Nimboria : Idle Towers Evolve

Merge towers, evolve defenses, and idle-farm rewards in Nimboria's siege

Begin with basic towers, then merge two identical towers to evolve them into stronger, more powerful defenses. Every evolution boosts your damage, speeds up attacks, and can unlock new abilities—helping you withstand wave after wave of incoming enemies.
Tap your towers to collect coins, then invest your earnings to upgrade tower stats and reinforce your entire defense line. As you progress, you’ll unlock up to 30 unique tower types, each with its own strength tier and combat role, letting you create diverse setups and experiment with different strategies.
Enemies grow tougher and appear in greater numbers over time, so careful planning matters—merge wisely, upgrade consistently, and place towers where they’ll perform best. And even when you’re away, your towers keep fighting automatically, earning rewards through relaxing idle gameplay.
Simple controls, satisfying merges, and endless progression make Nimboria: Idle Towers Evolve easy to pick up—but rewarding to master. Build, merge, evolve, and see how long your defenses can hold!
