To defend your base against early waves in Starguard: Evo Merge TD, spend your initial gold immediately to fill open board tiles and synthesize pairs of identical units. Prioritizing rapid merges over saving gold keeps your offensive power scaled up and frees up board space for new summons.
Early Board and Resource Priorities
Leaving empty board slots reduces your damage per second and slows down board progression. Keep your board active by spending gold on new summons whenever a slot is open during early waves.
- Spend gold immediately: Invest currency as soon as it is available to maintain constant unit generation.
- Keep tiles filled: Avoid leaving empty slots so your defensive output remains steady.
- Merge pairs quickly: Combine matching identical towers to create higher-tier units with superior damage and attack speed.
Managing Board Slots and Unit Placement
Board space is your primary tactical limitation. Accumulating unmerged units clutters the field and prevents new summons from spawning.
- Clear clogged slots: Combine duplicate low-tier units immediately to make room for incoming summons.
- Prioritize track positions: Place or merge your highest-tier units near critical points along the enemy path to maximize target coverage.
- Sacrifice redundant low-tier units: Merge matching low-level units even if it temporarily reduces total tower count, as higher-tier towers compensate with stronger single-target output and increased range.
Adapting to Harder Waves
While early waves succumb to high unit density, mid-game wave progression introduces higher-health mechanical enemies that basic towers cannot quickly destroy.
| Stage | Defensive Focus | Primary Action |
|---|---|---|
| Early Waves | Quantity & Tile Saturation | Spend gold continuously to fill all tiles and merge basic duplicates. |
| Mid Waves | Single-Target & Burst Damage | Focus merges on creating 1–2 high-tier towers near critical path bends. |
| Difficulty Spikes | Target Specific Threats | Reposition or evolve units toward damage types that counter leaking enemy types. |
If enemies consistently reach your outpost, shift your priority from filling the board to evolving single high-tier towers that provide concentrated burst damage or crowd control.
