How to play Starworm
Steer the worm with the arrow keys, WASD, or a swipe. The field wraps like a torus — glide off any edge and you re-enter the opposite side, so there are no walls to hit. Graze stars to grow longer and speed up as your tail trails behind you.
Every seventh star flares into a timed comet worth +50 points before it fades, so it is worth the detour. The only way to die is to cross your own tail, and that gets harder to avoid as the worm lengthens and the speed climbs.
Tips & strategy
- Use the wrap: leaving one edge to reach food on the other is often the safe line.
- Chase comets early, while your tail is short and the board is open.
- Carve the field in tight lanes so you always leave yourself an exit.
- Speed only rises, so plan your turns a couple of cells ahead as you grow.
