About this game

Snake, but every choice is life or death. COILBOUND fuses the classic snake game with a modern roguelike: your length is your health, your ammo, and your score — all at once. Do you spend it, or hoard it?

Steer freely with a smooth on-screen joystick, chase glowing fruit, and grow. But the longer you get, the more the arena fills with the deadliest thing on the board — YOU. Cross your own tail and you SEVER, dropping your lost length as edible husks. Turn around and eat them back… if you dare thread your own coiling body at speed.

When you get too big to control, you MOLT: shed down to a small, fast serpent and come back permanently stronger, with a bigger score multiplier every time. That is the whole game — a constant, delicious gamble between greed and control.

FEATURES
• Free 360° movement — a true snake.io-style serpent, not a stiff grid crawler
• The Molt loop — shed length for permanent power, ride an ever-climbing multiplier
• Gorge for glory — push past the line for huge rewards, but a single self-bite is now LETHAL
• Dozens of relics, fangs, and fruit that combine into wild build synergies
• The Descent — a roguelike campaign of procedurally assembled chambers, objectives, and biomes
• The Spire — endless mode built for high scores and the molt engine
• The Gullet — an endless-runner mode where a closing Maw eats your tail from behind
• The Vivarium — a permanent upgrade lab; splice your serpent lineage stronger
• Broods — wild serpent variants, each a completely different ruleset
• Collect and discover over 140 strains in the Index

FAIR BY DESIGN
• No ad ever interrupts a run — ever
• No energy bars, no lives, no wait timers
• Rewarded ads are 100% optional — you choose them for a bonus, never a toll

• Plays fully offline

Chunky neon art, buttery movement, and a one-more-run hook that does not let go. If you love snake games, arcade high-score chasers, or roguelikes like Slay the Spire and Balatro, COILBOUND was built for you.

Grow. Coil. Molt. Survive yourself.
