How to Play

Players are presented with a board of number cards. The goal is to collect all cards by clicking on them one at a time. Each card adds its value to a running total displayed on the screen. The challenge is to keep this total between 0 and 21. If the total goes above 21 or below 0, the game ends. Players must think ahead about which card to pick next, as each choice affects future possibilities. The game ends when all cards are collected successfully or the total goes out of bounds. Players can restart at any time to try a different strategy. Controls are simple and responsive, whether using a touch screen or a mouse.

Tips for Success

Plan your moves in advance to avoid exceeding 21 or going below 0. Start by collecting high-value cards early if your total is low, or save them for later if you have room. Practice regularly to improve your ability to sequence cards efficiently. Take your time—there is no time limit, so you can think through each move carefully. Restarting is always an option if you want to try a different strategy.
