Knock early instead of chasing gin
Gin pays more, but the hands where you hold on for it are the hands you lose. Once your deadwood is low enough to knock, the maths usually favours taking it: you end the hand on your terms, you stop your opponent improving, and you take the points that are on the table rather than the ones you hoped for. Chasing gin also means holding cards your opponent may need, which is exactly how a close hand turns into an undercut against you.
Discard the high unmatched cards first
Deadwood is scored by card value, so an unmatched king costs you ten points and an unmatched three costs three. Clearing the high cards early keeps your deadwood low enough to knock at short notice, which is what makes the first tip possible. The exception is a high card that is genuinely one card from a meld with a card you have seen nobody take, and even then it is worth asking whether that meld is likely to arrive before your opponent knocks.

Watch what your opponent picks up
Every card taken from the discard pile is information, and in a game this fast most players give away more than they realise. If an opponent takes a seven, holding sevens and the cards either side of it is dangerous. The same goes in reverse: think before discarding a card adjacent in rank or suit to one they just picked up. Playing against the discard pile rather than only your own hand is the single biggest skill gap in this game.
Pick the table your balance can survive
The Coin economy here tightens as you climb: players consistently report that payouts at higher-stakes tables do not keep pace with the buy-ins, so a run of bad hands at a level above your balance is how accounts end up empty. The workable rule is to play where a losing streak of several hands still leaves you able to sit down again. Move up after you have doubled your balance, not after one good hand.
Play inside the contest windows
Contests run automatically every few hours and rank players on results within the window, paying the top finishers. Since you are entered simply by playing, the free upgrade to your routine is to time your session to overlap with one. Same hands, same stakes, with a prize attached. Combine that with the four-hour bonus collection just before you start and you are playing on free Coins for a prize.
Let the missions choose your session
Daily challenges and Stars Rush missions reset every day and pay for objectives you can hit during ordinary play, but only if you know what they are. Reading them first sometimes changes which table you sit at or how long you stay, and that small adjustment is worth more than playing well at random. Anything left unfinished at the reset is worth nothing.
Keep the Coin routine going
Strategy keeps you at the table; the free sources keep you in the game. The four-hour bonus, the login streak, level-ups, album sets, the free Game Pass track and the referral programme together cover a normal player's losses. The Coin links on this page sit on top of that, collected newest first so you can see everything still claimable in one look.
