Treasure Trove Solitaire

Treasure Trove is the alternate name for Osmosis Solitaire. Four reserve piles of 13 cards each hide your "treasure" — the cards needed for foundations. The osmosis rule (each row needs the rank present in the row above) creates a cascading unlock system. Dig through the reserve to find the cards that build your first foundation row, which in turn unlocks the treasures for rows below.

What’s Different from Osmosis Solitaire

The same game as Osmosis under its alternate name — identical cascading foundation rules, 4 reserve piles, and three-card stock draws with unlimited redeals.

Treasure Trove Tips

Think of the first foundation row as the "master key" that unlocks everything. Play from reserve piles strategically — expose cards needed for Row 1 first. The stock pile supplements your options, but the real game is in reserve management. Check all four reserve pile tops before drawing from stock.
