Can I lay off cards on the knocker's melds?

No. This version scores the hands as they are.

What if the stock runs out?

When only two cards are left the hand is a draw and nobody scores.

No. Ace is low only, so A-2-3 is a run but Q-K-A is not.

Build sets and runs, knock with 10 or fewer deadwood points and beat the computer. Gin and undercuts included.

A real run of the game, recorded with captions and no sound.

You each hold ten cards. On your turn, draw the top of the stock or take the top discard, then discard one card.
Arrange cards into melds: sets of three or four of a kind, or runs of three or more in one suit (ace low). The cards left over are deadwood (ace 1, face cards 10, others their number).
When your deadwood is 10 or less, pick a card and press Knock. The hands are shown and the lower deadwood scores the difference.
Going gin (no deadwood) scores a 20 point bonus. If the other player has equal or less deadwood than the knocker, they undercut and score the difference plus 10.

Controls: mouse or touch. Made by CalcoTools.

Framed cards on screen are already in melds, so the unframed ones are the ones to think about discarding.
Take the discard only when it completes or extends a meld.
Throw away high cards you cannot match: they cost the most if the computer knocks.
Do not knock too early with exactly 10: a computer hand that is lower will undercut you.
