Game Guide
The core fun of PolyGun: Idle TD lies in the balance between casual idle gameplay and strategic layout. By mastering the following tips, beginners can quickly break through early bottlenecks and steadily enhance their combat effectiveness.

Initial layout is fundamental. Prioritize path corners and narrow passages as core defense points, where placing area-damage turrets (such as shotgun-type ones) can maximize splash damage coverage to multiple waves of geometric enemies. There’s no need to scatter multiple low-level turrets in the early stage; concentrate resources to upgrade 1-2 core turrets to level 3, which offers far higher output efficiency than scattered layouts. It’s recommended to first use area-damage turrets to deal with swarms, and later add 1 single-target high-damage turret to guard against elite enemies.

Resource management determines progress speed. Follow the "7:3 Rule" for resources obtained by defeating enemies: 70% invested in core turret upgrades, 3% allocated to card enhancements, and the rest kept as emergency reserves. Be sure to complete daily rewards and challenge tasks in a timely manner, as they are the main stable source of early resources. Ensure your defense line is solid before going offline, and use the auto-battle mechanism to accumulate earnings. When you return to the game, you can quickly unlock new turrets or upgrade technologies.

The card system is key to a combat effectiveness leap. Beginners should first unlock universal bonus cards such as "Attack Speed Boost" and "Range Extension" that are compatible with various turrets; before BOSS waves, switch to cards like "Critical Hit Bonus" and "Armor Penetration" to greatly improve elimination efficiency. There’s no need to evenly upgrade all cards; focus on 1-2 core combinations for in-depth development. For example, "Range + Attack Speed" is suitable for swarm defense lines, while "High Damage + Critical Hit" specializes in BOSS battles.

Advanced response requires flexible adjustments. When facing fast-moving small geometric enemies, add slowdown auxiliary facilities to extend their damage-taking time; when encountering large BOSSes, concentrate high-damage turrets on the BOSS’s main path and activate card ultimate skills to continuously reduce its health. After clearing every 5 levels, review defense loopholes, promptly replace inefficient turrets, and adjust layout strategies in advance according to the enemy types of subsequent levels.
Follow the three core principles of "focused layout, concentrated resources, and card adaptation". You can not only enjoy the ease of idle gameplay but also experience the fun of strategic layout, quickly growing from a beginner to a defense master.
