Variations:

• Everyone starts with their hands on their knees or behind their back. 
• Keep things interesting when there is only a couple of cards remaining by saying words not in the remaining cards, but tell the students you are going to do this, damasu.
• Use various objects to slap the cards instead of the conventional hand -- fly swatters, piko-piko hammers, etc.
• Uno Scramble:  Submitted by: Kirsten Phillips
• This game is based on the children's game; Steal the Bacon.  In the class, divide the students into 2 teams and have them sit in a straight line facing each other.  The first student in each group will play against each other and the second student in line will play next. 
• Put the Uno cards or playing cards between both teams.  Remember to put the cards randomly in between both teams.
• Teacher will call out a number, the first students in line will rush to pick up the card with the correct number and give it to the teacher.  The first student to bring the number card to the teacher wins a point.
• It is recommended to encourage students to say the number they are holding when they are giving it to the teacher.
• For higher level, teachers can make the games more difficult by calling out the number + color of the card.
