Mergecoil is a free Snake 2048 puzzle in the browser. Steer a moving snake, collect numbered tiles and set up matching tail segments: merges shorten the snake and reopen space, so pickup order matters as much as steering.
Use arrow keys or WASD on desktop, or swipe on mobile. Collect matching numbers at the tail to trigger chain merges and reach 2048 while leaving an escape route. Press P or Esc to pause; U uses an available undo charge.
