Outplay turns one room into a party. Get 2 to 8 friends together, connect over the same Wi-Fi or straight phone to phone, and play 44 quick mini-games that anyone can pick up in seconds. No internet, no sign-ups, no ads. Everything runs on your own phones. PLAY A SHOW Start The Show and play a run of rounds: a race, a survival round, a battle, a grab, and a final worth double points. Pick 3, 5 or 8 rounds, and every show rolls fresh games with random maps. Want a theme? Race Day is all races, Brawl Night is all fighting, Brain Break is all thinking. Or play Endless for random games back to back, build your own tournament, or just jump into one game. RACES & KNOCKOUTS Crash through walls of fake doors in Door Crash, scramble over tipping seesaws in Seesaw Scramble, and clear the obstacle course in Wipeout. Grab the crown at the top of Crown Climb, sled away from an Avalanche, and climb ahead of the Rising Lava. Build the course and race it in Party Parkour, sneak past guards and lasers in Stealth Run, and cross lane after lane of hazards in Lane Rush. SURVIVAL Stay on top of the spinning drums in Roll Out and on the crumbling floors of Layer Cake. Keep your footing in Falling Platforms, Meteor Shower and The Crusher, and dodge the storm in Asteroid Belt. ARENA BRAWL Shove rivals out of the ring in Sumo Smash and Penguin Pushing, pass the lit dynamite in Bomb Tag, dodge the bulls in Bull Chase, claim the wandering hill in King of the Hill and yank rivals into the pit in Tethered. Paint the floor in Turf War, pelt your friends in Snowball Fight, or steal their chickens in Hen Heist. VEHICLES Ram rivals off the arena in Demolition Derby, box them in with Light Cycles, and trade shots in Tank Battle and Sea Battle. Escape the cops in Police Chase, race the circuits in Grand Prix, slide seals down the ice in Slippery Race, and fly Space Rockets. SPORTS & SHOOTERS Defend your own goal in free-for-all Football, throw all at once in Curling Chaos, and fight across seven office floors in Office Shootout. THINK, BLUFF & REACT Outrun a buzzsaw maniac with the right answers in Quiz Chase. Find the fake in Fake Artist, read the room in Wavelength, and remember the tiles in Mind the Tiles. Test your reflexes in Reaction Duel, Stopwatch and Tower Stacker, guess closest in Number Guessing, and sabotage rival anglers in Bomb Fishing. Pick a name, a colour and an avatar, and play. Nothing leaves the room.
