🏰 A horde of monsters is spiraling toward your castle──
"Spiral Defense: Arrow Puzzle" is a casual tower-defense puzzle you can play with a single tap. Monsters emerge from a vortex, circle the outer road, and slip inward lap after lap, spiraling ever closer to the castle at the center. Launch your adventurers and strike them down before they reach it!
■ Simple rules, deep strategy
・Tap an adventurer to send it marching straight along its arrow
・A marching adventurer defeats monsters of the SAME color only
・Hit a different color and your adventurer falls — order and timing are everything!
・Idle adventurers are defeated by ANY monster that touches them, so don't wait too long
・Defeat every monster on the stage to clear it!
■ Story Mode (20 stages)
A campaign to save the kingdom. As you progress, Archers, Assassins, Monks, and Dancers join your Warriors, Cavalry, and Priests — each with a new color to master. Every 5th stage brings a mighty Boss with an HP gauge that must be struck again and again by matching-color heroes.
After each victory, visit the tavern and pick just ONE of three randomly offered goods. Stock up on cheap soldiers, or save up for a game-changing treasure? Your budget decides the kingdom's fate. A short opening and ending story rounds out the campaign.
■ Tavern lineup
・Soldiers: extra adventurers who join the next stage
・Slow Timer: slows every enemy for a few seconds on use
・Cannon: deployed on the board, auto-firing along its arrow — but destroyed if an enemy steps on it
・Battle Mage: garrisons the castle and auto-destroys one enemy that gets adjacent — your last line of defense
・Landmine: a single-use trap that destroys whoever steps on it
・And rarely, a legendary Hero appears for hire — the ultimate mercenary who defeats monsters of EVERY color!
■ Dungeon Mode (endless)
How deep can you go? Every floor is randomly generated: a random party of all classes is deployed, and a beatable wave of enemies pours in. Deeper floors add hazard tiles — rocks, warp pads, and spinners. Chase your TOP 10 deepest-floor records!
