Stackitaire

Stackitaire is an addictive solitaire card-sorting puzzle. Shuffle through stacks of mixed cards and sort them into complete suits — one suit per stack. Every level deals a new layout that gets trickier as locked cards, hidden decks, and tighter stacks are introduced. With hundreds of levels, daily bonuses, and handy boosters to rescue a tough hand, Stackitaire is the perfect blend of classic solitaire and satisfying puzzle play.

Tips:
Keep at least one stack empty as a holding spot — it gives you room to reorganize.
Think a few moves ahead before placing a card; getting blocked is how levels get tough.
Use Undo before spending a Hint.
