Remove the JOKERS from your tile set.
Shuffle your tiles face down, then arrange them face up into a 7-row tall pyramid with one tile at the top, followed by a row of two tiles, followed by a row of three tiles, and so on until you've reached the final row of 7 tiles. It should look like a pyramid of 28 face-up tiles.
Arrange the remaining 24 tiles face down into a row at the top or bottom of your tableau, these will be used as your stock and waste piles.
Matching and remove pairs of tiles that add to 13. Kings can be removed on their own, Aces match with Queens, Twos match with Jacks, and so on. As you match pairs, you expose more tiles of the pyramid until you win by completely clearing the tableau.
When you filp a tile from the stock pile and it doesn't match to any exposed tiles in the pyramid, move it to the waste pile and flip another tile from the stock pile. You're allowed to match tiles from the stock pile with the waste pile. If the faceup waste and stock pile tiles can't be matched with each other or any exposed tiles, flip the face up waste tile to the face down position, slide the faceup stock tile to the waste pile, then flip the next tile in the stock pile row. You'll only ever have up to two tiles face up that aren't in the pyramid, one in the waste pile and one in the stock pile. If your stock pile flip can be matched to a tile in the pyramid, you can play it without moving the face up waste tile and flip the next tile in the stock pile.
Once all the unpaired tiles from the stock pile have been moved to the waste pile, "recycle" the waste pile back to the stock pile and be sure not to distrub the order of the tiles.
Decide how many recycles you'll allow. Some games allow 1 recycle, some allow 3, and some challenge players to clear the tableau without any recycles at all.
