The short answer (Modern American Canasta)
In Modern American Canasta, all four threes work exactly the same way regardless of color. Red or black does not matter. What matters is how many threes your team is holding at the end of the round and whether you melded.
The scoring progression
| Threes held by your team | If you melded | If you did not meld |
|---|---|---|
| 1 three | +100 | -100 |
| 2 threes | +300 | -300 |
| 3 threes | +500 | -500 |
| 4 threes (one team holds them all) | +1,000 | -1,000 |
So three threes (any combination of colors) is worth either +500 or -500. Four threes is +1,000 or -1,000.
The most common mistake players make
You will see plenty of online sources say that red threes and black threes score differently, or that the bonus values are 100, 200, 300, 800. That is the Classic Canasta rule, written for the original 1950s game.
If you are playing the version most American Canasta players play today (Modern American Canasta), the threes work as the table above shows. Color does not change the score.
The "must have a canasta to score" rule
If you have no canastas at the end of the round, Threes are scored as negative points. If you have one canasta, Threes are scored as no points. If you have 2+ canastas, Threes are scored as positive points.
How threes are played
Threes are not played the way other cards are. As soon as you draw or are dealt a three, you place it face-up on the table in front of you and immediately draw a replacement card from the stock. They are scored at the end of the round.
What about Classic Canasta?
If you are playing the original 1950s Classic Canasta rules, red threes alone count as bonus cards (typically 100, 200, 300, 800), and black threes act only as a discard-pile freeze and a final-play meld. The two games share most mechanics but diverge on this exact point. Make sure everyone at the table is playing the same version before the round starts.
