This is a fishing simulation from German origin.
The player first has to pick a starting location from 60 different locations from all over the world. After choosing a location, the background and boat are fixed and the player can concentrate on using his gear.
Caught fish generates point (based on size and sort) with which additional equipment can be bought and other locations be unlocked.
The game can be minimized and will then notify the PC user every time a fish nibbles on the bait, so he can jump back to the action.
