Interlock

You complete Interlock when every card reaches the required foundation under this profile's rank, suit, direction, and access constraints. The engine evaluates the full position rather than relying on a visual shortcut or an unsupported solvability claim.

How to play

You complete Interlock when every card reaches the required foundation under this profile's rank, suit, direction, and access constraints. The engine evaluates the full position rather than relying on a visual shortcut or an unsupported solvability claim.

  • Interlock opens from a versioned seeded position built for A 30-card 11/10/9 overlap graph permits a dropdown move when the sole covering sequence legally continues the newly exposed card; bottom gaps require Kings. Its game ID, rules profile, and deal identity are stored together so restart recreates the same opening without a server request.
  • Every Interlock action is checked against the current board, available material, and this defining restriction: A 30-card 11/10/9 overlap graph permits a dropdown move when the sole covering sequence legally continues the newly exposed card; bottom gaps require Kings. Invalid, stale, or post-terminal actions leave the position unchanged.

Strategy tips

  • A practical Interlock plan is to preserve several legal continuations around A 30-card 11/10/9 overlap graph permits a dropdown move when the sole covering sequence legally continues the newly exposed card; bottom gaps require Kings. Use the deterministic hint to inspect one legal action, then compare how it affects the documented objective before committing.
  • A common Interlock error is to ignore the boundary rule that A 30-card 11/10/9 overlap graph permits a dropdown move when the sole covering sequence legally continues the newly exposed card; bottom gaps require Kings. Undo is useful for studying that decision, while restart deliberately preserves the original seeded position.
  • Near the end of Interlock, recount the remaining obligations needed until every card reaches the required foundation under this profile's rank, suit, direction, and access constraints. Check the boundary rule after every final placement or transfer because terminal status is enforced immediately.

Rules, scoring, and strategy

Interlock uses the independently implemented Interlock PySolFC 3.6.1 rules profile v1 profile (R401). Interlock is a complete deterministic browser game whose distinct rules centre on A 30-card 11/10/9 overlap graph permits a dropdown move when the sole covering sequence legally continues the newly exposed card; bottom gaps require Kings.

Questions players ask

What makes Interlock a separate game?

Interlock has its own runtime and save identity because its rules require A 30-card 11/10/9 overlap graph permits a dropdown move when the sole covering sequence legally continues the newly exposed card; bottom gaps require Kings.

Which Interlock edge rule matters most?

A 30-card 11/10/9 overlap graph permits a dropdown move when the sole covering sequence legally continues the newly exposed card; bottom gaps require Kings.

Can a Interlock position be reproduced?

Interlock stores its game ID, rules version, and seeded deal identity. Those values recreate the same opening locally without promising that the position is forced or winnable.
