Last Z: Survival Shooter Dragon Treasure Hunt Grid Strategy

To clear the Dragon Treasure Hunt event grid efficiently in Last Z: Survival Shooter, uncover tiles in a continuous row-by-row pattern starting from one corner and save scanning items for late-stage cleanup. Claim all free daily attempt top-ups at server reset before deciding whether to spend premium currencies on extra board refreshes.

How to Sweep the Treasure Grid

Random clicking wastes daily energy attempts and increases the risk of missing valuable reward caches scattered beneath the grid tiles. Following a structured clearing routine ensures full map coverage while preserving reveal items for optimal moments.

Start at a corner: Begin tile interactions at a single outer edge and move systematically across horizontal or vertical lines.
Maintain linear coverage: Sweep fully across rows or columns before jumping to new areas to keep an accurate mental map of remaining hidden tiles.
Hold scanners for late stages: Save reveal tools and location hints until the board is mostly uncovered. Using scanners on a sparse grid maximizes the chance of pinpointing the final high-value items rather than wasting hints early on crowded boards.

Event Phase	Recommended Action	Strategic Goal
Daily Reset	Claim free energy top-ups and shop tokens	Maximize free interactions before using stockpiled resources
Early Board	Sweep tiles linearly from outer edges	Uncover baseline resources and reduce hidden grid space
Late Board	Activate hints and scanning tools	Locate remaining high-tier chests without blind clicks

Managing Daily Energy Limits and Currency Costs

Participation in the Dragon Treasure Hunt is restricted by a daily limit on energy attempts. Because attempts reset daily across the multi-day event window, consistent participation is required to reach deep reward tiers.

Log in daily: Energy caps prevent endless grinding in a single day. Missing daily resets significantly lowers total board clearance unless premium currency is spent to compensate.
Target specific shop items: Identify whether the current event board contains currencies for hero upgrades or shelter construction materials, then align tile clearing with those priorities.
Evaluate refresh costs: Reward placement relies on random distribution. Avoid buying extra board attempts or refreshes with premium currency unless the value of the remaining items on the board exceeds the exact cost of the attempts.
