Oh Hell Strategy Guide

Oh Hell rewards one thing above all: predicting yourself. You score only when you take exactly the number of tricks you bid — taking too many is just as costly as taking too few. These tips will help you bid accurately and then steer the play to land on your number. New to the game? Read the full rules first.

1. Count your likely tricks before you bid

Good bidding starts with an honest count of the tricks your hand can realistically win. Three sources of tricks dominate:

High cards in side suits. Aces win almost always; kings win often once the ace is gone. Queens and lower are unreliable unless you also hold the cards above them.
High trump. The ace and king of trump are near-certain winners, and length in trump turns middling trump into winners once everyone else runs out.
Void and short suits. A suit you hold no cards in lets you ruff — win a trick with trump — so each void is a potential extra trick as long as you have trump to spend.

Add those up and you have a baseline bid. Hand sizes change every hand (the deal counts down, e.g. 7, 6, 5, … 1), so in short hands a single high card can be your whole bid, while in long hands trump length matters far more than any one card.

2. Bid accurately, not optimistically

Because the scoring bonus only lands on an exact hit, the cost of overbidding by one is the same as underbidding by one — you lose the bonus either way. That symmetry should make you disciplined, not timid: bid the number you can actually defend, and resist rounding up on hope.

Pay attention to the running total of bids. The dealer bids last and the table can see whether the sum of all bids is over or under the number of tricks available:

If the table is overbid (total bids exceed the tricks available), tricks will be scarce — at least one opponent must miss. Shade your own bid down; the tricks you were counting on may get taken from you.
If the table is underbid (total bids fall short), there are loose tricks floating around that nobody is fighting for. You can often pick up one more than your raw count suggests.

3. The zero bid is a weapon

Bidding zero and making it scores a flat bonus — a great result from a weak hand. A zero is strongest when you are short on trump and hold mostly low cards, so you can duck under every trick. The risk is the endgame: if you shed your low cards too early, you can be forced to win a trick you don't want. Keep your lowest cards for last, and when you must follow suit, play the highest card that still loses.

4. Manage trump deliberately

Trump is your most flexible resource — spend it on purpose. Ruff (play trump on a suit you are void in) when winning that trick advances your bid; otherwise slough a losing card and keep the trump for a trick that matters. If you are chasing tricks, leading high trump early forces opponents to spend theirs, clearing the way for your side-suit winners. If you have already made your bid, do the opposite — hold trump back so you don't accidentally win more.

5. Leading and following with purpose

The player who leads a trick chooses the suit everyone must follow. Use the lead to your advantage:

Need tricks? Lead your guaranteed winners (an ace, or high trump) while opponents still hold cards that must follow and lose.
Avoiding tricks? Lead low cards in suits where you have no winners, and let someone else take the trick.
Watch the void. Once an opponent shows they are void in a suit, leading that suit lets them ruff — useful if you want them to win, harmful if you don't.

Remember you may not lead trump on the first trick of a hand unless your hand is nothing but trump.

6. Play to your bid, every trick

Once cards are out, your only job is to land on your number. Track how many tricks you still need:

Still short of your bid? Compete for tricks — play winners, ruff voids, and force out opponents' high cards.
Already at your bid? Stop winning. Duck under tricks, slough high cards when it's safe, and avoid ruffing. An extra trick you didn't bid is a busted hand.
Protecting a made bid late? Keep one low "exit" card so you always have a card that loses on demand.

7. Beating Screw the Dealer

The Screw the Dealer rule (enabled by default here) bars the dealer from bidding a number that makes the total of all bids equal the number of tricks — so the dealer is forced into a bid the table can attack.

As the dealer: you bid last and see every other bid, so you know the exact number you're forbidden from making. Pick the side — over or under — that your hand can play to most safely, rather than the number you'd ideally want.
As a non-dealer: bidding so the running total sits right at the trick count narrows the dealer's escape routes and pushes them toward an awkward forced bid you can then play against.

8. Common mistakes to avoid

Bidding on hope. Counting a queen or jack as a winner when the cards above it are still out is how you overbid.
Forgetting the bonus is exact. Once you've made your bid, winning "just one more" is a loss, not a bonus.
Wasting trump. Ruffing a trick you didn't need burns a card that could have protected your bid two tricks later.
Dumping low cards too early on a zero bid. Save your escape cards for the end, or the last trick lands on you.
Ignoring the table total. The over/under signal tells you whether tricks are scarce or loose — bid accordingly.

Frequently Asked Questions

What is the best bidding strategy in Oh Hell?

Count your near-certain winners first — aces, high trump, and tricks you can win by ruffing a void suit — then bid that number. Because you score only when you hit your bid exactly, a disciplined, slightly conservative count usually beats an optimistic one. Adjust by one if the total of all bids is far above or below the number of tricks available.

Should I bid zero in Oh Hell?

A zero bid is one of the strongest plays when your hand is full of low cards and short on trump, because a made zero scores a flat 10. The danger is being forced to win a trick late when you run out of low cards, so keep your lowest cards for the final tricks and shed high cards early when you can follow suit safely.

What is the Screw the Dealer rule and how do I play around it?

Screw the Dealer (on by default at ohhell.app) forbids the dealer from bidding a number that would make the total of all bids equal the number of tricks. As dealer you bid last, so you know the running total — use it to choose the side (over or under) you can most easily play to. As a non-dealer, bidding to push the table total close to the trick count squeezes the dealer's options.

When should I play a trump card in Oh Hell?

Play trump to win tricks you need and to win them as cheaply as possible. Ruff a void suit when winning that trick helps your bid; slough a loser instead when you have already made your bid or the trick is going to an opponent anyway. Leading high trump early can flush opponents' trump out so your other winners survive.
