Castle Battle: Snake Shooter is a tower-defense game with a shooter element similar to brick-breaking games. As a castle guardian, the player's goal is to prevent giant snakes from destroying tower structures across 30 battles. They also attempt to earn a high number of coins and gemstones.
Each battle features a tower positioned near a short or long winding dirt road. The player doesn't manually fire weapons. Instead, they direct a dashed aiming line to auto-shoot projectiles in one or more directions. They also use power-up and upgrade cards over time to improve their capabilities.
When a giant snake slithers down a road, the player directs their aiming line at any colored segment of the creature's scales. Each direct hit reduces a floating number of associated points. In some battles, the player also shoots at giant chests to acquire much-needed power-ups. That said, that action can sometimes cost them a battle by distracting them too much from a long snake.
The game randomly displays power-up cards on the screen. The player can also use coin and gem winnings to perform upgrades on a map using the lower-left button. These tools can give them a huge advantage. For example, they can acquire an archer that shoots fire arrows, increase their attack speed or damage, and set up extra diagonal and front attacks with multiple projectiles.
Castle Battle: Snake Shooter gives the player options to upgrade the outward appearance and size of new tower icons over time as well. It offers many reward opportunities to cover upgrades. The player can claim daily, season pass, spin wheel and weekly rewards with and without ad views.
