Sunthread: One Line Puzzle
Relaxing Logic & Path Drawing
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Wake a sleeping garden with one thread of light. 120 hand-painted logic puzzles, a new Garden of the Day, no timers, no guessing, and it all plays offline.
You are the morning light. Draw one unbroken thread across a sleeping garden, and every tile it touches wakes up.
Sunthread is a calm one-line logic puzzle: visit every tile exactly once and open the numbered flower buds in order, 1 → 2 → 3. Every garden has exactly one solution, and you can always reach it with pure logic. No guessing. No timers.
HOW IT PLAYS
• Draw a single path through every tile of the garden
• Open the numbered buds in order as you go
• Wrong turns gather clouds. Four clouds and the garden falls back asleep, so take a breath and try again
• Stuck? A Ladybird hint shows your next steps
• Want a fresh start? "Deep breath" clears the thread
SIX CHAPTERS, NEW RULES
120 hand-ordered gardens across six chapters, each one adding a new idea:
• Dawn: cover every tile, open the buds in order
• Breeze: a draught carries the light straight through, an eddy forces it to bend
• Fences: hedges block the way and ponds break the square board
• Beds: a badge counts how many separate visits your thread makes to a fenced bed
• Vines: a badge counts how many times the light bends inside a bed
• Golden Hour: everything at once
A NEW GARDEN EVERY DAY
Come back for the Garden of the Day and keep your streak going.
GROW YOUR GREENHOUSE
Every garden you finish grows a plant in your Greenhouse. Earn seeds as you play, with more for finishing with fewer clouds. Season themes repaint every garden: First Light, Cherry Spring, Amber Autumn and Winter Garden.
MADE TO BE SOOTHING
• Hand-painted gouache art and a glowing thread of light
