Thanks for the feedback! I changed the rules description, so hopefully it's clearer now, but please let me know if it still doesn't make sense:
The goal is to play more cards than the computer. Cards come in 4 colors and are numbered 1 through 9.
Rules for playing cards:
- A number 1 of any color can be played on any blank spot
- When a spot has a card on it, only a card of the same color and 1 number higher can be played on it
- For example, red 1 can only have red 2 played on it, blue 7 can only have blue 8 played on it
Press space to cycle to a new card if you can't play your current one. There are no turns, so play as fast as you can!
If the computer plays where you wanted to play, you have a second chance! If you click that spot quickly enough, your card will replace the computer's.
