Thread is a quiet logic puzzle for people who need a moment. Sort colored dots into matching rows. Rotate and connect pipe segments to form a path through the board. When everything lines up, trace the thread from one end to the other — and feel it click. No timer. No lives. No pressure. Just a puzzle waiting to be solved. WHAT MAKES THREAD DIFFERENT · Two puzzles in one: sort the colors and connect the thread simultaneously · Every puzzle is procedurally generated — infinite variety, always solvable · Swap any dot with any other, or long-hold to rotate pipe pieces · Anchored dots that won't move. Weighted dots that inch forward one step at a time. · A swap limit that gets tighter as you progress — efficiency matters DESIGNED FOR CALM · No ads. No notifications. No streaks. No manipulative mechanics. · Seven handcrafted color palettes inspired by the Pacific Northwest · Original ambient soundtrack composed for the game · Haptics that build to a satisfying crescendo as you trace the final thread · Badges and stats that quietly reward how you play UNLOCK EVERYTHING ONCE The first two tiers are free. One purchase unlocks all current and future content — no subscription, no consumables. Thread is made by Petrichor Games, an independent studio in the Pacific Northwest.

Verdict

The call

The clearest difference is ads: Thread at none against Fill's shown. Fill's advantage is update cadence (every 6 days vs every 2 months) and iOS requirement (12.0 vs 15.6). On price, rating, review sentiment and ratings volume there is nothing between them.
