Looplet: Tangle to One Line

Every puzzle starts as a tangle of coloured loops. Tap the crossings to join them, and turn the tangle into one continuous line: a sikku kolam, drawn around its dots.

ONE TAP, MANY CROSSINGS A tap flips a crossing: where two loops meet, they join. But in most puzzles a tap also flips its twin, mirrored or turned round the board, so a tap that joins loops in one place can split them in another. Hold a finger on a crossing first: rings show everything it would flip, and the loop count shows what it would leave. Looking is free. Every tap counts.

A NEW PUZZLE EVERY DAY The same daily puzzle for everyone, with a streak to keep (one missed day a week is forgiven). Want more? The day's hard puzzle is bigger and deeper.

LEVELS WITHOUT END Level 1, 2, 3 and on, for ever, each a little harder: small gentle boards first, then deep 7 × 7 boards and diamonds. Level 214 is the same puzzle for everyone.

THE JOURNEY Hand-picked puzzles in chapters that teach the game a step at a time: first knots, linked taps, diamonds. Then, with Looplet Pro: four at once, the masters, long boards and the grand masters.
