Finally WATOR, the hit computer game originally described by A.K. Dewdney, comes to the iPhone!

On the rectangular planet WATOR, there are two life forms: fish and sharks. Each behaves by its own set of rules.

Fish Rules:
- Every “day,” each fish will try to move to an adjacent empty cell.
- If it’s been long enough since it last reproduced, then it will reproduce by creating another fish in its original cell.

Shark Rules:
- Every “day,” each shark will try to eat a fish in an adjacent cell.
- If there are no fish to be eaten, then the shark will try to move to an adjacent empty cell.
- If it’s been too long since the shark last ate, it will starve to death.
- If it’s been long enough since it last reproduced, then it will reproduce by creating another shark in its original cell.



Here’s the kicker!

You get to control these parameters:
- The initial percentage of fish
- The number of “days” until fish get to breed
- The initial percentage of sharks
- The number of “days” until sharks starve
- The number of “days” until sharks get to breed

It’s all up to you!
Try to get your ecosystem to stay alive for fifteen years!
