Your packet keeps driving on its own — you can only TURN (arrows / WASD, mobile: swipe).
Your own trail (your color) is safe. Someone else's trail, the frame or a component = OUT!
DUELL (vs CPU): last one standing wins the round — best of 3. SURVIVAL: 3 CPUs, speed goes up. DUELL (vs Player): 2 players, 1 keyboard (yellow = WASD, magenta = arrows).
POWER-UPS
TURBO: double speed for a short time.
BYPASS: drive over foreign trails for 4 cells.
FIREWALL: absorbs one collision.
FLUSH: removes 15 trail pieces of the opponents.
