Reign: Build & Defend

Build. Defend. Expand.

Build a castle, command your army, and survive the siege. Reign is an offline tower-defense roguelike with village building, real-time battles, and a fresh set of upgrade choices each run.

BUILD YOUR STRONGHOLD
Place farms, lumbermills, quarries, and military buildings. Plan your roads, protect your workers, and turn a small settlement into a fortress.

COMMAND THE DEFENSE
Position archers, infantry, cavalry, and siege engines. Build towers and walls, watch the enemy's approach, and protect your keep when the attack arrives.

MAKE EACH RUN YOUR OWN
Choose from five civilizations: English, French, Japanese, Persians, and Mongols. Pair them with six distinct heroes and draft cards that change your economy, army, and defenses.

KEEP PUSHING
Explore different terrain, climb eight difficulty levels, and push beyond the 16-wave campaign into endless sieges. A guided practice run helps you learn the basics.

Core gameplay works offline. Occasional ads appear only between completed runs, never during combat. The tutorial and your first two completed runs are ad-free. A one-time No Ads purchase removes between-run ads; there are no subscriptions or paid combat advantages.
