How to Play
Click on one of the holders to place a card in it. Cards have the following price values:
Cards with a number: the price is the number on the card.
Picture cards: the price of all is 10.
Ace: 1 or 11. Usually counts as 11, but if this counts the sum of the points in your hand as more than 21, the ace counts as 1.
Collecting 21, 5 cards in the holder or putting a joker in it will reset the stack and you will be awarded points.
Tips
When starting out, focus on learning the point values of face cards and aces—remember that aces are flexible and can save you from busting! Always keep an eye on your current stack sum before placing a new card, and don't be afraid to use jokers if you're stuck. Try to plan a few moves ahead to avoid getting cornered with high-value cards.
Advanced Strategies
Once you're comfortable, experiment with deliberately collecting five cards in a holder instead of chasing 21 every time—sometimes this is a safer path to points. Save your jokers for when your stack is dangerously close to busting, as they act as a reset lifeline. Pay attention to the flow of cards and try to maintain multiple holders with moderate scores, giving you more flexible placement options as the game progresses.

Collecting exactly 21 points, gathering 5 cards in a holder, or placing a joker will reset the stack and award you points. Be careful not to go over 21!
Keep track of your running total before each placement to avoid busting. Use aces wisely since they offer flexibility, and don't forget that collecting 5 cards in a holder is an alternative way to score. Save jokers for tricky situations where you're close to busting.
