MSO FreeCell Arena
The classic card game, reimagined for fair competition.
Smart Auto-Moves
Cards automatically move to foundations when safe. Focus on strategy, not busy work.
Proven Hints
Stuck? Every hint is the first move of a winning line your game proves on the spot — not a guess, and not someone else's answer. If a deal has genuinely gone unwinnable, it tells you, and offers to rewind you to the last position that wasn't. Free and unlimited.
Unlimited Undo
Experiment freely. Undo any number of moves to try different strategies.
Keyboard Shortcuts
Power users can play entirely with keyboard. Z to undo, H for hints, number keys for columns.
4 Difficulty Levels
Easy through Extreme — and every one of them playable in Casual or Hardcore. Each combination tracks its own records.
Hardcore: One Life
No hints, no undo, and no second chances. The moment the deal becomes unwinnable, the game is over — and it counts. Hardcore deals are drawn from the proven-solvable pool, so a loss is almost always on you, not the shuffle — and the rare uncharted deal that isn't solvable is how the game's rarest badge gets earned.
Play in the Afterlife
Die in Hardcore and the Afterlife hands you the board back at the move before your fatal one. Play on under casual rules — undo, hints, a restart that returns to that moment — with no clock and nothing counting. Learn what went wrong, then try again for real.
Same Seeds for All
Everyone plays the same deals. Compare your moves, time, and efficiency head-to-head.
