Tower Crush

Tower Crush operates on a dual-layer strategic system combining tower merging mechanics with real-time wave defense. The core loop revolves around placing identical tower units on a grid battlefield, then dragging one onto another to create a higher-tier tower with exponentially increased damage output and firing speed. Each merge generates instant power spikes that directly impact your ability to survive progressively difficult enemy waves.

The combat calculation engine processes tower stats including damage per second, range radius, attack speed, and special abilities like splash damage or critical strike chance. Enemy waves scale based on a difficulty multiplier that increases wave health by 15-20% per level while introducing new enemy types with resistance modifiers. The game tracks your total damage output, gold income rate, and tower efficiency to determine upgrade paths and optimal merge timing.

Resource management drives progression through a three-currency economy: gold earned from defeated enemies funds new tower purchases, gems unlock premium tower types with unique abilities, and merge tokens allow instant tower combinations without grid placement restrictions. The auto-battle system can be toggled for passive farming, but manual play yields 30-40% higher gold income through strategic tower repositioning and merge chain optimization during active combat phases.
