You're a runaway ball of yarn, and the thread you leave behind is the one thing that can end your run. Hold to curl, release to roll straight, and thread your way through tighter and tighter tangles. Yarnboy is a one-thumb arcade game about nerve and timing. The longer you last, the more thread you lay down — and the less room you have to move. One clip of your own tail and it's over. How long can you keep the yarn rolling? FEATURES • One-thumb controls — hold to curl, release to roll straight, double-tap to pounce • Easy to learn, genuinely hard to master • Collect yarn balls and spend them in the shop • Optional rewarded videos for a second chance or bonus yarn — never forced • Global leaderboard — sign in with Apple or Google to compete • Daily Tangle: a fresh challenge every day • Play fully offline as a guest — no account required No pop-up ads. No paywalls. Just you, one thumb, and a very long thread.
