How to play Flow Race

Water starts at the tap at the top and runs down the pipes into the tanks. Pick the tank you think fills up first. The moment you pick, the tap opens and the race plays out, so you see at once whether you were right.

From easy to hard

  1. Easy Levels 1 to 5: two or three tanks, then tanks of different sizes and a junction inside a junction.
  2. Medium Levels 6 to 10: four tanks, dead ends that take no water, and the first closed valve.
  3. Hard Levels 11 to 15: drains that waste their share, pipes that stop just short of a tank, five tanks.
  4. Expert Levels 16 to 20: two pipes into one tank, and tanks that leak.
  5. Master Levels 21 to 25: basins that must fill before the water goes on, then every catch at once.
  6. Grandmaster Levels 26 to 30: a clock on your pick, from 30 seconds down to 22.
  7. Legend Levels 31 to 35: from 20 seconds down to 12, and the closest races.
  8. Endless Level 36 and up: ten seconds to choose, no end.

Is it luck?

No. Every race follows the same few rules, so a careful look always finds the winner. From level 7 on, most races hide a catch that decides them, the races get closer every level, and the table after each race shows exactly why a tank won.
