Trick-Taking (Exact-Bid / Oh Hell family) · India and Nepal (South Asia)
Kachuful (Judgement)
Also known as Judgement · Judgment · Oh Hell · Kachu Full · Kachufool · Forecast Whist · Nomination Whist
Kachuful, known internationally as Judgement, Oh Hell, or Forecast Whist, is a fast, tense trick-taking card game wildly popular across India and Nepal. Played by 3 to 7 people with a single 52-card deck, its genius lies in one cruel twist: before each round you must predict the EXACT number of tricks you will win, then deliver on that promise. Win too many tricks or too few and you score nothing at all for the round. The game's name is itself a clever Gujarati mnemonic for the order in which the trump suit rotates each hand: Ka (Kari = Spades), Chu (Chukat = Diamonds), Fu (Falli = Clubs), L (Lal = Hearts), literally meaning "raw flower." What makes Kachuful so addictive is its constantly shifting difficulty. The number of cards dealt changes every round, the trump suit cycles to a new suit, and the dealer's bid is restricted so the table is always either over-bid or under-bid, meaning someone is guaranteed to fail. It is a perfect mix of probability, card-counting, bluff, and table reading, simple enough to learn in five minutes but deep enough to argue about for years. Whether you call it Kachuful, Kachu Full, Kachufool, or Judgement, the heart of the game is the same: judge your hand honestly, bid with conviction, and hit your number exactly.

How to play Kachuful (Judgement)
- Gather 3 to 7 players, one standard 52-card deck, and a sheet to track scores. Decide on your deal pattern (down to one card and back up, or just down to one) and a single scoring method before you start.
- Deal the starting hand for the first round, then note the trump suit using the Kachuful rotation: Spades, Diamonds, Clubs, Hearts, cycling each round. Everyone can see the trump before bidding.
- Starting with the player left of the dealer and going clockwise, each player bids the exact number of tricks they think they will win. Zero is allowed. The dealer bids last and may not make the bids total exactly to the number of tricks available (the hook rule).
- The player to the dealer's left leads any card. Going clockwise, each player must follow the led suit if able; if not, they may play any card, including a trump.
- The highest trump wins the trick, or if no trump was played, the highest card of the led suit wins. The trick winner collects it and leads the next trick. Repeat until all cards are played.
- Compare each player's tricks won against their bid. Award points only for exact matches (commonly 10 + tricks bid, or 1 per trick plus a 10-point exact bonus), and 0 for any miss.
- Pass the deal clockwise, reduce or increase the hand size per your pattern, advance the trump suit, and play the next round. After the final round, the highest cumulative score wins.
Kachuful (Judgement) rules
Players, Deck, and Card Ranking
Kachuful is played by 3 to 7 players using one standard 52-card deck (no jokers). Each player plays for themselves; there are no fixed partnerships. Cards rank in the normal order from high to low: Ace (high), King, Queen, Jack, 10, 9, 8, 7, 6, 5, 4, 3, 2 (low). The Ace is always the strongest card of its suit. A trump suit is designated each round, and any trump card beats any card of a non-trump suit. The game is best with 4 to 6 players, but the rules scale cleanly from 3 up to 7.
The Deal and the Changing Hand Size
Players take turns dealing, with the deal passing clockwise each round. The signature feature of Kachuful is that the number of cards dealt changes every round. In the most common format the deal starts at the maximum hand the deck allows (often 10 cards each for 3-5 players, 8 each for 6 players, or 7 each for 7 players, so the deck is not exhausted), then decreases by one card per round down to a single card each, before climbing back up to the starting hand size. This descending-then-ascending pattern produces roughly 13-15 hands in a full game. A popular alternative simply starts at the largest possible deal and counts down to one card. Because the hand size shrinks and grows, every round is a genuinely different puzzle.
Determining and Rotating the Trump
After the hands are dealt, a trump suit is set for the round. The defining Kachuful convention is a fixed rotation that gives the game its name: Spades, then Diamonds, then Clubs, then Hearts, cycling round and round as the rounds progress (Ka = Kari = Spades, Chu = Chukat = Diamonds, Fu = Falli = Clubs, L = Lal = Hearts). Because the order is fixed and announced in the name, everyone always knows the trump before bidding. A common variant in the wider Oh Hell family instead turns up the top card of the remaining deck to choose trump randomly, and some rounds (especially the one-card 'no trump' hand) may be played with no trump at all. Pick one trump convention before you start so the whole table agrees.
Bidding the Exact Tricks (and the Dealer's Hook)
This is the soul of the game. Starting with the player to the dealer's left and moving clockwise, each player announces exactly how many tricks they expect to win that round. You cannot pass; everyone must bid a number, and zero is a perfectly legal and common bid. Crucially, the dealer bids last and is bound by the 'hook' (or screw) rule: the dealer may NOT bid a number that would make the total of all bids equal the total number of tricks available that round. This guarantees the round is always over-bid or under-bid, so at least one player is mathematically doomed to miss. Bids are made openly and cannot be changed once the next player has bid. (Some groups instead bid simultaneously using fingers; agree on the method first.)
Playing the Tricks
The player to the dealer's left leads the first trick and may lead any card, including a trump. Play proceeds clockwise. Each player must follow the suit that was led if they hold a card of that suit. If you have no card of the led suit, you may play anything, including a trump or a card of a different suit. A trick is won by the highest trump played in it; if no trump was played, the highest card of the suit that was led wins. The winner of each trick gathers it face down in front of them (so trick counts stay clear) and leads the next trick. Play continues until all cards in the round have been played, after which everyone compares the tricks they actually won against the number they bid.
Scoring: Hit Your Bid or Get Nothing
The most widely used scoring method rewards only exact bids. If you win exactly the number of tricks you bid, you score 10 points plus the number of tricks you bid (so a correct bid of 0 scores 10, a correct bid of 1 scores 11, a correct bid of 3 scores 13, and so on). If you take even one trick more or fewer than your bid, you score 0 for that round, no matter how close you were. A second very common method gives 1 point per trick won plus a 10-point bonus for an exact bid, which still rewards accuracy but softens the all-or-nothing sting. Scores accumulate across all rounds, and the player with the highest total at the end of the final round wins. Always settle on a single scoring method before the first deal.
Winning the Game
Kachuful is played over a fixed set of rounds determined by the deal pattern (down to one card and back up, or down to one card, depending on your chosen format). A running score sheet tracks each player's points round by round. After the last round is scored, the player with the greatest cumulative total is the winner. Because a single perfectly judged round, or a single disastrous over-bid, can swing the standings, the game often stays competitive right up to the final, low-card hands where prediction is hardest.
Strategy tips
- Count the trump suit. With a fixed rotation you always know which suit is trump before bidding, so track how many high trumps you and your opponents likely hold. A couple of top trumps almost guarantee tricks; a bare trump may or may not survive.
- Use the hook to your advantage and against you. Because the dealer cannot balance the bids, one round is always over- or under-bid. If the table is over-bid, tricks will be scarce and someone must fail. Aim to be the player whose count is safest, not the one fighting over the last contested trick.
- Bidding zero is powerful but risky. A zero bid scores well and is often achievable with all low cards and no trumps, but you must duck every trick. Watch out for being forced to win a trick late when opponents flush out your only safe low cards.
- Mind the small-card rounds. When only one, two, or three cards are dealt, prediction is mostly luck and position. Bid conservatively, respect the trump, and remember the dealer's hook can box you in on these tiny hands.
- Read the bids before you play. The total bid versus total tricks tells you whether tricks are oversubscribed (someone must under-deliver) or undersubscribed (extra tricks are floating). Adjust whether you push for tricks or actively dump them.
- Throw your losers early. If your plan needs you to lose certain tricks to hit your bid, get rid of dangerous high cards while you can still safely under-cut, rather than being stuck winning an unwanted trick at the end.
Variants
Scoring variant: 1 point per trick won plus a 10-point bonus for hitting your exact bid (softer than the all-or-nothing standard). · Quadratic scoring: hit your bid for 10 plus the square of the tricks bid; miss and lose the square of the difference. · Penalty scoring: gain 10 per trick on a successful bid, lose 10 times the trick difference when you miss. · Random trump variant (classic Oh Hell): turn up the top card of the remaining deck each round to choose trump instead of the fixed Kachuful rotation. · No-trump rounds: play the one-card hand, or every hand, with no trump suit at all. · Deal pattern variant: count hands down from the maximum to a single card only (no climb back up) for a shorter game. · Simultaneous bidding: all players reveal their bids at once using fingers rather than bidding clockwise in turn. · Zero-bid limit: with 5 or more players, no one may bid zero more than five rounds in a row. · Reduced zero reward: a successful zero bid scores only 5 points, or 5 plus the number of cards dealt that round.
Kachuful (Judgement) — frequently asked questions
How do you play Kachuful (Judgement)?
Deal a hand to each of 3 to 7 players from a 52-card deck, set the trump suit (rotating Spades, Diamonds, Clubs, Hearts), and have each player bid the exact number of tricks they expect to win. Play tricks clockwise following suit when you can; the highest trump or highest led-suit card wins each trick. Score points only if you win exactly your bid, then change the hand size, rotate the trump, and play the next round.
What are the basic rules of Kachuful (Judgement)?
Each round you bid exactly how many tricks you will take. You must follow the suit led if you have it; otherwise you can play any card, including a trump. The highest trump wins a trick, or the highest card of the led suit if no trump is played. You score only when your tricks won exactly equal your bid; being over or under scores zero. The dealer bids last and cannot make the total bids equal the total tricks (the hook rule).
How is Kachuful scored?
The most common method gives you 10 points plus the number of tricks you bid when you win exactly your bid (so a correct bid of 0 = 10 points, a correct 2 = 12 points), and 0 points if you miss by any amount. A popular alternative awards 1 point per trick won plus a 10-point bonus for an exact bid. Scores add up across all rounds and the highest total wins. Agree on one method before you start.
What happens if you bid wrong in Kachuful?
If you win more or fewer tricks than you bid, you score nothing for that round under the standard rules, even if you missed by a single trick. There is no partial credit in the all-or-nothing scoring, which is exactly what makes the game so tense. Some groups use a softer method that still pays 1 point per trick taken, but the signature Kachuful rule is hit your bid exactly or get zero.
Why is the game called Kachuful and how does the trump rotate?
The name is a Gujarati mnemonic for the trump rotation: Ka (Kari = Spades), Chu (Chukat = Diamonds), Fu (Falli = Clubs), L (Lal = Hearts), literally 'raw flower.' The trump suit cycles through that fixed order Spades, Diamonds, Clubs, Hearts as the rounds progress, so players always know the trump before they bid. Some variants instead turn up a random card to pick trump each round.
What is the dealer hook (screw) rule in Kachuful?
The dealer bids last and is forbidden from bidding a number that would make the total of all players' bids equal the exact number of tricks available that round. This forces every round to be either over-bid or under-bid, guaranteeing that at least one player cannot make their bid. It is the key rule that keeps the game competitive and ensures no round ends with everyone safely hitting their number.
How many players can play Kachuful?
Kachuful works with 3 to 7 players using a single 52-card deck, and it plays best with 4 to 6. Hand sizes are adjusted so the deck is not exhausted: typically up to 10 cards each for 3-5 players, 8 each for 6 players, and 7 each for 7 players in the largest round, with the number of cards changing every round.
