If you have five spare minutes, Cobra Blitz will fill them. Everything happens on one screen with a starting step of 85 ms that tightens as you eat, and the whole thing runs straight in the browser - no downloads, no sign-ups, no fuss.
Steering is the whole game: swipes on touch, arrow keys or WASD on desktop. The input queue accepts two turns ahead, which means a well-timed double turn can thread a gap that looks impossible at first glance.
The loop is deliberately compact: one round takes minutes, improvement is visible, and the next run is one tap away. That makes it a reliable filler for short breaks - and an easy game to recommend to someone who 'does not really play games'.
