To avoid resource bottlenecks in Tiles Survive!!, focus all hero upgrade materials exclusively on two primary SSR heroes rather than spreading resources across your full roster. Combine this hero focus with early Development research and targeted building speed-ups to maintain smooth account progression.
Hero Investment Strategy
Spreading hero experience, promotion items, and fragments across every unlocked unit dilutes your overall combat power. High-difficulty campaign stages and competitive events require deep investment in specific units to hit power thresholds.
- Select Two Core SSR Units: Choose two SSR heroes with high base damage output or exceptional utility to serve as your main combat duo.
- Funnel All Upgrade Materials: Direct all available experience points, promotion components, and hero fragments into these two heroes until their stats and levels are maxed.
- Conserve Hero Fragments: Save universal fragments and hero duplicates exclusively for your two main SSR units to boost their star ratings and unlock advanced abilities.
- Target Event Rewards: When participating in events, spend currency on gear enhancement components or core hero upgrade tokens instead of acquiring fragments for heroes outside your main duo.
A fully upgraded main duo will consistently outperform a full roster of low-level, under-geared heroes.
Laboratory Research Priorities
Laboratory research provides permanent account-wide stat boosts. Plan your research upgrades in two distinct phases to support base growth and military expansion.
- Early Phase (Development Tree): Focus initially on technologies that improve construction speed and resource production. Lowering build times and expanding production capacity establishes the economic backbone needed for higher-level upgrades.
- Mid-to-Late Phase (Military Tree): Once base resource production is stable, transition into military research. Prioritize technologies that expand total march capacity and apply combat buffs to your troops.
Building Upgrades and Speed-Up Usage
Speed-ups are limited resources that should be reserved for long-duration structural milestones rather than quick early upgrades.
| Building | Speed-Up Priority | Usage Condition |
|---|---|---|
| Headquarters | High | Use speed-ups to complete upgrades immediately, as Headquarters level gates building slots, troop tiers, and system unlocks. |
| Laboratory | Medium | Keep research active continuously; apply speed-ups primarily when approaching event deadlines or critical power spikes. |
| Resource Depots | Low | Accelerate only when current storage or production rates directly halt your troop training queues. |
Pairing dedicated economic research with a concentrated hero duo ensures your base maintains constant progression without hitting severe resource limits.
