4. Blow Gun Defense Game Guidelines
Preparation
Each player sets the game platform on a level playing surface.
Rules for Play
The building blocks are to be divided evenly between each player.
All players are allowed one minute to set up a tower.
At the end of the minute, players use their blow guns to try to destroy the other player’s tower.
Different Game Modes
Total Destruction: Players win by knocking all of the opponent’s blocks outside his game surface.
Strategic Attack: One block is designated as the critical block, and players win by knocking the opponent’s critical block outside his game surface.
Get creative, and come up with unique and personalized ways to play!
