Gargantua rewards long-horizon planning.

Core Gargantua tips

• Treat the two stock passes as a finite resource. Do not exhaust the first pass clearing obvious moves — save difficult buried cards for the second pass.
• In the early game, focus on uncovering face-down cards in the longer columns (7, 8, 9) before they become impossible to reach.
• Build tableau sequences that run across multiple columns so you can shift entire groups when a deeper card is needed.
• Do not rush all foundations at once — advance them in tandem so that duplicated cards (from the two decks) become useful rather than redundant.
• Keep at least one empty column as a staging area whenever possible. Empty columns are rare in a nine-column layout and extremely valuable.
• Only Kings and King-topped sequences can fill empty columns, so plan your King placement to unlock the most buried cards.
• When a card exists in duplicate, one copy can often be sacrificed to a foundation earlier, freeing the other copy to serve as a tableau anchor.

The two-pass rule changes everything

Unlike Klondike where multiple redeals let you recover from mistakes, Gargantua's two-pass limit means cards you cannot reach in the first pass must be reached in the second — or the game is lost. Plan each pass with a clear goal rather than just cycling through.

Common mistake

The most common mistake is advancing one or two foundations far ahead of the others. This locks up the duplicate cards you need for tableau sequences, stalling all further progress.
