Worm Coil: io Arena Snake
Slither, coil, eat, outlast
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Grow longer. Coil tighter.
Worm Coil is a single-player .io arena dialed up. Eat glowing food, slither past clever bots, and grow into the longest worm on the field — all in matches that start instantly with no lag, no waiting, no cheaters.
Three cinematic map themes. Eighteen base skins. Persistent fading worm trails painted across the arena floor. Iridescent body shimmer. Reactive ambient particles that part as you pass. Combo kill banners, camera shake on big eats, and a cinematic chromatic-aberration death you'll actually want to see.
Features:
• Three map themes — Void, Sunset, Cyber
• 18 base skins across six palettes and four patterns
• 6 premium skins via the Galaxy Pack and Royal Pack
• Combo kill system with banner flashes
• Persistent fading trails — no other arena worm has them
• Iridescent shimmer on your worm's body
• Power-ups: Magnet, Shield, ×2 Score
• Game Center leaderboards: Longest Worm, Endless Survivor, Hungriest Worm
• 9 Game Center achievements
• Daily login streak with cycling coin rewards
• Haptic feedback on every kill, eat, and pickup
• Two-finger boost — sacrifice length for speed
• Always-instant matches — bot opponents, no servers, no waiting
