Shuffly settles it. Who goes first, who's on whose team, who got the secret role, and who's winning once the game starts. Ten modes in one app. Works offline, no account. PICK SOMEONE • Finger Pick. Everyone holds a finger on the screen and the countdown picks one. No group, no names, nothing to set up, so it works with people you just met. • Lucky Pick. Pull one winner from your group, or several. Recent winners get weighted down so it stops landing on the same person. SPLIT THE ROOM • Pair Up. Random partners, without the same two ending up together every week. Odd number? Make a trio or let someone sit out. • Team Builder. Split a crowd into balanced teams in one tap, each team in its own colour. Drag a name to swap it onto another team. • Shuffle Line. Batting orders, presentation slots, turn rotations, shown as a list or a stadium seating chart. If one spot looks wrong, drag that name where it belongs. • Role Dealer. Deal secret roles from one phone passed around. Presets for Werewolf, Mafia and others scale to your group size, and you can save your own sets. PLAY AND SCORE • Dice. d4 through d20, plus a d% percentile die. Roll several at once, mixed sizes in the same tray. • Darts. X01, Cricket, No-score Cricket and Around the Clock, with checkout suggestions and bust rules handled for you. • Minigolf. One shared scorecard, a live leader crown, an optional stroke cap. • Chess Clock. Two to eight players, each with their own clock, tap zones big enough for a phone lying flat on the table. GROUPS THAT REMEMBER Save the class, the football gang and the board game crew as separate groups and switch in a tap. Toggle someone off and they sit out every mode until you switch them back on. Nobody gets deleted. Each group keeps its own history and stats. THE FAIRNESS ENGINE True randomness has no memory. That's why the same kid ends up first three weeks running. Shuffly remembers past results for each group and weights the next one, so picks, pairs and teams spread out over time. Want a hard rule rather than a nudge? Lucky Pick has a No-repeat toggle that rules the last winner out entirely. BUILT FOR THE ROOM One phone, passed around. No sign-in, no Wi-Fi, nobody installing anything before you can start. Light and dark themes, Dynamic Type and VoiceOver throughout. PRIVATE BY DESIGN Groups, names, results and scores stay on your device. Anonymous usage analytics are opt-in. The app asks once, and Settings lets you turn it off or delete what's been collected. Names, groups and results are never sent anywhere. PRICING Free to download, with 20 sessions you can spend on any mode. No timer, no expiry date. Dice and Finger Pick don't use one up. If the app earns its place, Shuffly Pro removes the session limit for a one-time purchase. No subscription, no ads, Family Sharing included, and modes we add later come with it. Made by a small independent studio in Norway. Questions or ideas: hello@shufflyapp.com
