Collect 21!

About Collect 21!

Collect 21! is an endless card game that blends classic blackjack mechanics with addictive strategy. The goal is straightforward: collect cards across four stacks and hit exactly 21 points — without going over. Push past that limit and you pay the price. Several scenes show four vertical columns sitting above rectangular boxes that display numeric digits, and the background shifts between a dark blue gradient and a green and orange gradient across different views of the game.

How to Play Collect 21!

Each turn, click one of the four stacks to place a card onto it. Every card carries a point value, and managing those values across all four stacks is the core challenge.

Card Values

• Numbered cards: worth the number printed on the card
• Picture cards: each worth 10 points
• Ace: counts as 11, but drops to 1 if counting it as 11 would push the stack's total above 21

Stack Resets and Consequences

• Reaching exactly 21 in a stack resets it and awards points
• Filling a stack with 5 cards resets it and awards points
• Placing a joker in a stack resets it and awards points
• Exceeding 21 in a stack costs a life and resets that stack

Controls

• Click on a stack: place the current card into that stack
