As any good fisherman will tell you, you should always carry a fish in your pocket, just in case. And now you can. The classic push-your-luck trivia game, Sounds Fishy, is now an app! The game is simple: your friends each make up a fake answer to a ridiculous question, then all you have to do is pick the fake answers without hooking the real one. If you do, you lose all your points. Why trawl through the App Store looking for the perfect trivia game, when you’ve already landed on it? One player buys the Sounds Fishy app, everyone else joins for free using the Big Potato Companion App. Then the game takes care of everything - scorekeeping, turns, and all the fishy fun. It’s the party game where one answer’s real, and the rest are red herrings. - Great for ages 12+ - 750 strange but true trivia questions to play - Two minutes to learn, 20 minutes to play - 3+ players (the more slippery, the better) - The app handles the game - no setup, no cards, no fuss - One player hosts the game with the premium app - Everyone else joins for free via the Companion App How it works It’s so simple to play. Simply download the app, then get your friends to join in on their phones by downloading the free Big Potato app (it only takes a couple of seconds). Now they can use their phones to see the questions too, and go fishing for fakes when it’s their turn.
