Quiet Threads
Read full descriptionHide full description
Quiet Threads is a cozy grouping puzzle. Each puzzle shows sixteen words. Four of them belong together in a hidden category โ and there are four categories in all. Pick four words that share a theme, tap submit, and the group locks in. Four mistakes ends the round. No timer, no streak penalty, no noise โ just words and time to think. The name borrows the expression "common thread" โ the shared idea that ties a group of words together. How it plays: โข Sixteen words, four hidden categories of four โข Find all four groups in four mistakes or fewer โข A "one away" nudge when three of your four belong but one doesn't โข Difficulty pip per puzzle and a distribution bar per pack so you can pick your pace One daily puzzle per language, picked once and shared by everyone playing that day. Thirteen hand-authored themed packs at launch โ seven in English (Starter, Coast, Garden, Kitchen, Library, Nights, Studio) and six in French. Every puzzle is read by a human and rated for overall difficulty, so packs ramp gently rather than spiking. Two content languages: English and French, with localized words and categories โ not machine translations. Switch in Settings โ Language; daily puzzle and packs follow your choice. Four themes โ Light, Paper, Dark, and Dusk. Pick one in Settings, change it whenever you like. Cozy ambient music and gentle haptics. Every sound has a tap-mute on the Home screen, no settings dive needed. No ads. No accounts. No real-money purchases. Anonymous product analytics only โ no IDs, no personal data, no tracking. Your stats live on this device.

Futoshiki Mastermind's advantage is update cadence (every 10 days vs monthly). On price, device support and iOS requirement there is nothing between them.
