Castle Defender Saga is an endless castle defense game. Hold back hordes of determined enemies by placing defenses on your castle tower. Upgrade your units and level up to increase your health and firepower.

How to Play

Hold back the horde

Castle Defender Saga puts you in charge of leading castle defenses. Before each round, you set up your defensive strategy before hitting play and watching your units fight against enemy waves of increasing intensity. Just as you start the fight, you’ll also get the chance to boost your defenses significantly by watching a short ad.

Place new units

Every round you play will earn you gold coins. You can use this currency to purchase new units to place on your castle. These units include mages, knights, bombermen, and summoners.

Upgrade your defenses

Every aspect of your defensive strategy can be upgraded. You can add more archers and improve your castle’s health. But you can also upgrade each unit individually. When you’ve upgraded a unit 10 times, you can use mana to promote them, giving your fighter much greater power.
