Tiles Survive!! Reservoir Raid Tactics and Scoring

To maximize your alliance score during the Reservoir Raid in Tiles Survive!!, prioritize continuous occupancy of water supply structures over individual skirmishes. Because points accumulate incrementally over time, maintaining a full garrison inside controlled buildings and breaching high-power enemy positions through joint alliance rallies yields far more points per minute than solo combat.

Structure Occupancy and Scoring Strategy

Holding facilities continuously generates the bulk of your alliance's points. Capturing a structure is only the first step; keeping it defended prevents opportunistic enemy counter-attacks and stabilizes your scoring rate.

Rotate Reinforcement Marches: As soon as an alliance member captures a facility, immediately send reinforcement marches to maintain maximum garrison capacity.
Monitor the Map UI: Watch for incoming red attack lines heading toward your occupied buildings. If multiple rallies target your position, send immediate reinforcements or evacuate if the defense cost exceeds the remaining point value.
Pivot to Peripheral Buildings: If rival alliances dominate central facilities, redirect your forces to smaller peripheral structures. Controlling multiple secondary targets often generates higher point totals than repeatedly failing to breach a heavily fortified central node.

Executing Coordinated Alliance Rallies

Solo attacks against fortified structures waste resources and rarely succeed against strong garrison defenses. Use the Rally Strike system to pool troops and heroes into a single strike force.

Initiate the Rally: Have a leading alliance member open a rally on the target structure to aggregate member forces.
Assign Top Formations: Join the rally with your strongest hero formations to push the march output past the garrison defense threshold.
Synchronize Arrival Times: Check march timers and use speed-up items or research bonuses so reinforcing marches arrive in tight sequence, preventing enemy defenders from resetting their garrisons.

March Distance, Stamina, and Healing Priorities

Managing march travel time and hospital resources ensures your alliance stays active throughout the event window.

Combat Factor	Recommended Action	Operational Benefit
Base Location	Relocate shelter closer to central map targets before the event starts.	Cuts march travel duration and improves response time.
Troop Stamina	Commit fully healed, high-power marches only to contested target structures.	Avoids wasting march slots and stamina on low-impact skirmishes.
Hospital Capacity	Heal top-tier SSR heroes first when troop casualties accumulate.	Keeps your primary combat formations functional for upcoming rallies.
