Mergecoil: Snake 2048

Mergecoil combines continuous Snake movement with tail-only number merging. Each numbered tile joins the tail. Equal adjacent tail tiles combine, so a tail ending in 8–4–2 can consume another 2 and collapse into 16. That makes route planning and pickup order as important as survival. The browser game supports keyboard controls on desktop and swipes on mobile, with pause and limited undo. No account or installation is required. The site also offers a separate Snake 2048 Arena; this listing focuses on the original grid-based Mergecoil puzzle.
