Objective. Place every face card on its marked slot and remove every other card from the game.
The board starts empty. The deck is shuffled with its top card turned face up — that's the card you must place next.
Kings can only go on the four corner slots.
Queens can only go on the two middle slots of the top and bottom rows.
Jacks can only go on the two middle slots of the left and right columns.
Number cards (A–10) can go in any empty slot, marked or not.
Once the board is completely full, remove numbered cards in pairs whose ranks add up to 10 (like 8+2 or A+9), or a lone 10 by itself. Click one card, then the other — or click a 10 alone to clear it.
Keep clearing every combination you can find; once none remain, you resume placing cards from the deck into the freed slots.
You're stuck if you draw a face card with no open slot for it, or the board fills up with no pairs left to clear. Undo and try a different order.
