Endlock

Build a branching chain by alternating card colors and adjacent ranks. Outsmart the computer and empty your seven-card hand first.

Overview
Endlock is an original card game built around constraint-based placement — a puzzle-like battle of tactics against the computer. Starting from a Joker anchor in the centre, both players build a branching chain outward, and the empty slots around the layout open and close as cards are ‘locked’ into place. The first player to empty their seven-card hand wins, so every placement is about keeping your own options open while closing off your opponent’s.
About the game

Endlock is an original two-player card game played on an expanding layout. Every card you place creates new possible branches while other gaps close as the board grows.

The browser edition offers Easy and Hard matches against the computer.

How to play
  1. Select a card from your hand.
  2. Choose a highlighted open position beside one placed card.
  3. Match a rank exactly one step higher or lower and alternate red with black.
  4. If no card can be played, draw until a playable card appears.
  5. Place every card in your hand before the computer.
Easy and Hard modes

Easy: a Joker begins in the center, so any rank may start each initial branch. The computer chooses from its available moves more casually.

Hard: the card after the opening deal becomes the center anchor, and the computer evaluates its available moves more carefully.

Placement rules
  • Red cards connect only to black cards, and black only to red.
  • Ranks must differ by one; Ace connects to Two and King.
  • A Joker may be placed in any open position and accepts any rank beside it.
  • A gap is open only while it touches exactly one placed card; touching two cards closes it.
Drawing and winning

When your hand has no legal move, use the draw pile. Unplayable draws move to the discard pile until a playable card is found. If the stock empties, the discard pile is shuffled and reused.

The first player to empty their hand wins immediately.

Tips and strategy
  • Preserve cards that can extend more than one branch.
  • Use Jokers to escape awkward hands or open flexible routes.
  • Watch which ranks and colors the computer is placing.
  • In Hard mode, avoid creating easy continuations for your opponent.
Frequently asked questions
Is Endlock free to play? Yes — free in your browser, no sign-up. How do I place a card? Play one rank above or below the end card and alternate red and black; Ace connects to both 2 and King. What makes a slot playable? A slot works only if it touches exactly one placed card; if it touches two, it closes. What do Jokers do? A Joker in hand is wild and can be played on any open slot.
