A 5-player card game, right in your browser
The real Napoleon,
with nothing to install.
You plus four opponents with real personalities. Bidding, a secret Adjutant, and betrayal — a trick-taking classic brought to the table with the full rules.
In a nutshell
Five players fighting over 20 face cards
in a team-based trick-taking duel.
The Napoleon team (Napoleon + Adjutant) faces the Allied team, battling for face cards across 10 tricks. Can Napoleon hit the number they declared? That gamble is the heart of the game.
The Adjutant is secret. Whoever holds the single card Napoleon names is their ally — but nobody knows who that is until the card hits the table. Every hand becomes a mind game of hunting for allies while hiding your own identity.
Depth · The real rules
From bidding to scoring, the full rules, nothing cut.
Special cards, done right
The Almighty (♠A) is the strongest card. Lead the Joker to make a trump call (choose from three strength levels), plus the Right / Counter Jack and the five-of-a-suit Same-Two — all faithfully recreated.
How bids rank
Highest count wins. On a tie, suit breaks it: ♠>♥>♦>♣. A bold high bid or a safe minimum — reading nerve against caution is what decides the round.
House rules
Trump-free No-Trump (NT), the sweep-all-20 Revolution, Sway (♥Q beats the Almighty), the Joker Call and more — even how you play is yours to choose.
Character · Personality
24 opponents that make every table feel different.
Each personality talks and plays like a different person. Everyone carries three or more lines per moment, and speech bubbles shift with their mood through bidding, key cards, and wins or losses.
* Smoking out the Adjutant is hard too — the real ally and a pure bluff hide behind the very same lines.
