How the Planner Works

The upgrade planner cross-references your wave number against recommended townhall milestones from our levels chart. If your townhall lags behind the wave target, it prioritizes base upgrades. If townhall thresholds are met, it recommends turret investments based on the tier list — prioritizing Sniper max upgrades before wave 18, Shock Turret acquisition before wave 20, and Laser Turret funding after townhall level 7.

Cash estimates use approximate tier costs scaled by wave income. Enable Double Cash if you own the Double Cash gamepass for adjusted income projections. Exact in-game costs may vary with Super Defence balance patches — treat recommendations as strategic direction, not exact Robux-level precision.

General Upgrade Rules

Waves 1–8: Townhall 2–3 before expanding turret count. Waves 9–15: Sniper mid-upgrade + Flame at chokepoint. Waves 16–22: Townhall 5–6, max Sniper, add Shock Turret. Waves 23+: Townhall 7, Laser Turret, premium crate sessions per our crates guide.
