Noah
The origin of this game is a problem of a man named Noah who lived a very long time ago:
You have to put animals into an ark, always 2 animals of the same kind on neighbouring places. If you have mode "difficult"
selected, then you can put the 2 animals also on places which have only a corner in common. You may not put such animals
which would eat each other on neighbouring places. The "Who eats who" is symbolized by the red arrows.
When you play a new game the program always selects an ark type randomly. The game can be solved for every ark type.
You can use the mouse ( click or "drag" ) to manage the game, but you can also use the arrow and number keys.
Put the last animal into the ark, then the tide is rising!
