How to play

  1. Build columns downward in alternating colors. Only Kings can fill empty columns.
  2. Move Aces to the four foundations, then build upward in the same suit. Tap a playable top card to try its foundation.
  3. Double-tap empty table space to undo. Tap the stock on the right to draw three cards. Only the top waste card can move. Recycle the stock as often as you like, for free.
  4. Undo any move before settlement. Previously revealed cards remain remembered.
  5. End the round to collect 10% of your stake per foundation card. These are experimental practice payouts.

Foundation cards stay on their stacks; use Undo to reverse a placement. Auto solve searches from cards you have seen, plays one action at a time, and stops if its limited search finds no progress. You can stop it at any time. Hints, side bets, and real-money play are outside this prototype.
