In response to receiving a wager, a plurality of game elements are displayed as part of the wagering game. The plurality of game elements includes a play area, an enemy element that travels along an enemy path from an enemy entry location toward an enemy goal location, and a defense element that attacks the enemy element when the enemy element is within a defense attack range of the defense element. An enemy health value of the enemy element is reduced based on the defense element attacking the enemy element when the enemy element is within the defense attack range of the defense element. Reducing the enemy health value of the enemy element to zero destroys the enemy element. In response to the enemy element being destroyed, a second monetary amount is credited to the first credit account.
