みならい王子のみならい防衛

The Rookie Prince’s Defense Trials

In this tower defense game, you play as a young prince trying to save castles left on the brink of collapse by monster attacks. Fight off the monsters while repairing your defenses.

By day, work within a limited budget to repair walls and cannons, strengthen your soldiers, and prepare for the night’s assault. Each area has a monster boss. Defeat it and keep the castle standing!

Each round takes about 5–10 minutes, making it easy to play whenever you have a little spare time.

There are 16 castles to defend, each with its own terrain. Defense missions challenge you to find more efficient strategies. Every successful defense helps the prince grow and unlocks items he could not use before.

By day: Repair and prepare

- Upgrade your castle with a focus on attack or defense to suit the terrain and the monsters you face.

- Repair walls and cannons. As your castle levels up, you can improve your cannons’ attack power, defense, fire rate, and range.

- Recruit soldiers at the barracks. As your castle levels up, they can change jobs to swordsmen, archers, knights, mounted knights, snipers, or mages.

- Build houses to support the castle’s economy.

By night: Defend the castle

Hold down the prince icon to advance to night, when monsters attack from different directions. Some can fly or cross rivers. A boss awaits at the end, so strengthen your defenses and protect the castle to the last!
