General approach to zombies and monsters
Zombie attacks and monsters in Tiles Survive should be planned around squads, heroes, stamina or energy, target choice, and expected rewards. Exact limits, levels, timers, and rewards should be checked in the game.
Do not spend resources and stamina without a plan: first understand why the attack is needed, whether the target fits your account state, and whether it conflicts with other daily routine.
Target choice and preparation
The target level depends on account strength, available heroes, squad setup, current stamina, and rewards shown by the game. There is no universal best zombie level for every player.
When unsure, use a cautious route in the game and do not treat old advice as current after updates without checking it.
Helper role
Tiles Survive Helper can help with repeated checks and supported routine around zombies when that feature is available. It does not guarantee results or promise automatic farming optimization.
Stable use depends on a visible PC game window, free squads, a clear route, and player control over resource spending.
