About this game
A deadly multiplayer mind game where Blackjack and R-Roulette collide with powers, betrayals, and luck.
A 4-player online multiplayer experience combining luck, strategy, and betrayal. Play two intense modes: Twisted Blackjack, where players face a corrupted dealer and each other using unique abilities and match mutations; and Russian Roulette, where every decision could be your last. Earn points, buy game-changing Totems, and survive unpredictable rounds.
A deadly game mode where you gamble your life for points and wins.
Face a dealer with one of 3 personalities, each using 7 unique abilities to control the table. Players buy their own loadouts, choosing from 10 powerful abilities, and battle each other while mutations twist the rules every match. Win rounds, earn points, and spend them on Totems to gain the upper hand. Outsmart your opponents, break the dealer, and take control of the game.
A Deadly Sequence Between Blackjack’s Phases
Spend your points between phases in Blackjack to buy powerful totems. Use them to bend rules, counter abilities, or sabotage other players. Every choice shapes the outcome.
A deadly game mode where you gamble your luck and your friends' lives
A brutal multiplayer mode where 4 players spin, choose, and shoot. Spare a life to gain abilities, or pull the trigger and pray. 6 chambers, one winner.

Two Months Since Launch, Thank You All 💙
Wow, 2 months since One-In launched! Time really flew by. Seeing Twitch streamers, random players, and even entire Discord groups having fun with the game has been surreal. I never expected One-In to get this kind of love, and I just wanna say thank you to everyone who gave it a shot.The game turned out to be something I’m genuinely proud of: simple, weird and FUN, exactly how I wanted it. Sadly, there won’t be any more updates, since I’ve lost the project files completely. It sucks, but that’s part of the journey. (new thing I've learnt about back-ups I guess)Still, One-In was a huge step forward for me, and I’m really happy with what it became.💙 Big thanks to everyone who helped make it happen:souls_like aka Alcholist BotBenjiDeutschmanMax (Elmo)EnderfroggGabyPhilip (Iamkiller)OlliRandomdude (Ilyas)Fatal (phyraxisal)You guys were there testing, breaking things, giving feedback, and skyrocketed the development process.🎵 Music composed by: Meal His tracks added so much atmosphere to the game.And the biggest thanks goes to my girlfriend. she made all the 3D models, props, and somehow still puts up with me while I chase these crazy projects. We’re just two teenagers trying to bring life to what we imagine.It’s been a wild ride, but this isn’t the end. I’m already working on something new, a bigger, CrAzIeR PrOjEcT!See you next summer 🏝️🐟🎣Read full article on Community Announcements (Tidecrest Studios)
