Rummy 500 Strategy

1. Judge a pile take by its cost, not just its prize

The spread discard pile is the most exciting thing about Rummy 500 and the easiest place to lose a game. When the card you need is six deep, taking it means six extra cards in your hand — and every one of them counts against you if your opponent goes out before you shed it. Before you dig, add it up: what will you meld right now (the card you take must go down, plus anything else the stack completes), and what will you be left holding? A take that completes a 30-point set and leaves you with two junk Sevens is excellent. A take that completes a 9-point run and leaves you with a King, a Queen and an Ace is a trap.

Two things tip the balance. Early in the hand, with a deep stock, the extra cards have time to find melds and the dig is cheaper. Late, with the stock thin and the opponent's hand short, every unmelded card is a likely loss. And look at what the stack gives your opponent: taking a big stack also removes those cards from their reach, which matters when you can see they have been collecting a rank that is sitting in the pile.

2. Meld now or hold? Let the stock decide

In Gin Rummy you hide your melds; in Rummy 500 there is no reason to hide them, and opinions differ only on how long to hold one. The case for melding at once: a meld in your hand is worth nothing until it is on the table, and it costs its full value if your opponent goes out first — being caught with a three-card meld costs you three cards, while a lay-off on it scores them one. The case for waiting a turn or two: cards in your hand keep your options open. Three of a rank can become four (30 into 40 points) with no lay-off for the opponent, a pair or a near-run in hand is what lets you dig for a matching card in the pile, and every meld you put down gives the other player a place to shed their odd cards.

The stock settles it. While the stock is deep and your opponent holds a long hand, holding a meld for a turn or two is a defensible choice. Once the stock is short, or your opponent's hand is down to a few cards, waiting gains nothing and risks everything — meld it all and cut your losses. If in doubt, meld: the cost of being caught is certain, the gain from waiting is not.

3. Lay off freely — on their melds especially

A lay-off is a card that scores for you and can no longer be counted against you, and it costs nothing. Whenever a card in your hand fits a meld on the table, laying it off is almost always right: the reasons to hold it are that it belongs to a meld you are about to make yourself and would score more there (an Ace that could top a Q-K run for 15 rather than sit under a 2-3 run for 1, say), or that it is the card that lets you dig for something better in the pile. Laying off on your opponent's melds is doubly good — the points go to you, and the card is one they can no longer collect. Keep an eye on the table every turn; a card that fitted nothing when you drew it may fit something the computer melded a moment ago.

4. Discard safely: cards that fit the table are gifts

Your discard is an offer. Any card that can be laid off on a meld already on the table can be taken by your opponent at no cost — they pick it up, lay it off, score it, and discard as usual. Avoid throwing a card that fits a table meld unless you are going out with it or it is your only choice. Beyond that, the usual rummy sense applies: shed high unconnected cards first (a lone King costs 10 if you are caught with it, a lone Three costs 3), keep pairs and near-runs while the stock is deep enough to complete them, and prefer discarding a card whose partners you have already seen go by. A rank your opponent just dug for is never safe.

Remember that the pile itself is a hand anyone can dig into. Because the deepest card you take may be melded with the cards you pick up along the way, two Sevens already in the pile make a third Seven a gift: your opponent can dig to the lower one and meld all three without holding a single Seven. Before you discard, look at what your card would combine with in the pile, not just on the table.

5. Read what they are collecting

Because the pile is spread, every take is public information: the card your opponent reached for tells you the rank or suit they are building, and the cards above it tell you what they now hold. Keep a rough note. When you have a choice of discards, throw away from those ranks and suits. When you are choosing between two melds to put down, put down the one their known cards could lay off on last. And when they dig deep, count how many cards they now hold — a 20-card hand is a long way from going out, which is your cue to hold melds a turn longer or to dig yourself.

The Hard computer opponent does exactly this: it remembers the ranks and suits you have taken from the pile and avoids feeding them, keeps its pairs and near-runs rather than discarding them while the stock is deep, dumps unconnected high cards early and races to go out when your hand is short. It melds everything it can every turn, so expect it to be stingy with the cards you want rather than with its melds.

6. Race to go out when the hand turns

Going out is worth more than any single meld: your own deductions go to zero and your opponent pays for everything in their hand. Watch the card counts in the seat badges. When you are down to three or four cards and they hold ten, stop collecting and start shedding — meld anything, lay off anything, discard the highest card that fits nothing. When the positions are reversed and they are close to going out, the priority flips: empty your hand of points as fast as possible, even at the cost of melding a set of three that you hoped to make four, because being caught with 40 points is worse than missing out on 10. Remember too that you do not need a final discard — if your last card can be melded or laid off, the hand ends at once.

7. Respect the Aces

An Ace is 15 points — the most valuable card and the most expensive to be caught with. A set of Aces (45) is the best meld in the game; an Ace at the top of a Q-K-A run is a 15-point card; an Ace at the bottom of an A-2-3 run is worth 1, which is sometimes still right if it is the only way to shed it. Do not hold a lone Ace hoping for partners while the opponent's hand shrinks: it is the first card to lay off if a Q-K run, a set of Aces or a 2-3 run will take it, and the first to discard if not — on CardCouch an Ace in the pile is an Ace your opponent must meld at once to take, which is harder than it sounds. (Check the pile first: if two Aces already sit in it, yours completes a set for anyone.)

8. Play the end of the stock

When the stock is nearly gone, the hand can end without anybody going out: the next player to face an empty stock must take from the pile or the hand is over. Count the cards. If you are ahead on the table and holding little, you want the stock to run out — meld everything, discard your highest card, and let the hand end. If you are behind, you need the hand to continue: keep a pile take in reserve (a card you know you can meld) so that when the stock is empty you can still take and keep the hand alive. On CardCouch the choice is yours whenever a legal take exists: with the stock empty an “End hand” button replaces it, so end the hand when the score favours you and take when it does not. If no card in the pile can be melded, the hand ends by itself.

9. Play the score, not just the hand

A game is to 500 and both players score every hand, so a lead of a hundred or more is usually a real cushion and the same deficit needs big hands to close. When you are well ahead, play safe: meld early, dig shallow, discard high, and treat every hand as damage limitation. When you are far behind, take risks: dig deep for the stacks that complete two melds at once, hold a set of three for the fourth, and aim to go out with a table full of points. The score sheet in the sidebar shows each hand's net, which makes it easy to see whether you are winning on melds or losing on what you are caught holding — and to fix the right one.
