Warfare

A good game for practice.  Warfare involves 2 players or teams, which are split into 2 armies.  The winner is the first player or team to eliminate all their opponent's soldiers.  On the scoreboard, numbers 11, 14, 9, 13, 5, 20, 1, 18, 4 and 13 are written into the column for the top army.  Numbers 6, 10, 15, 2, 17, 3, 19, 7, 16 and 8 are written into the bottom army's column. 

Players take it in turns to try to hit the other army's numbers ie. kill their opponent's soldiers.  Once a number has been hit, it's crossed off and that solider is eliminated.  However, it is possible to eliminate your own soldiers by hitting your own numbers, so you need to take care.  This game can be adapted for varying skill levels by changing which are valid target areas.
