For most variations, the basic 3-down-1-up battle pattern becomes 2-down-2-up. For

advanced games, however, the battle pattern is different: in case of a tie, the cards are

placed in a center pile. The next hand is played normally, with no cards turned down, and

the winner of that skirmish takes the center pile as well.

Addition War— Players turn up two cards for each skirmish. The highest sum wins.

Advanced Addition War— Turn up three (or four) cards for each skirmish and add them

together.

Subtraction War— Players turn up two cards and subtract the smaller number from the

larger. This time, the greatest difference wins the skirmish.

Product War— Turn up two cards and multiply.

Advanced Product War— Turn up three (or four) cards and multiply.

Fraction War— Players turn up two cards and make a fraction, using the smaller card as the

numerator. Greatest fraction wins the skirmish.

Improper Fraction War— Turn up two cards and make a fraction, using the larger card as the

numerator. Greatest fraction wins.

Integer Addition War— Black cards are positive numbers; red cards are negative. The

greatest sum wins. Remember that -2 is greater than -7.

Integer Product War— Black cards are positive numbers; red cards are negative. The

greatest product wins. Remember that two negative numbers make a positive product.

Wild War— Players turn up three cards and may do whatever math manipulation they wish

with the numbers. The greatest answer wins the skirmish.

Advanced Wild War— Black cards are positive numbers; red cards are negative numbers.

Players turn up four cards (or five) and may do whatever math manipulation they wish with

the numbers. The greatest answer wins the skirmish.

Reverse Wild War— Players turn up three cards (or four, or five) and may do whatever math

manipulation they wish with the numbers. The answer with the lowest absolute value (closest

to zero) wins the skirmish.
