About game
In the immersive tactical strategy game Citadel Defense: Dragon Siege, you must defend your castle against attacking monsters. Gather resources on the battlefield to instantly build defensive towers and save gold for global base upgrades.
How to play
Slide resource tiles (stone, wood, ice, gold) on the game board to match lines of three or more identical elements.
Matching building materials instantly constructs defensive structures on the board — cannons, ballistas, towers, and more, which automatically attack flying dragons. By matching coins, you replenish your gold reserves. Your objective is to plan your moves carefully to build a strong defense and prevent enemies from destroying the Citadel.
Summon new heroes and level them up. The further you progress, the more important tactics become: assemble your squad based on enemy elements. If you lack the power to win, collect accumulated resources from the Garrison, upgrade your fighters, and try again.
