This is a web version of the reflex card game
The goal is to take cards on the screen in groups of 3, known as sets.
The standard deck contains 81 cards each one with 4 unique features: color, shape, opacity, and quantity. Here you can see some cards and their features.

| Quantity | 1 |
| Color | Blue |
| Shape | Triangle |
| Opacity | Solid |
| Feature | Value |

| Opacity | Translucent |

A set is a combination of 3 cards where each of the 4 features are either all the same or all different. For example, the three cards shown above form a set, because each feature is expressed in all the cards. You can also have sets where some features are different and others are the same.
In the example below, the three cards are identical in opacity, solid, and color, blue, while being different in quantity and shape.
However, a group of 3 cards needs to be correct in all four features to be a set. The three cards below do not form a set, due to their color. Two of the cards are yellow while the third is red, so the three colors are neither all the same, nor all different.
When the game starts 9 cards are dealt from the deck. When a player takes a set, it is replaced on screen by 3 new cards from the deck. The game ends when the deck is empty and no more sets are available.
Sometimes, there will not be any sets among the 12 cards on screen. In these cases, the game will automatically deal out 3 extra cards until a set can be taken.
