Shuffle the deck and deal 4 face-up piles to each player, with 1, 2, 3, and 4 cards in each pile
Place the remaining cards face down as each player’s Blitz pile
Turn the top card of each Blitz pile face up to start the game
Keep your own 4 piles in front of you and your Blitz pile to the side
Play cards from your face-up piles or Blitz pile onto the center piles in ascending order by color
Start each center pile with a 1, then continue with 2, 3, and so on up to 10
Only play a card if it matches the color of the center pile and is exactly one number higher
Move cards from your face-up piles by uncovering the next card underneath after playing one
Turn over the next card from your Blitz pile whenever the top card is played
Play as fast as possible; there are no turns
Only one card may be played at a time
If you cannot play, rearrange your face-up piles or wait for a new play
When your Blitz pile is empty, shout that you are out
The round ends when one player empties their Blitz pile
Count points based on cards left in your Blitz pile and cards played to the center
Keep score over multiple rounds until someone reaches the agreed winning total
