REEF — how to play

You have a 150 with six slots of live rock and two frags. Everything grows in real time, up to eight hours while you are away — nothing is ever lost and nothing dies.

  • Tap a coral when its ring closes and the READY tag appears: you sell that colony for credits and the slot frees up.
  • Tap an empty slot to plant. Higher tiers need equipment first — montipora and acropora want light 2, torch and goniopora want light 4 and a doser.
  • Credits buy corals, equipment and rock. More rock is more slots: six up to twenty-four.
  • Phosphate rises with every fish you keep. Past 0.15 algae takes slots and growth halves. A water change costs 50 credits and drops it 0.05; a skimmer slows the rise; scrubbing is free (one patch per tap) and a cleanup crew eats it for you.
  • The strip is your ladder — eight tasks, each paying credits the first time you meet it.

Progress saves on this device. Leaving and coming back is the intended way to play.
