At the Ski Lodge, you can play the game Ice Fishing.
Ice Fishing Cheats:
Members can wear the Flashing Fishing Lure Rod when playing Ice Fishing to catch the gray fish. Gray fish give you twice as many coins as yellow fish.
When you start to see the shadow of the big red fish named Mullet, keep a yellow fish on your line. You will see the shadow after you catch 60 fish.
Mullet will come and bite the yellow fish off of your hook. You will get a 100 coin bonus.
