Aces Up, also called The Idiot, is a simple but addictive solitaire whose name refers to the state of mind you reach, as it's not solved very often.
Four cards are placed on the table. If there are multiple cards in the same suit you remove the lower values, by dragging them onto the higher valued card.
After this you deal four new cards (or 1-3 to patch empty stacks) and repeat the previous procedure, now with the top cards in each stack.
If a stack is empty you can move any card (that is on the top in another stack) to the empty space.
You have won when all 52 cards have been dealt and you only have the four aces left!
