How to play
- Choose Dig or Berm, then drag across the sand to lower it or pile it up.
- Watch your shovel energy, since every change costs some and Undo gives it back before the tide comes in.
- Tap Let the tide in and watch where the water flows.
- Save at least one castle to unlock the next beach, and save them all for three stars.

Tips
- Rocks block water for free, so join your berms to them instead of building a whole wall.
- Crab holes swallow water, so dig channels that lead the tide into them.
- Each tide is higher than the last, so spend the shovel energy you get after each tide raising your berms.
- You can still dig and build while the tide is in, so keep a little energy spare for leaks.
