If you have five spare minutes, Fruit Blizzard will fill them. Everything happens on one screen with waves of 3-5 flying items with 11% bombs, and the whole thing runs straight in the browser - no downloads, no sign-ups, no fuss.
Swipes are free-form - a long slashing drag can catch three pieces of fruit in one motion, and that is how big combos happen. The gesture also has a cooldown per fruit, so waving the finger around randomly scores less than one committed slash.
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'.
