles, chain them for combos and never leave a free one. Two to four players.
Stretch. Claim. Win.
The chain triangle game on your phone, the one some call triangle chess. Stretch a rubber band between two pegs, close a triangle to claim it, and outsmart the island rivals, or the whole world.

How to play
Easy to learn. Hard to put down.
One gesture, one rule, endless tactics. A match takes about five minutes; mastering the chains takes a little longer.
- Drag!
Stretch a band
Drag from one peg to another to stretch a band. Short bands are unlimited; long ones, two pegs across, are precious.
- ×2.5 combo!
Close triangles, chain claims
Place the last side of a triangle and it is yours: +1 point, and you play again, up to three claims in a row, with a combo that climbs to ×3.5.
- Sun Star!
Find the surprises
In Chaos mode, “?” bubbles hide toys: a Sun Star worth 3, a Pop Buddy that pops the triangle, a Y-Swap that steals one from a rival.
When no band fits anymore, the most points wins. Never give a free triangle.
The real game
A board that fits your hand
These are screens of the actual game: big, clear pegs, a view that turns to fit your screen, and messages that never cover the board.
- One finger plays
- Pinch to zoom
- Twist to turn
- Double-tap to reset
Three modes
One board, three ways to play
Keep it pure, race to the finish, or let the toys loose.
Original 21
First to place all 21 pieces
A race! Every triangle you close places one Y piece from your tray. One band per turn, no extras, empty your tray first to win.
Chaos
Surprises under “?” bubbles
Nobody knows what hides where until the triangle closes: a Sun Star worth 3, a Pop Buddy that costs 2 and pops the triangle, or a Y-Swap that steals from a rival.

A neutral age question comes first. Children play with no ads at all, and nobody sees personalised ads before 16.
Ask a grown-up
For a child, signing in, playing online, sharing or rating the game first asks a grown-up, a quick multiplication.
