Each card has four values that mean the value of each side.
Flip rival cards by placing one with a higher value next to it.
The one with the most cards at the end of the game wins.
Game Rules
The rules apply beyond the normal functioning of the cards, only at certain levels.
Open: The cards to be used are visible from the beginning.
Equal: If a card is placed with two or more edges whose values equal those of adjacent cards (own or opponent's), the opponent's adjacent cards will be turned over.
Sum: If a card is placed with two or more edges whose sums with adjacent cards' values (own or opponent's) are equal, the opponent's adjacent cards will be turned over.
Chain: If Sum or Equal flips two or more cards, those cards can flip adjacent opponent cards if their values are higher, but only once (no further chaining).
