Gin Rummy 2-player
Build sets and runs, cut deadwood, then knock or go Gin. Every deal and computer decision stays in your browser.
Review Spots
When your draw, discard or knock differs from the disclosed local reference, the exact visible decision state is saved here. Clear a spot only by matching the same reference on a clean first try.

Advanced analytics & fixed benchmark
Decision Review & Repeatability Lab
Turn each local hand into inspectable evidence. Review draw, discard and knock decisions using exact deadwood math plus clearly disclosed local rubrics—never hidden-hand guesses or a fake perfect-play engine.
Same fixed benchmark, five clean runs
Clean 5 is your own repeatability only. It is not a rank, percentile, IQ score or population norm.
Replay your decision timeline
No decision timeline yet. Play a hand to build a local replay.
Replay stores your own visible-hand decisions and final hand result locally. It does not inspect the opponent’s hidden hand while play is active.

Export or restore Gin Rummy evidence
Backup contains local Gin Rummy stats and V0.200 lab evidence only. No account or server upload is required.
Make the cards easier to read
The four-color option changes suit colors only; rules and decisions are unchanged.
Sets and runs lower deadwood
Each player receives 10 cards. A set is three or four cards of one rank. A run is three or more consecutive cards in one suit. Aces are low only.
Knock at 10 deadwood or less
After your discard, you may knock with no more than 10 deadwood points. Zero deadwood is Gin and earns a 25-point bonus.
The defender can reduce deadwood
After a normal knock, unmatched cards may lay off onto the knocker’s melds. Layoff is not allowed against Gin.
Knocking too early can backfire
If the defender finishes with deadwood no higher than the knocker, the defender scores the difference plus a 25-point undercut bonus.
The last two cards stop the hand
If the stock reaches two cards and a player needs to draw from it, the hand ends without a score and the next deal begins.
Cards are strategy, not wagering
This is a free browser strategy game with no wagering. There are no bets, chips, prizes, stakes, purchases or paid random mechanics.
