About

Rolling Stone Timer

Features
Read full description

Ready to rock, but can’t get your buzzer working? Don’t panic, because this app has everything you need to get you playing, partying and power-sliding your way through the Rolling Stone game. There’s one setting for the Head-to-Head Round and another for the Charades Round. PLEASE NOTE: This timer is intended to be used with the Rolling Stone Party Game by Big Potato. If you don’t own the game, this app can only be used as a rock-n-roll egg timer (but it would be a very undercooked egg). The Rolling Stone Game is made by Big Potato, an indie board game company from East London. Rolling Stone is a rock ’n’ roll music game that’s not just for music buffs. All you need to know are the names of some very famous bands, and have heard a famous song or two. Split into two teams, then get ready to battle it out and collect as many Artist Cards as you can. To win, you’ll have to survive the shout-out buzzer round, then move onto the charades round, where you’ll be describing bands and humming songs for your team to guess. For those about to play — we salute you.
