OBJECTIVE
The object of the game is to form palindromes of length 4 or greater. A palindrome is a sequence of numbers that is the same if read forwards or backwards (e.g., 1221 or 12321).
 
HOW TO PLAY
When it's a player's turn, indicated by the light, the player clicks and drags one of the two pieces from their queue to one of the grid columns. Releasing the mouse button over a column drops the piece in that column. If the player forms a palindrome, the player scores and those pieces are removed from the board. Then it is the other player's turn.
 
2-Player: Play continues until the grid is full. Whoever has the highest score at the end of the game wins.
 
1-Player: Beat the computer to the next level score. If you do, you move on. Part of your points will carry over based on your winning score. New levels introduce new number and color pieces. If the board fills up, the game is over.
 
SCORING
Longer palindromes are worth more points. You can improve your score by forming more than one palindrome on your turn. A bonus is given if the color sequence forms a palindrome as well (e.g. blue-green-red-green-blue).
