I lost  a lot of  money in "fishing machine". 
Fishing machine is an equipment about fishing game with gambling.
there are many kinds of fishes  in the game.
These fishes always swiming, you can try to shot nets for catch them.
If you catch a shark,you can win 3000 scores. then you can exchange you scores for cash.
Of course, you have to purchase enough fishing nets first.
you can win much money but lost more money in a very short time.  
Have you play this game?
