Thread vs Shinshinka

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.

Shinshinka — The Arrow Graph Puzzle Sharpen your mind with Shinshinka, an innovative logic puzzle game that challenges the way you think. Connect the dots, follow the rules, and build the perfect graph — one arrow at a time. How it works Every puzzle is a hidden network of nodes connected by arrows. Starting from A1, each next node must be exactly one step greater — increase the letter, the number, or both by one. Fill in the missing nodes and arrows to complete the graph, making sure every tile is connected and nothing is left empty. Simple to learn. Endlessly challenging to master.
