Wha Best fun way to teach programming through a computer game?

Try and use funny names for each part in the program depending on which age group they are. Also make jokes in between and smile a lot. Don't keep talking on and on because students get bored by that believe me i'm a student myself. Playfully tease often and help every student to their skill level, because rushing every person to the same level is not very fun if they don't get it. Hope this helps!! God bless you!!
