Oh Hell Odds & Statistics
Most strategy guides are opinion. This page is data — original numbers pulled straight from completed Oh Hell games played here on OhHell.app. How often do players actually hit their bid? Does a zero bid really pay off? Are small hands harder than big ones? The tables below answer those questions from real play, not theory. When you are done, put them to work in the strategy guide.
Data as of July 6, 2026, aggregated from 1,388 completed games (56,702 individual bids across 9,063 hands). Free to cite under CC BY 4.0.
The headline numbers
The single most important number in Oh Hell is not how many tricks you win — it is how often you win exactly what you bid. Across every finished game on the platform, players hit their bid 46% of the time. Everything else on this page is a lever on that one figure.
Bid success by hand size
Oh Hell deals a different number of cards each hand — the classic schedule counts down (7, 6, 5 … 1) and sometimes back up. Hand size changes the problem completely: in a one-card hand your entire fate rides on a single card, while a long hand has far more ways to go wrong. The pattern in the data is clear — smaller hands are easier to bid.
| Cards dealt | Bids | Made exactly |
|---|---|---|
| 1 card | 9,095 | 65% |
| 2 cards | 9,221 | 54% |
| 3 cards | 9,221 | 46% |
| 4 cards | 9,221 | 39% |
| 5 cards | 9,221 | 37% |
| 6 cards | 5,834 | 35% |
| 7 cards | 4,574 | 36% |
| 8 cards | 129 | 29% |
| 9 cards | 93 | 31% |
| 10 cards | 93 | 17% |
Only hand sizes with a meaningful sample (at least 25 bids) are shown, so a handful of unusual deals can't skew a row.
The zero bid pays — the data proves it
Bidding zero and making it scores a flat bonus from an otherwise weak hand, and it is one of the most dependable calls in the game. On OhHell.app, zero bids are made 84% of the time — noticeably better than the 24% success rate on bids of one or more. When your hand looks like the one below, the odds are on your side.
A hand with no card higher than an eight and no trump can follow suit low every trick and hold a cheap "exit" card for the end. The trap is shedding those low cards too soon — see the zero bid in the strategy guide for how to protect it.
When players miss — over or under?
A missed bid can fail two ways: you take more tricks than you bid, or fewer. Of every missed bid in the data, 18% came from taking too many tricks. That is the signature mistake of Oh Hell: it is easier to accidentally win a trick you didn't want than to conjure one you needed, which is exactly why disciplined, slightly conservative bidding beats optimism.
How this was measured
These numbers are aggregated offline from the platform's completed-game history — every finished game contributes its hands, bids, tricks taken, and final scores. A "made" bid means the player took exactly the number of tricks they bid; the winning score is the top final total in each game. Games in progress and abandoned games are excluded, and the figures are recomputed on a schedule and stamped with the data-as-of date above so the page never goes stale.
The dataset reflects real play on OhHell.app, including games with computer opponents that bid and play under the same rules. It is offered free to cite under a Creative Commons Attribution license — a link back to this page is all we ask.
Frequently Asked Questions
How often do Oh Hell players make their bid?
Across completed games on OhHell.app, players take exactly the number of tricks they bid 46% of the time. The rate is highest on small hands, where a single card decides the outcome, and falls as hands grow. Because Oh Hell only rewards an exact bid, that hit rate — not the number of tricks won — is what separates strong players from weak ones.
What is the zero-bid success rate?
A zero bid is one of the most reliable calls in the game. On OhHell.app it is made 84% of the time — better than the 24% rate for bids of one or more. A hand of low cards can duck under every trick; the risk is the endgame, when players who shed their low cards too early are forced to win a trick they did not want.
Where does this data come from?
It is aggregated from completed games played on OhHell.app — every bid, hand size, and final score from finished games in the platform's history. The numbers are recomputed regularly, stamped with a data-as-of date, and free to cite under a Creative Commons Attribution license.
