FreeCell move capacity

FreeCell Sequence Moves: Calculate Your Capacity

FreeCell moves a sequence by simulating legal single-card moves through open workspace. Empty free cells and cascades therefore control the longest group you can move.

01

Use the practical formula

Maximum length is (empty free cells + 1) × 2 to the power of empty cascades.

  • 2 free cells and 1 empty cascade: 6 cards
  • 0 free cells and 2 empty cascades: 4 cards
  • Do not count an empty destination as extra workspace
02

Validate the sequence first

Capacity does not make an invalid tail movable. Every card must descend by one and alternate red and black.

  • Expose the top card
  • Check every colour change
  • Check every rank step
03

Protect workspace

An empty cascade multiplies capacity. Fill one only when the move releases a low card, opens another cascade, or creates a stronger continuation.

  • Keep one free cell open
  • Avoid parking cards without an exit
  • Release Aces and low cards
