A while ago I stumbled on this Flash game:

The objective is simple: you have to build a sand castle. When your done the tide comes in. It is all about how long your castle resists those waves.

Simple but mind bugging. My top score is 863.

I wonder if you can get an higher score. Please post your buildings here if that's possible.

The top 5 says the high score is 2700. I think someone hacked that score.

Try it. Dutch residents can win a Ipod shuffle.

Hah! I got 939 on my second (and last) try! Pretty fun game!

wow! I wonder what castle you build to achieve that score!

I used many of those "wall" things to cover up my (small) building. I also built it as high up as possible. I scattered some small things here and there.
