Sink the Ship is a game of nerve disguised as a game of pouring: a small empty cup floats like a boat inside a big pitcher, and players go around the circle each adding a little more beer to the floating cup. Every pour makes the ship ride lower in the water. Add too much and it takes on beer, tips, and sinks - and the player whose pour sent it under has to drink the entire pitcher, sunken cup and all.

It is the beer-soaked cousin of Jenga and Titanic: pure escalating tension with a single, inevitable disaster at the end. There is no aim, no skill shot, just the slow dread of watching a nearly-full cup wobble as the pitcher comes to you. Do you play it safe with a splash and pass the pressure on, or gamble on a bigger pour to speed someone else's doom? Everyone at the table is one bad decision from finishing the jug.

What you need & setup

Set a large pitcher on a flat, stable table and fill it partway with beer.
Float a smaller empty cup or glass inside the pitcher so it sits upright like a little boat.
Gather 3-10 players around the table and agree on a direction of play.
Give each player their own beer to pour from, or keep a communal bottle to top up from.
Decide the pour rule - free pour or a minimum splash each turn - before the first player goes.

How to play Sink the Ship

Pour into the floating cup

On your turn, pour a small amount of beer into the empty cup floating inside the pitcher - not into the pitcher itself. Each pour adds weight, pushing the little ship lower in the surrounding beer. You choose how much to add, within any minimum your group agreed on. The goal is simple: add beer without being the one whose pour finally sinks it.

Watch the ship ride lower

As the floating cup fills, it settles deeper and deeper until its rim is nearly level with the beer around it. This is where the tension peaks - a cup that is one splash from going under turns every remaining pour into a gamble. Players can lean in and study the waterline, but no touching the pitcher or the cup except to pour.

Sink it, drink it

The moment your pour tips the floating cup enough that it takes on beer and sinks, you are the loser of the round - and you drink the entire pitcher, the beer plus the now-submerged cup's contents. Fish the cup out first so nobody drinks it. It is the whole payoff of the game: slow, shared dread resolving into one person emptying the jug.

Reset and float a new ship

After the pitcher is drained, refill it partway, float the empty cup again, and start a fresh round with the next player. Because the loser drinks a full pitcher, keep the pitcher modest and the pours small so no single round becomes brutal. Rounds are quick, so most groups play several and let the pitcher size set the pace.

Adjust the pour rule to tune the tension

Free-pour rounds let cautious players trickle in a few drops and drag the game out; a minimum-pour rule forces real commitment and ends rounds faster. Switch between them to control how long a pitcher lasts. A larger floating cup survives more pours (longer, tenser rounds); a smaller one sinks fast (quick, savage rounds).

The rules

A small empty cup floats inside a partly filled pitcher of beer.
Players take turns, in order around the table, pouring beer into the floating cup.
Pour only into the floating cup - never directly into the pitcher.
Whoever's pour makes the floating cup sink loses the round.
The loser drinks the entire pitcher (fish out the sunken cup first).
No touching or steadying the pitcher or the floating cup except to pour on your turn.
Agree on a minimum pour per turn, or play free-pour, before starting.
You may not pour so slowly that it stalls the game if a minimum is in force.
After a sink, refill the pitcher, re-float the cup, and the next player starts the new round.
Keep the pitcher modest so the loser's chug stays manageable.
A cup that tips from a bump rather than a pour is a re-float, not a loss - the bumper may owe a penalty sip by house rule.

Variations & house rules

Somaek Titanic

The Korean classic this game descends from: float an empty shot glass in a beer glass and pour soju into the shot glass instead of beer into a cup. When it sinks, the loser drinks the whole mix (somaek). It is the same escalating-pour tension on a smaller, sharper scale, and it pairs a spirit with beer for a stronger round. We have a full Titanic page.

Splits on the sink

Instead of the loser downing the whole pitcher alone, they drink half and choose one other player to split the rest with - or the pitcher gets shared around the whole table. It softens the blow of a full pitcher and keeps big groups from putting one person under a huge volume, while keeping the drama of who sank the ship.

Double or nothing pours

Any player may call 'double' before pouring; they must then pour at least double the current minimum. If the ship survives their pour, the next player's minimum is halved as a reward for the risk. It injects bravado into an otherwise cautious game and rewards players who gamble on a big pour to swing the pressure across the table.

Water ship

Float the cup in water and pour water each turn; the loser takes a set number of sips of their own drink instead of chugging a shared pitcher. You keep the exact same nerve-testing mechanic while every player controls their own alcohol, making it perfect for mixed groups or anyone who does not want to risk a full-pitcher chug.

Pro tips

Pour slow and low - a controlled trickle is far less likely to tip the cup than a sudden glug.

Study the waterline before you commit; if the rim is nearly level with the beer, add the barest splash.

Keep the pitcher only partly full so whoever sinks the ship faces a fair chug, not a punishment.

A wider, lighter floating cup survives more pours - use it for longer, tenser rounds.

Pour toward the center of the floating cup, not the rim, to avoid tipping it sideways.

If your table runs big, agree up front to split the sunken pitcher so no one gets buried.

A little history

Sink the Ship belongs to a broad family of float-and-pour drinking games that turn up around the world, closely related to the Korean somaek game Titanic, where a shot glass floats in beer. Precise origins are undocumented and the game is passed on by word of mouth, so names and specifics vary from group to group. What is consistent is the mechanic - a floating vessel, incremental pours, and a loser who drinks whatever sinks it - which shows up wherever people share a pitcher.

Drink responsibly: Because the loser traditionally drinks the whole pitcher, keep the pitcher small and the pours modest so no single round is punishing - or split the sunken pitcher around the table. Better still, run the water version and take sips of your own drink instead of chugging. Eat first, keep water within reach, and treat the full-pitcher chug as optional, never a dare.

Sink the Ship FAQ

What sinks the cup - too much beer or a bad angle?

Both, and that is the fun of it. Every pour adds weight, so the cup rides lower until it is one splash from going under - but a clumsy, off-center pour can also tip it sideways and swamp it early. The safest pour is a slow trickle aimed at the middle of the floating cup. Once the rim sits near the waterline, even a careful splash can be the one that sends it down.

Does the loser really drink the whole pitcher?

In the classic rules, yes - the player whose pour sinks the ship drinks the entire pitcher. That is exactly why you keep the pitcher modest rather than brimming, and why many groups play the 'splits' variant where the loser shares it around. Always fish the sunken cup out first so nobody swallows it. If a full pitcher is too much for your crowd, switch to the water version or split every loss.

How big should the floating cup be?

A smaller, lighter cup sinks after just a few pours, making rounds quick and savage; a wider, buoyant cup survives many pours for a longer, more agonizing build-up. Match it to your group: fast rounds for a big rowdy table, slow-burn tension for a smaller circle. Whatever you pick, make sure it floats upright and empty before the first pour.

Is this the same as Titanic?

It is a very close cousin. The Korean game Titanic floats an empty shot glass in a glass of beer and pours soju in until it sinks. Sink the Ship scales that idea up to a full pitcher with a larger floating cup and beer instead of soju. The mechanic - incremental pours, an inevitable sinking, and a loser who drinks it - is identical. We have a dedicated Titanic page if you want the soju version.

Can you play Sink the Ship without alcohol?

Easily. Float the cup in water and pour water on each turn; whoever sinks it takes a set number of sips of their own drink - beer, soda, anything - instead of chugging a shared pitcher. The nerve-testing pour-by-pour tension is entirely intact, and every player controls their own intake. It is the ideal way to include non-drinkers or keep a long night manageable.
