Nah, it's not really my own. It's a variation of a game that I saw on a television show - Survivor.

The Survivor competition involved two teams, taking between one and three flags out of 21 flags, to start - working out to the same solution. The major difference being that they played for a million dollar grand-prize and we're playing here for peanuts and giggles.

Oh well, lol.

Hey, thanks for the compliment and, by all means, have fun sharing it with the children. I'm glad that you enjoyed it.
