COMBO!
To create a Combo deck, use index cards to make cards #1-24 in the quantities listed below:
1-9 (x3)
10-19 (x2)
20-24 (X1)
Basic rules:
5 cards each player
Flip top card
Get to that number using a combo of two or more of the cards in your hand. If it is a tie, the person who uses the most cards wins.
Remember to use Order of Operations: PEMDAS or GEMS (grouping, exponents, Mult/Div, Sub/add) left to right.
