What is 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.

How to play Stackitaire

Tap a stack to pick up the top card, then tap another stack to place it there.

You can only place a card onto another card of the same suit, or into an empty stack.

A stack is complete when it holds a full suit, sorted from bottom to top.

Clear all stacks to finish the level.

Boosters

Undo — Take back your last move if you played the wrong card.

Hint — Highlights the best next move when you're stuck.

Key — Unlocks a sealed stack, flipping hidden cards face-up so you can play them.
