About Five-O — the card duel
Five hands at once. Three columns to win. Five-O is a card duel of a new kind: you don't play one hand, you build five at the same time, column by column. Every card you draw is a decision — put it where it shines, or where it saves. All five columns move forward together: you can't bet everything on one. The fifth card of each column is placed face down. Then comes the last draw: discard it, or secretly swap it for one of your hidden cards. Your opponent sees the column you touched, never the card. At the showdown everything flips, hand by hand. Three columns out of five and the game is yours. All five? That's a FIVE-O. The hands are poker hands — pair, three of a kind, straight, flush, full house — but there are no chips and no money: only reading your opponent and a sense of risk. The rules take one game to learn; the tutorial makes you play it. AGAINST THE AI, ANY TIME • Three opponents: Relaxed, Normal, or the Shark, who gives nothing away. • Fast mode: 3 seconds per decision. • The daily challenge: the same deck for everyone, one attempt, a world leaderboard. • The Tournament of Aces: three rounds, single elimination. • The Ascent: ten tiers with objectives, a title at the summit. ONLINE, AGAINST REAL PLAYERS • Quick match: a stranger at your level within 30 seconds, or an AI at your level steps in. • Duels by code, with friends: classic or blitz, single game or rematches. • Four-player tournaments: open (matched by rating, filled with AIs if players are missing) or private. • The Sunday tournament, 9 pm Paris time: everyone online, prizes doubled. • A rating that says who is strong: it only moves in duels against humans. REASONS TO COME BACK EVERY DAY • A daily streak, three quests a day, a weekly league. • A season every month: twelve tiers, coins and exclusive items — avatars, card backs, titles. • Badges you earn, never buy. • A cosmetics shop paid with in-game coins. WHAT FIVE-O IS NOT No real money at stake, no coins to buy, no gambling. The game is funded by ads, with a single, permanent option to remove them. No account to create: you play right away.
What’s new
Version 1.0.3 · Updated October 21, 2026
New: the Summit, the Ascent’s hard mode. Seven tiers to clear in a row with two lives — one loss too many and you start again from the first. A video or a few coins for one last chance, and a fearsome final boss. The “Unstoppable” title awaits whoever beats it.
