Clean vs. Dirty Canasta
A canasta is a meld of seven cards of the same rank — and the single biggest scoring decision in Hand and Foot is whether your canastas come out clean or dirty. The difference is worth 200 points each, and it shapes how you use your wild cards all game long.
The one-sentence difference
A clean canasta has no wild cards — seven natural cards of the same rank. A dirty canasta includes at least one wild card (a joker or a 2) standing in for a natural. That's it. Same length, same rank requirement; the only question is whether wilds helped build it.
Clean canastas are sometimes called "red books" and dirty ones "black books," but the rules are the same wherever you play.
The scoring gap that drives everything
Canasta
Bonus
Clean (no wilds)
+500
Dirty (with wilds)
+300
That's a 200-point swing for the same seven cards. Over a four-round game, choosing clean over dirty a few times can decide the match. The card face values inside the meld score the same either way — the gap is entirely in the bonus.
The rules on wild cards
Two limits apply to every meld, clean or dirty:
At least two naturals.
A meld can never be all wilds — any meld that holds a wild must contain at least two natural cards of its rank.
Wilds stay strictly fewer than naturals.
In any single meld, the wild cards must be strictly fewer than the natural ones — an even split is rejected. So a seven-card dirty canasta can hold at most three wilds (four naturals, three wilds).
Jokers are worth 50 points and 2s are worth 20, so wilds also pad your face-value total — but only if they're on the table when the round is scored.
When to go clean vs. dirty
The +200 gap makes clean canastas the goal, but dirty ones earn their place. A few rules of thumb:
Go clean when you can.
If you're collecting naturals of a rank quickly, hold off on dropping wilds into that meld and let it close clean. The extra 200 is almost always worth a little patience.
Go dirty to close, or to protect.
Use a wild to complete a canasta when you need that book on the table to be allowed to go out (teams need four clean and three dirty; solo needs one clean and one dirty), or when finishing a meld now denies an opponent the chance to take the pile. A dirty canasta in hand beats a clean one that never happens.
Save wilds for where they pay.
Wilds are flexible and valuable — don't sprinkle them across many melds. Concentrate them where they finish a book or unlock your go-out, not where a natural would have arrived anyway.
Remember you need both — and enough of each.
Going out requires both clean and dirty canastas on your side: four clean and three dirty in team play, or one clean and one dirty solo. Dirty books aren't optional — plan for them rather than being forced into them at the end.

Frequently Asked Questions
What's the difference between a clean and dirty canasta?
A clean canasta is seven same-rank cards with no wild cards (+500 bonus). A dirty canasta is seven same-rank cards that include at least one wild (+300 bonus).
How much is a clean canasta worth?
A +500 bonus, on top of the face value of all seven cards in the meld.
How much is a dirty canasta worth?
A +300 bonus, on top of the face value of the cards in the meld.
How many wild cards can a dirty canasta have?
Wilds must always be strictly fewer than the naturals in a meld — an even split is rejected — so a seven-card canasta can include at most three wild cards (four naturals, three wilds).
Do you need both a clean and a dirty canasta to go out?
Yes, and the counts scale by mode: teams need four clean and three dirty; solo needs one clean and one dirty. Those canastas must be on the table before a player empties both Hand and Foot.
Are wild cards worth points?
Yes — jokers are 50 points and 2s are 20 — but only if they're in a meld on the table when the round is scored. Left in your hand or foot, they count against you.
