Description by Ali Mert Gulec(from the App Store)
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 • Adaptive music that follows your thread • Gentle haptics and a high-contrast mode • Plays fully offline on iPhone and iPad, with no account needed • No energy or lives system, and no subscription
Sunthread is free to play. It has optional rewarded ads and a few well-paced ads after wins, with none during your first 15 gardens. In-app purchases include a Supporter Pack that removes forced ads, seed packs and season themes.
Each subscription will automatically renew 3 days before the expiration date for
the same time period. Subscriptions can be cancelled at any time before the renewal.
