About Solitaire AI

Solitaire AI is classic Klondike Solitaire with a built-in AI assistant. Stuck? Ask for a hint and the AI highlights a good next move. Undo mistakes, tap a card to send it to the best spot, and auto-finish when the game is solved.

How to play

  1. Build the four foundations up by suit from Ace to King.
  2. On the tableau, build down in alternating colours (red on black).
  3. Only a King (or a run starting with a King) can fill an empty column.
  4. Tap the stock to turn over a card; tap again to recycle when it runs out.

Strategy & practical tips

  1. Prefer moves that reveal a face-down card or free a useful column. Moving visible sequences back and forth without opening anything can waste time.
  2. Before clearing a column, identify the King or King-led sequence that can use it. Other ranks cannot occupy an empty column.
  3. Use hints to find a legal next action, and Undo to compare alternatives. The assistant follows priorities; it does not prove a winning solution.

A common mistake

Assuming a suggested move guarantees a win. Shuffled deals are not guaranteed solvable, and the hint system does not search every future position.
