A sunny day at the beach. Sandcastles were built and now two tasks remain to complete the work:

1. Dig water channels such that each castle is on its own island.

2. Put all seastars in the water by digging water channels at their positions.

The playfield is a 8x8 grid. Outside this grid is water. You slide around geometric shapes. Where these shapes cover sand the digging takes place. A level is solved, if through the current diggings, the tasks 1 and 2 are fulfilled. Then, where the digging tapped water, the channels are filled.

Note that you do not see the effect of the diggings until a solution is achieved.

Please read the description of rules in the game (HELP from main menu).

Hints: The following will help you to get started: In level 1 slide the lower shape upwards. The effect is a channel of water around the upper right sandcastle and both castles are on their own island. In level 2 slide the shapes around until they cover all seastars. Then all seastars are in the water and both castles are on their own island.

Two important rules to recognize are

A) Two stretches of sand which touch in one point are still connected, meaning, they belong to the same island.

B) Two channels which touch in one point can be crossed at this point. There is no water flow between the channels through this point.


You move the digging tiles by mouse or touch. You click/touch them and flick them in the desired direction. The game cannot be played with keyboard.

In a level, at the bottom of the page, there are three icons to be clicked/touched: Exit the current level, reset the current level and take back a move.

For navigation in menus, following keys are supported:

left cursor key - left in menus
right cursor key - right in menus
up cursor key - up in menus
down cursor key - down in menus
Esc or B - back (in a level it aborts the level)
Return - selects in menus or if nothing to select back


Some levels have only one solution, other levels have multiple solutions.

Find below also an Android version which is just the web version wrapped utilizing crosswalk (therefore quite large memory footprint). Requires Android >= 4.4 to run.
